# Unit test writing using a multi-step prompt

Complex tasks, such as writing unit tests, can benefit from multi-step prompts. In contrast to a single prompt, a multi-step prompt generates text from GPT and then feeds that output text back into subsequent prompts. This can help in cases where you want GPT to reason things out before answering, or brainstorm a plan before executing it.

In this notebook, we use a 3-step prompt to write unit tests in Python using the following steps:

1. **Explain**: Given a Python function, we ask GPT to explain what the function is doing and why.
2. **Plan**: We ask GPT to plan a set of unit tests for the function.
    - If the plan is too short, we ask GPT to elaborate with more ideas for unit tests.
3. **Execute**: Finally, we instruct GPT to write unit tests that cover the planned cases.

The code example illustrates a few embellishments on the chained, multi-step prompt:

- Conditional branching (e.g., asking for elaboration only if the first plan is too short)
- The choice of different models for different steps
- A check that re-runs the function if the output is unsatisfactory (e.g., if the output code cannot be parsed by Python's `ast` module)
- Streaming output so that you can start reading the output before it's fully generated (handy for long, multi-step outputs)


```python

    A good unit test suite should aim to:
    - Test the function's behavior for a wide range of possible inputs
    - Test edge cases that the author may not have foreseen
    - Take advantage of the features of `pytest` to make the tests easy to write and maintain
    - Be easy to read and understand, with clean code and descriptive names
    - Be deterministic, so that the tests always pass or fail in the same way
    
    To help unit test the function above, list diverse scenarios that the function should be able to handle (and under each scenario, include a few examples as sub-bullets).

    In addition to those scenarios above, list a few rare or unexpected edge cases (and as before, under each edge case, include a few examples as sub-bullets).

Make sure to check any code before using it, as GPT makes plenty of mistakes (especially on character-based tasks like this one). For best results, use the most powerful model (GPT-4, as of May 2023).

# How to use the moderation API

**Note:** This guide is designed to complement our Guardrails Cookbook by providing a more focused look at moderation techniques. While there is some overlap in content and structure, this cookbook delves deeper into the nuances of tailoring moderation criteria to specific needs, offering a more granular level of control. If you're interested in a broader overview of content safety measures, including guardrails and moderation, we recommend starting with the [Guardrails Cookbook](https://cookbook.openai.com/examples/how_to_use_guardrails). Together, these resources offer a comprehensive understanding of how to effectively manage and moderate content within your applications.

Moderation, much like guardrails in the physical world, serves as a preventative measure to ensure that your application remains within the bounds of acceptable and safe content. Moderation techniques are incredibly versatile and can be applied to a wide array of scenarios where LLMs might encounter issues. This notebook is designed to offer straightforward examples that can be adapted to suit your specific needs, while also discussing the considerations and trade-offs involved in deciding whether to implement moderation and how to go about it. This notebook will use our [Moderation API](https://platform.openai.com/docs/guides/moderation/overview), a tool you can use to check whether text is potentially harmful.

This notebook will concentrate on:

- **Input Moderation:** Identifying and flagging inappropriate or harmful content before it is processed by your LLM.
- **Output Moderation:** Reviewing and validating the content generated by your LLM before it reaches the end user.
- **Custom Moderation:** Tailoring moderation criteria and rules to suit the specific needs and context of your application, ensuring a personalized and effective content control mechanism.

```

### 1. Input moderation
Input Moderation focuses on preventing harmful or inappropriate content from reaching the LLM, with common applications including:
- **Content Filtering:** Prevent the spread of harmful content such as hate speech, harassment, explicit material, and misinformation on social media, forums, and content creation platforms.
- **Community Standards Enforcement:** Ensure that user interactions, such as comments, forum posts, and chat messages, adhere to the community guidelines and standards of online platforms, including educational environments, gaming communities, or dating apps.
- **Spam and Fraud Prevention:** Filter out spam, fraudulent content, and misleading information in online forums, comment sections, e-commerce platforms, and customer reviews.

These measures act as preventive controls, operating before or alongside the LLM to alter your application's behavior if specific criteria are met.

#### Embrace async
A common design to minimize latency is to send your moderations asynchronously along with your main LLM call. If your moderation gets triggered you send back a placeholder response, otherwise send back the LLM response. This pattern can also be found in our [Guardrails Cookbook](https://cookbook.openai.com/examples/how_to_use_guardrails). It's important to note that while the async mode is effective in minimizing latency, it can also lead to unnecessary costs. Specifically, you could avoid completion costs if the content is flagged before processing. Therefore, it's crucial to balance the benefits of reduced latency with the potential for increased expenses when using async mode.

We'll use this approach, creating an execute_chat_with_moderation function that will run our LLM's get_chat_response and the check_expression moderation function in parallel, and return the LLM response only if the moderation returns False (not triggered).

#### Workflow:
We will create a workflow that incorporates the Moderation API to check user input for any potentially unsafe content before it is sent to the Language Model (LLM). This ensures that only appropriate content is processed further in the application.

1. Receive an input from the user
2. Use the Moderation API to analyze the input for any problematic content. 
3. **Conditional Processing:** 
- If the input is flagged by the moderation check, handle it accordingly (e.g., reject the input, ask the user to rephrase, etc.).
- If the input is not flagged, pass it to the LLM for further processing.

We will demonstrate this workflow with two example prompts.

    I can help you with that! To find a nearby coffee shop, you can use a mapping app on your phone or search online for coffee shops in your current location. Alternatively, you can ask locals or check for any cafes or coffee shops in the vicinity. Enjoy your coffee!

Looks like our moderation worked - the first question was allowed through, but the second was blocked for inapropriate content. Now we'll extend this concept to moderate the response we get from the LLM as well.

### 2. Output moderation

Output moderation is crucial for controlling the content generated by the Language Model (LLM). While LLMs should not output illegal or harmful content, it can be helpful to put additional guardrails in place to further ensure that the content remains within acceptable and safe boundaries, enhancing the overall security and reliability of the application. Common types of output moderation include:

- **Content Quality Assurance:** Ensure that generated content, such as articles, product descriptions, and educational materials, is accurate, informative, and free from inappropriate information.
- **Community Standards Compliance:** Maintain a respectful and safe environment in online forums, discussion boards, and gaming communities by filtering out hate speech, harassment, and other harmful content.
- **User Experience Enhancement:** Improve the user experience in chatbots and automated services by providing responses that are polite, relevant, and free from any unsuitable language or content.

In all these scenarios, output moderation plays a crucial role in maintaining the quality and integrity of the content generated by language models, ensuring that it meets the standards and expectations of the platform and its users.

#### Setting moderation thresholds
OpenAI has selected thresholds for moderation categories that balance precision and recall for our use cases, but your use case or tolerance for moderation may be different. Setting this threshold is a common area for optimization - we recommend building an evaluation set and grading the results using a confusion matrix to set the right tolerance for your moderation. The trade-off here is generally:

- More false positives leads to a fractured user experience, where customers get annoyed and the assistant seems less helpful.
- More false negatives can cause lasting harm to your business, as people get the assistant to answer inappropriate questions, or provide inappropriate responses.

For example, on a platform dedicated to creative writing, the moderation threshold for certain sensitive topics might be set higher to allow for greater creative freedom while still providing a safety net to catch content that is clearly beyond the bounds of acceptable expression. The trade-off is that some content that might be considered inappropriate in other contexts is allowed, but this is deemed acceptable given the platform's purpose and audience expectations.

#### Workflow:
We will create a workflow that incorporates the Moderation API to check the LLM response for any potentially unsafe content before it is sent to the Language Model (LLM). This ensures that only appropriate content is displayed to the user.

1. Receive an input from the user
2. Send prompt to LLM and generate a response
3. Use the Moderation API to analyze the LLM's response for any problematic content. 
3. **Conditional Processing:** 
- If the response is flagged by the moderation check, handle it accordingly (e.g., reject the response, show a placeholder message, etc.).
- If the response is not flagged, display it to the user.

We will demonstrate this workflow with the previous two example prompts.

As observed, the first two examples behaved as expected. However, the "interesting example" did not perform as anticipated. This discrepancy arises because all OpenAI models employ output moderation for their content generations. Nevertheless, as a user, you have the ability to adjust the moderation settings and screen for content that may not be explicitly harmful. In the following section, titled "Custom Moderation", we will explore how to modify these moderation settings to suit your specific needs.

### 3. Custom moderation

**Note: This section does not use the Moderation API.**

Custom moderation provides a tailored approach to content filtering, allowing for precise adherence to specific community standards or topics, making it an ideal choice for niche platforms or specialized content. Unlike the general categories covered by the moderation API, custom moderation offers a higher degree of control and requires more effort to set up and maintain. It shares the common goal of ensuring content safety with guardrails, focusing on setting criteria to filter and manage content, whether it's user input or output from language models. Custom moderation can be an alternative or an extension to the moderation API, that uses our completions endpoint. For those interested in exploring guardrails further, a cookbook with examples and guidance is available [here](https://cookbook.openai.com/examples/how_to_use_guardrails).

#### Workflow
We will implement a small example to showcase custom moderation. We will use an extra call to gpt-4o mini to assess messages and decide if they should be moderated or not.

### Conclusion

In conclusion, this notebook has explored the essential role of moderation in applications powered by language models (LLMs). We've delved into both input and output moderation strategies, highlighting their significance in maintaining a safe and respectful environment for user interactions. Through practical examples, we've demonstrated the use of OpenAI's Moderation API to preemptively filter user inputs and to scrutinize LLM-generated responses for appropriateness. The implementation of these moderation techniques is crucial for upholding the integrity of your application and ensuring a positive experience for your users.

As you further develop your application, consider the ongoing refinement of your moderation strategies through custom moderations. This may involve tailoring moderation criteria to your specific use case or integrating a combination of machine learning models and rule-based systems for a more nuanced analysis of content. Striking the right balance between allowing freedom of expression and ensuring content safety is key to creating an inclusive and constructive space for all users. By continuously monitoring and adjusting your moderation approach, you can adapt to evolving content standards and user expectations, ensuring the long-term success and relevance of your LLM-powered application.

# Retrieval Augmented Generation with a Graph Database

This notebook shows how to use LLMs in combination with [Neo4j](https://neo4j.com/), a graph database, to perform Retrieval Augmented Generation (RAG).

### Why use RAG?

If you want to use LLMs to generate answers based on your own content or knowledge base, instead of providing large context when prompting the model, you can fetch the relevant information in a database and use this information to generate a response. 

This allows you to:
- Reduce hallucinations
- Provide relevant, up to date information to your users
- Leverage your own content/knowledge base

### Why use a graph database?

If you have data where relationships between data points are important and you might want to leverage that, then it might be worth considering graph databases instead of traditional relational databases.

Graph databases are good to address the following:
- Navigating deep hierarchies
- Finding hidden connections between items
- Discovering relationships between items

### Use cases 

Graph databases are particularly relevant for recommendation systems, network relationships or analysing correlation between data points.  

Example use cases for RAG with graph databases include:
- Recommendation chatbot
- AI-augmented CRM 
- Tool to analyse customer behavior with natural language

Depending on your use case, you can assess whether using a graph database makes sense. 

In this notebook, we will build a **product recommendation chatbot**, with a graph database that contains Amazon products data.


## Setup

We will start by installing and importing the relevant libraries.  

Make sure you have your OpenAI account set up and you have your OpenAI API key handy. 


```python
# Optional: run to install the libraries locally if you haven't already 
!pip3 install langchain
!pip3 install openai
!pip3 install neo4j
```


```python
import os
import json 
import pandas as pd
```


```python
# Optional: run to load environment variables from a .env file.
# This is not required if you have exported your env variables in another way or if you set it manually
!pip3 install python-dotenv
from dotenv import load_dotenv
load_dotenv()

# Set the OpenAI API key env variable manually
# os.environ["OPENAI_API_KEY"] = "<your_api_key>"

# print(os.environ["OPENAI_API_KEY"])
```

## Dataset

We will use a dataset that was created from a relational database and converted to a json format, creating relationships between entities with the completions API.

We will then load this data into the graph db to be able to query it.

### Loading dataset


```python
# Loading a json dataset from a file
file_path = 'data/amazon_product_kg.json'

with open(file_path, 'r') as file:
    jsonData = json.load(file)
```


```python
df =  pd.read_json(file_path)
df.head()
```

## Querying the database

### Creating vector indexes

In order to efficiently search our database for terms closely related to user queries, we need to use embeddings. To do this, we will create vector indexes on each type of property.

We will be using the OpenAIEmbeddings Langchain utility. It's important to note that Langchain adds a pre-processing step, so the embeddings will slightly differ from those generated directly with the OpenAI embeddings API.


```python
from langchain.vectorstores.neo4j_vector import Neo4jVector
from langchain.embeddings.openai import OpenAIEmbeddings
embeddings_model = "text-embedding-3-small"
```

### Extracting entities from the prompt

However, there is little added value here compared to just writing the Cypher queries ourselves, and it is prone to error.

Indeed, asking an LLM to generate a Cypher query directly might result in the wrong parameters being used, whether it's the entity type or the relationship type, as is the case above.

We will instead use LLMs to decide what to search for, and then generate the corresponding Cypher queries using templates.

For this purpose, we will instruct our model to find relevant entities in the user prompt that can be used to query our database.

    You are a helpful agent designed to fetch information from a graph database. 
    
    The graph database links products to the following entity types:
    {json.dumps(entity_types)}
    
    Each link has one of the following relationships:
    {json.dumps(relation_types)}

    Depending on the user prompt, determine if it possible to answer with the graph database.
        
    The graph database can match products with multiple relationships to several entities.
    
    Example user input:
    "Which blue clothing items are suitable for adults?"
    
    There are three relationships to analyse:
    1. The mention of the blue color means we will search for a color similar to "blue"
    2. The mention of the clothing items means we will search for a category similar to "clothing"
    3. The mention of adults means we will search for an age_group similar to "adults"
    
    
    Return a json object following the following rules:
    For each relationship to analyse, add a key value pair with the key being an exact match for one of the entity types provided, and the value being the value relevant to the user query.
    
    For the example provided, the expected output would be:
    {{
        "color": "blue",
        "category": "clothing",
        "age_group": "adults"
    }}
    
    If there are no relevant entities in the user prompt, return an empty json object.

### Generating queries

Now that we know what to look for, we can generate the corresponding Cypher queries to query our database. 

However, the entities extracted might not be an exact match with the data we have, so we will use the GDS cosine similarity function to return products that have relationships with entities similar to what the user is asking.


```python
def create_embedding(text):
    result = client.embeddings.create(model=embeddings_model, input=text)
    return result.data[0].embedding
```


```python
# The threshold defines how closely related words should be. Adjust the threshold to return more or less results
def create_query(text, threshold=0.81):
    query_data = json.loads(text)
    # Creating embeddings
    embeddings_data = []
    for key, val in query_data.items():
        if key != 'product':
            embeddings_data.append(f"${key}Embedding AS {key}Embedding")
    query = "WITH " + ",\n".join(e for e in embeddings_data)
    # Matching products to each entity
    query += "\nMATCH (p:Product)\nMATCH "
    match_data = []
    for key, val in query_data.items():
        if key != 'product':
            relationship = entity_relationship_match[key]
            match_data.append(f"(p)-[:{relationship}]->({key}Var:{key})")
    query += ",\n".join(e for e in match_data)
    similarity_data = []
    for key, val in query_data.items():
        if key != 'product':
            similarity_data.append(f"gds.similarity.cosine({key}Var.embedding, ${key}Embedding) > {threshold}")
    query += "\nWHERE "

### Finding similar items 

We can then leverage the graph db to find similar products based on common characteristics.

This is where the use of a graph db really comes into play.

For example, we can look for products that are the same category and have another characteristic in common, or find products that have relationships to the same entities. 

This criteria is arbitrary and completely depends on what is the most relevant in relation to your use case.

### Finding similar items 

We can then leverage the graph db to find similar products based on common characteristics.

This is where the use of a graph db really comes into play.

For example, we can look for products that are the same category and have another characteristic in common, or find products that have relationships to the same entities. 

This criteria is arbitrary and completely depends on what is the most relevant in relation to your use case.


```python
# Adjust the relationships_threshold to return products that have more or less relationships in common
def query_similar_items(product_id, relationships_threshold = 3):
    
    similar_items = []
        
    # Fetching items in the same category with at least 1 other entity in common
    query_category = '''
            MATCH (p:Product {id: $product_id})-[:hasCategory]->(c:category)
            MATCH (p)-->(entity)
            WHERE NOT entity:category
            MATCH (n:Product)-[:hasCategory]->(c)
            MATCH (n)-->(commonEntity)
            WHERE commonEntity = entity AND p.id <> n.id
            RETURN DISTINCT n;
        '''
    

    result_category = graph.query(query_category, params={"product_id": int(product_id)})
    #print(f"{len(result_category)} similar items of the same category were found.")
          
    # Fetching items with at least n (= relationships_threshold) entities in common
    query_common_entities = '''
        MATCH (p:Product {id: $product_id})-->(entity),
            (n:Product)-->(entity)
            WHERE p.id <> n.id
            WITH n, COUNT(DISTINCT entity) AS commonEntities
            WHERE commonEntities >= $threshold
            RETURN n;
        '''
    result_common_entities = graph.query(query_common_entities, params={"product_id": int(product_id), "threshold": relationships_threshold})
    #print(f"{len(result_common_entities)} items with at least {relationships_threshold} things in common were found.")

    for i in result_category:
        similar_items.append({
            "id": i['n']['id'],
            "name": i['n']['name']
        })
            
    for i in result_common_entities:
        result_id = i['n']['id']
        if not any(item['id'] == result_id for item in similar_items):
            similar_items.append({
                "id": result_id,
                "name": i['n']['name']
            })
    return similar_items

## Final result

Now that we have all the pieces working, we will stitch everything together. 

We can also add a fallback option to do a product name/title similarity search if we can't find relevant entities in the user prompt.

We will explore 2 options, one with a Langchain agent for a conversational experience, and one that is more deterministic based on code only. 

Depending on your use case, you might choose one or the other option and tailor it to your needs.

### Building a Langchain agent

We will create a Langchain agent to handle conversations and probing the user for more context.

We need to define exactly how the agent should behave, and give it access to our query and similarity search tools.

### Building a code-only experience

As our experiments show, using an agent for this type of task might not be the best option.

Indeed, the agent seems to retrieve results from the tools, but comes up with made-up responses. 

For this specific use case, if the conversational aspect is less relevant, we can actually create a function that will call our previously-defined tasks and provide an answer.

## Conclusion

### User experience

When the primary objective is to extract specific information from our database, Large Language Models (LLMs) can significantly enhance our querying capabilities.

However, it's crucial to base much of this process on robust code logic to ensure a foolproof user experience.

For crafting a genuinely conversational chatbot, further exploration in prompt engineering is necessary, possibly incorporating few-shot examples. This approach helps mitigate the risk of generating inaccurate or misleading information and ensures more precise responses.

Ultimately, the design choice depends on the desired user experience. For instance, if the aim is to create a visual recommendation system, the importance of a conversational interface is less relevant.

### Working with a knowledge graph 

Retrieving content from a knowledge graph adds complexity but can be useful if you want to leverage connections between items. 

The querying part of this notebook would work on a relational database as well, the knowledge graph comes in handy when we want to couple the results with similar items that the graph is surfacing. 

Considering the added complexity, make sure using a knowledge graph is the best option for your use case.
If it is the case, feel free to refine what this cookbook presents to match your needs and perform even better!

# Data preparation and analysis for chat model fine-tuning

This notebook serves as a tool to preprocess and analyze the chat dataset used for fine-tuning a chat model. 
It checks for format errors, provides basic statistics, and estimates token counts for fine-tuning costs.
The method shown here corresponds to the [current fine-tuning method](https://platform.openai.com/docs/guides/fine-tuning) for gpt-3.5-turbo.
See [legacy fine-tuning](https://platform.openai.com/docs/guides/legacy-fine-tuning) for models like babbage-002 and davinci-002.


```python
import json
import tiktoken # for token counting
import numpy as np
from collections import defaultdict
```

## Data loading

We first load the chat dataset from an [example JSONL file](https://github.com/openai/openai-cookbook/blob/main/examples/data/toy_chat_fine_tuning.jsonl).


```python
data_path = "data/toy_chat_fine_tuning.jsonl"

# Load the dataset
with open(data_path, 'r', encoding='utf-8') as f:
    dataset = [json.loads(line) for line in f]

# Initial dataset stats
print("Num examples:", len(dataset))
print("First example:")
for message in dataset[0]["messages"]:
    print(message)
```

    Num examples: 5
    First example:
    {'role': 'system', 'content': 'You are a happy assistant that puts a positive spin on everything.'}
    {'role': 'user', 'content': 'I fell off my bike today.'}
    {'role': 'assistant', 'content': "It's great that you're getting exercise outdoors!"}


## Format validation

We can perform a variety of error checks to validate that each conversation in the dataset adheres to the format expected by the fine-tuning API. Errors are categorized based on their nature for easier debugging.

1. **Data Type Check**: Checks whether each entry in the dataset is a dictionary (`dict`). Error type: `data_type`.
2. **Presence of Message List**: Checks if a `messages` list is present in each entry. Error type: `missing_messages_list`.
3. **Message Keys Check**: Validates that each message in the `messages` list contains the keys `role` and `content`. Error type: `message_missing_key`.
4. **Unrecognized Keys in Messages**: Logs if a message has keys other than `role`, `content`, `weight`, `function_call`, and `name`. Error type: `message_unrecognized_key`.
5. **Role Validation**: Ensures the `role` is one of "system", "user", or "assistant". Error type: `unrecognized_role`.
6. **Content Validation**: Verifies that `content` has textual data and is a string. Error type: `missing_content`.
7. **Assistant Message Presence**: Checks that each conversation has at least one message from the assistant. Error type: `example_missing_assistant_message`.

The code below performs these checks, and outputs counts for each type of error found are printed. This is useful for debugging and ensuring the dataset is ready for the next steps.

2. **Presence of Message List**: Checks if a `messages` list is present in each entry. Error type: `missing_messages_list`.
3. **Message Keys Check**: Validates that each message in the `messages` list contains the keys `role` and `content`. Error type: `message_missing_key`.
4. **Unrecognized Keys in Messages**: Logs if a message has keys other than `role`, `content`, `weight`, `function_call`, and `name`. Error type: `message_unrecognized_key`.
5. **Role Validation**: Ensures the `role` is one of "system", "user", or "assistant". Error type: `unrecognized_role`.
6. **Content Validation**: Verifies that `content` has textual data and is a string. Error type: `missing_content`.
7. **Assistant Message Presence**: Checks that each conversation has at least one message from the assistant. Error type: `example_missing_assistant_message`.

The code below performs these checks, and outputs counts for each type of error found are printed. This is useful for debugging and ensuring the dataset is ready for the next steps.



```python
# Format error checks
format_errors = defaultdict(int)

for ex in dataset:
    if not isinstance(ex, dict):
        format_errors["data_type"] += 1
        continue
        
    messages = ex.get("messages", None)
    if not messages:
        format_errors["missing_messages_list"] += 1
        continue
        
    for message in messages:
        if "role" not in message or "content" not in message:
            format_errors["message_missing_key"] += 1
        
        if any(k not in ("role", "content", "name", "function_call", "weight") for k in message):
            format_errors["message_unrecognized_key"] += 1
        
        if message.get("role", None) not in ("system", "user", "assistant", "function"):
            format_errors["unrecognized_role"] += 1
            
        content = message.get("content", None)
        function_call = message.get("function_call", None)
        
        if (not content and not function_call) or not isinstance(content, str):
            format_errors["missing_content"] += 1
    
    if not any(message.get("role", None) == "assistant" for message in messages):
        format_errors["example_missing_assistant_message"] += 1

if format_errors:
    print("Found errors:")
    for k, v in format_errors.items():
        print(f"{k}: {v}")
else:
    print("No errors found")
```

    No errors found

```

## Data Warnings and Token Counts 

With some lightweight analysis we can identify potential issues in the dataset, like missing messages, and provide statistical insights into message and token counts.

1. **Missing System/User Messages**: Counts the number of conversations missing a "system" or "user" message. Such messages are critical for defining the assistant's behavior and initiating the conversation.
2. **Number of Messages Per Example**: Summarizes the distribution of the number of messages in each conversation, providing insight into dialogue complexity.
3. **Total Tokens Per Example**: Calculates and summarizes the distribution of the total number of tokens in each conversation. Important for understanding fine-tuning costs.
4. **Tokens in Assistant's Messages**: Calculates the number of tokens in the assistant's messages per conversation and summarizes this distribution. Useful for understanding the assistant's verbosity.
5. **Token Limit Warnings**: Checks if any examples exceed the maximum token limit (16,385 tokens), as such examples will be truncated during fine-tuning, potentially resulting in data loss.

## Cost Estimation

    Dataset has ~4306 tokens that will be charged for during training
    By default, you'll train for 20 epochs on this dataset
    By default, you'll be charged for ~86120 tokens

# Clustering for Transaction Classification

This notebook covers use cases where your data is unlabelled but has features that can be used to cluster them into meaningful categories. The challenge with clustering is making the features that make those clusters stand out human-readable, and that is where we'll look to use GPT-3 to generate meaningful cluster descriptions for us. We can then use these to apply labels to a previously unlabelled dataset.

To feed the model we use embeddings created using the approach displayed in the notebook [Multiclass classification for transactions Notebook](Multiclass_classification_for_transactions.ipynb), applied to the full 359 transactions in the dataset to give us a bigger pool for learning

## Setup


```python
# optional env import
from dotenv import load_dotenv
load_dotenv()
```




    True




```python
# imports
 
from openai import OpenAI
import pandas as pd
import numpy as np

COMPLETIONS_MODEL = "gpt-3.5-turbo"

# This path leads to a file with data and precomputed embeddings
embedding_path = "data/library_transactions_with_embeddings_359.csv"

```

## Clustering

We'll reuse the approach from the [Clustering Notebook](Clustering.ipynb), using K-Means to cluster our dataset using the feature embeddings we created previously. We'll then use the Completions endpoint to generate cluster descriptions for us and judge their effectiveness

### Conclusion

We now have five new clusters that we can use to describe our data. Looking at the visualisation some of our clusters have some overlap and we'll need some tuning to get to the right place, but already we can see that GPT-3 has made some effective inferences. In particular, it picked up that items including legal deposits were related to literature archival, which is true but the model was given no clues on. Very cool, and with some tuning we can create a base set of clusters that we can then use with a multiclass classifier to generalise to other transactional datasets we might use.

# Recommendation using embeddings and nearest neighbor search

Recommendations are widespread across the web.

- 'Bought that item? Try these similar items.'
- 'Enjoy that book? Try these similar titles.'
- 'Not the help page you were looking for? Try these similar pages.'

This notebook demonstrates how to use embeddings to find similar items to recommend. In particular, we use [AG's corpus of news articles](http://groups.di.unipi.it/~gulli/AG_corpus_of_news_articles.html) as our dataset.

Our model will answer the question: given an article, what other articles are most similar to it?


```python
import pandas as pd
import pickle

from utils.embeddings_utils import (
    get_embedding,
    distances_from_embeddings,
    tsne_components_from_embeddings,
    chart_from_components,
    indices_of_nearest_neighbors_from_distances,
)

EMBEDDING_MODEL = "text-embedding-3-small"

```

### 2. Load data

Next, let's load the AG news data and see what it looks like.


```python
# load data (full dataset available at http://groups.di.unipi.it/~gulli/AG_corpus_of_news_articles.html)
dataset_path = "data/AG_news_samples.csv"
df = pd.read_csv(dataset_path)

n_examples = 5
df.head(n_examples)

```

### 3. Build cache to save embeddings

Before getting embeddings for these articles, let's set up a cache to save the embeddings we generate. In general, it's a good idea to save your embeddings so you can re-use them later. If you don't save them, you'll pay again each time you compute them again.

The cache is a dictionary that maps tuples of `(text, model)` to an embedding, which is a list of floats. The cache is saved as a Python pickle file.


```python
# establish a cache of embeddings to avoid recomputing
# cache is a dict of tuples (text, model) -> embedding, saved as a pickle file

# set path to embedding cache
embedding_cache_path = "data/recommendations_embeddings_cache.pkl"

# load the cache if it exists, and save a copy to disk
try:
    embedding_cache = pd.read_pickle(embedding_cache_path)
except FileNotFoundError:
    embedding_cache = {}
with open(embedding_cache_path, "wb") as embedding_cache_file:
    pickle.dump(embedding_cache, embedding_cache_file)

# define a function to retrieve embeddings from the cache if present, and otherwise request via the API
def embedding_from_string(
    string: str,
    model: str = EMBEDDING_MODEL,
    embedding_cache=embedding_cache
) -> list:
    """Return embedding of given string, using a cache to avoid recomputing."""
    if (string, model) not in embedding_cache.keys():
        embedding_cache[(string, model)] = get_embedding(string, model)
        with open(embedding_cache_path, "wb") as embedding_cache_file:
            pickle.dump(embedding_cache, embedding_cache_file)
    return embedding_cache[(string, model)]

```

Let's check that it works by getting an embedding.

    return embedding_cache[(string, model)]

```

Let's check that it works by getting an embedding.


```python
# as an example, take the first description from the dataset
example_string = df["description"].values[0]
print(f"\nExample string: {example_string}")

# print the first 10 dimensions of the embedding
example_embedding = embedding_from_string(example_string)
print(f"\nExample embedding: {example_embedding[:10]}...")

```

    
    Example string: BRITAIN: BLAIR WARNS OF CLIMATE THREAT Prime Minister Tony Blair urged the international community to consider global warming a dire threat and agree on a plan of action to curb the  quot;alarming quot; growth of greenhouse gases.
    
    Example embedding: [0.0545826330780983, -0.00428084097802639, 0.04785159230232239, 0.01587914116680622, -0.03640881925821304, 0.0143799539655447, -0.014267769642174244, -0.015175441280007362, -0.002344391541555524, 0.011075624264776707]...

### 5. Example recommendations

Let's look for articles similar to first one, which was about Tony Blair.


```python
article_descriptions = df["description"].tolist()

tony_blair_articles = print_recommendations_from_strings(
    strings=article_descriptions,  # let's base similarity off of the article description
    index_of_source_string=0,  # articles similar to the first one about Tony Blair
    k_nearest_neighbors=5,  # 5 most similar articles
)

```

Pretty good! 4 of the 5 recommendations explicitly mention Tony Blair and the fifth is an article from London about climate change, topics that might be often associated with Tony Blair.

Let's see how our recommender does on the second example article about NVIDIA's new chipset with more security.


```python
chipset_security_articles = print_recommendations_from_strings(
    strings=article_descriptions,  # let's base similarity off of the article description
    index_of_source_string=1,  # let's look at articles similar to the second one about a more secure chipset
    k_nearest_neighbors=5,  # let's look at the 5 most similar articles
)

```

    Source string: PC World - Upcoming chip set will include built-in security features for your PC.
    
            --- Recommendation #1 (nearest neighbor 1 of 5) ---
            String: PC World - Updated antivirus software for businesses adds intrusion prevention features.
            Distance: 0.422
    
            --- Recommendation #2 (nearest neighbor 2 of 5) ---
            String: PC World - Symantec, McAfee hope raising virus-definition fees will move users to\  suites.
            Distance: 0.518
    
            --- Recommendation #3 (nearest neighbor 3 of 5) ---
            String: originally offered on notebook PCs -- to its Opteron 32- and 64-bit x86 processors for server applications. The technology will help servers to run 
            Distance: 0.522
    
            --- Recommendation #4 (nearest neighbor 4 of 5) ---
            String: PC World - Send your video throughout your house--wirelessly--with new gateways and media adapters.
            Distance: 0.532
    
            --- Recommendation #5 (nearest neighbor 5 of 5) ---
            String: Chips that help a computer's main microprocessors perform specific types of math problems are becoming a big business once again.\
            Distance: 0.532


From the printed distances, you can see that the #1 recommendation is much closer than all the others (0.11 vs 0.14+). And the #1 recommendation looks very similar to the starting article - it's another article from PC World about increasing computer security. Pretty good! 

## Appendix: Using embeddings in more sophisticated recommenders

A more sophisticated way to build a recommender system is to train a machine learning model that takes in tens or hundreds of signals, such as item popularity or user click data. Even in this system, embeddings can be a very useful signal into the recommender, especially for items that are being 'cold started' with no user data yet (e.g., a brand new product added to the catalog without any clicks yet).

## Appendix: Using embeddings to visualize similar articles

To get a sense of what our nearest neighbor recommender is doing, let's visualize the article embeddings. Although we can't plot the 2048 dimensions of each embedding vector, we can use techniques like [t-SNE](https://en.wikipedia.org/wiki/T-distributed_stochastic_neighbor_embedding) or [PCA](https://en.wikipedia.org/wiki/Principal_component_analysis) to compress the embeddings down into 2 or 3 dimensions, which we can chart.

Before visualizing the nearest neighbors, let's visualize all of the article descriptions using t-SNE. Note that t-SNE is not deterministic, meaning that results may vary from run to run.

Although we can't plot the 2048 dimensions of each embedding vector, we can use techniques like [t-SNE](https://en.wikipedia.org/wiki/T-distributed_stochastic_neighbor_embedding) or [PCA](https://en.wikipedia.org/wiki/Principal_component_analysis) to compress the embeddings down into 2 or 3 dimensions, which we can chart.

Before visualizing the nearest neighbors, let's visualize all of the article descriptions using t-SNE. Note that t-SNE is not deterministic, meaning that results may vary from run to run.


```python
# get embeddings for all article descriptions
embeddings = [embedding_from_string(string) for string in article_descriptions]
# compress the 2048-dimensional embeddings into 2 dimensions using t-SNE
tsne_components = tsne_components_from_embeddings(embeddings)
# get the article labels for coloring the chart
labels = df["label"].tolist()

chart_from_components(
    components=tsne_components,
    labels=labels,
    strings=article_descriptions,
    width=600,
    height=500,
    title="t-SNE components of article descriptions",
)

```



As you can see in the chart above, even the highly compressed embeddings do a good job of clustering article descriptions by category. And it's worth emphasizing: this clustering is done with no knowledge of the labels themselves!

Also, if you look closely at the most egregious outliers, they are often due to mislabeling rather than poor embedding. For example, the majority of the blue World points in the green Sports cluster appear to be Sports stories.

Next, let's recolor the points by whether they are a source article, its nearest neighbors, or other.


```python
# create labels for the recommended articles
def nearest_neighbor_labels(
    list_of_indices: list[int],
    k_nearest_neighbors: int = 5
) -> list[str]:
    """Return a list of labels to color the k nearest neighbors."""
    labels = ["Other" for _ in list_of_indices]
    source_index = list_of_indices[0]
    labels[source_index] = "Source"
    for i in range(k_nearest_neighbors):
        nearest_neighbor_index = list_of_indices[i + 1]
        labels[nearest_neighbor_index] = f"Nearest neighbor (top {k_nearest_neighbors})"
    return labels


tony_blair_labels = nearest_neighbor_labels(tony_blair_articles, k_nearest_neighbors=5)
chipset_security_labels = nearest_neighbor_labels(chipset_security_articles, k_nearest_neighbors=5
)

```

    """Return a list of labels to color the k nearest neighbors."""

    source_index = list_of_indices[0]
    labels[source_index] = "Source"
    for i in range(k_nearest_neighbors):
        nearest_neighbor_index = list_of_indices[i + 1]
        labels[nearest_neighbor_index] = f"Nearest neighbor (top {k_nearest_neighbors})"
    return labels


tony_blair_labels = nearest_neighbor_labels(tony_blair_articles, k_nearest_neighbors=5)
chipset_security_labels = nearest_neighbor_labels(chipset_security_articles, k_nearest_neighbors=5
)

```


```python
# a 2D chart of nearest neighbors of the Tony Blair article
chart_from_components(
    components=tsne_components,
    labels=tony_blair_labels,
    strings=article_descriptions,
    width=600,
    height=500,
    title="Nearest neighbors of the Tony Blair article",
    category_orders={"label": ["Other", "Nearest neighbor (top 5)", "Source"]},
)

```



Looking at the 2D chart above, we can see that the articles about Tony Blair are somewhat close together inside of the World news cluster. Interestingly, although the 5 nearest neighbors (red) were closest in high dimensional space, they are not the closest points in this compressed 2D space. Compressing the embeddings down to 2 dimensions discards much of their information, and the nearest neighbors in the 2D space don't seem to be as relevant as those in the full embedding space.


```python
# a 2D chart of nearest neighbors of the chipset security article
chart_from_components(
    components=tsne_components,
    labels=chipset_security_labels,
    strings=article_descriptions,
    width=600,
    height=500,
    title="Nearest neighbors of the chipset security article",
    category_orders={"label": ["Other", "Nearest neighbor (top 5)", "Source"]},
)

```



For the chipset security example, the 4 closest nearest neighbors in the full embedding space remain nearest neighbors in this compressed 2D visualization. The fifth is displayed as more distant, despite being closer in the full embedding space.

Should you want to, you can also make an interactive 3D plot of the embeddings with the function `chart_from_components_3D`. (Doing so will require recomputing the t-SNE components with `n_components=3`.)

# Batch processing with the Batch API

The new Batch API allows to **create async batch jobs for a lower price and with higher rate limits**.

Batches will be completed within 24h, but may be processed sooner depending on global usage. 

Ideal use cases for the Batch API include:

- Tagging, captioning, or enriching content on a marketplace or blog
- Categorizing and suggesting answers for support tickets
- Performing sentiment analysis on large datasets of customer feedback
- Generating summaries or translations for collections of documents or articles

and much more!

This cookbook will walk you through how to use the Batch API with a couple of practical examples.

We will start with an example to categorize movies using `gpt-4o-mini`, and then cover how we can use the vision capabilities of this model to caption images.

Please note that multiple models are available through the Batch API, and that you can use the same parameters in your Batch API calls as with the Chat Completions endpoint.

## Setup


```python
# Make sure you have the latest version of the SDK available to use the Batch API
%pip install openai --upgrade
```


```python
import json
from openai import OpenAI
import pandas as pd
from IPython.display import Image, display
```


```python
# Initializing OpenAI client - see https://platform.openai.com/docs/quickstart?context=python
client = OpenAI()
```

## First example: Categorizing movies

In this example, we will use `gpt-4o-mini` to extract movie categories from a description of the movie. We will also extract a 1-sentence summary from this description. 

We will use [JSON mode](https://platform.openai.com/docs/guides/text-generation/json-mode) to extract categories as an array of strings and the 1-sentence summary in a structured format. 

For each movie, we want to get a result that looks like this:

```
{
    categories: ['category1', 'category2', 'category3'],
    summary: '1-sentence summary'
}
```

### Loading data

We will use the IMDB top 1000 movies dataset for this example. 


```python
dataset_path = "data/imdb_top_1000.csv"

df = pd.read_csv(dataset_path)
df.head()
```

### Creating the batch file

The batch file, in the `jsonl` format, should contain one line (json object) per request.
Each request is defined as such:

```
{
    "custom_id": <REQUEST_ID>,
    "method": "POST",
    "url": "/v1/chat/completions",
    "body": {
        "model": <MODEL>,
        "messages": <MESSAGES>,
        // other parameters
    }
}
```

Note: the request ID should be unique per batch. This is what you can use to match results to the initial input files, as requests will not be returned in the same order.


```python
# Creating an array of json tasks

tasks = []

for index, row in df.iterrows():
    
    description = row['Overview']
    
    task = {
        "custom_id": f"task-{index}",
        "method": "POST",
        "url": "/v1/chat/completions",
        "body": {
            # This is what you would have in your Chat Completions API call
            "model": "gpt-4o-mini",
            "temperature": 0.1,
            "response_format": { 
                "type": "json_object"
            },
            "messages": [
                {
                    "role": "system",
                    "content": categorize_system_prompt
                },
                {
                    "role": "user",
                    "content": description
                }
            ],
        }
    }
    
    tasks.append(task)
```


```python
# Creating the file

file_name = "data/batch_tasks_movies.jsonl"

with open(file_name, 'w') as file:
    for obj in tasks:
        file.write(json.dumps(obj) + '\n')
```

### Uploading the file


```python
batch_file = client.files.create(
  file=open(file_name, "rb"),
  purpose="batch"
)
```


```python
print(batch_file)
```

    FileObject(id='file-lx16f1KyIxQ2UHVvkG3HLfNR', bytes=1127310, created_at=1721144107, filename='batch_tasks_movies.jsonl', object='file', purpose='batch', status='processed', status_details=None)


### Creating the batch job


```python
batch_job = client.batches.create(
  input_file_id=batch_file.id,
  endpoint="/v1/chat/completions",
  completion_window="24h"
)
```

### Checking batch status

Note: this can take up to 24h, but it will usually be completed faster.

You can continue checking until the status is 'completed'.


```python
batch_job = client.batches.retrieve(batch_job.id)
print(batch_job)
```

### Retrieving results


```python
result_file_id = batch_job.output_file_id
result = client.files.content(result_file_id).content
```


```python
result_file_name = "data/batch_job_results_movies.jsonl"

with open(result_file_name, 'wb') as file:
    file.write(result)
```


```python
# Loading data from saved file
results = []
with open(result_file_name, 'r') as file:
    for line in file:
        # Parsing the JSON string into a dict and appending to the list of results
        json_object = json.loads(line.strip())
        results.append(json_object)
```

### Reading results
Reminder: the results are not in the same order as in the input file.
Make sure to check the custom_id to match the results against the input requests

## Second example: Captioning images

In this example, we will use `gpt-4-turbo` to caption images of furniture items. 

We will use the vision capabilities of the model to analyze the images and generate the captions.

### Loading data

We will use the Amazon furniture dataset for this example.


```python
dataset_path = "data/amazon_furniture_dataset.csv"
df = pd.read_csv(dataset_path)
df.head()

Your goal is to generate short, descriptive captions for images of items.
You will be provided with an item image and the name of that item and you will output a caption that captures the most important information about the item.
If there are multiple items depicted, refer to the name provided to understand which item you should describe.
Your generated caption should be short (1 sentence), and include only the most important information about the item.

Your goal is to generate short, descriptive captions for images of items.
You will be provided with an item image and the name of that item and you will output a caption that captures the most important information about the item.
If there are multiple items depicted, refer to the name provided to understand which item you should describe.
Your generated caption should be short (1 sentence), and include only the most important information about the item.
The most important information could be: the type of item, the style (if mentioned), the material or color if especially relevant and/or any distinctive features.
Keep it short and to the point.

```python

    for line in file:
        # Parsing the JSON string into a dict and appending to the list of results
        json_object = json.loads(line.strip())
        results.append(json_object)
```


```python
# Reading only the first results

## Wrapping up

In this cookbook, we have seen two examples of how to use the new Batch API, but keep in mind that the Batch API works the same way as the Chat Completions endpoint, supporting the same parameters and most of the recent models (gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-3.5-turbo...).

By using this API, you can significantly reduce costs, so we recommend switching every workload that can happen async to a batch job with this new API.

# How to fine-tune chat models

Fine-tuning improves the model by training on many more examples than can fit in a prompt, letting you achieve better results on a wide number of tasks. This notebook provides a step-by-step guide for our new GPT-4o mini fine-tuning. We'll perform entity extraction using the [RecipeNLG dataset](https://github.com/Glorf/recipenlg), which provides various recipes and a list of extracted generic ingredients for each. This is a common dataset for named entity recognition (NER) tasks.

Note: **GPT-4o mini fine-tuning is available to developers in our [Tier 4 and 5 usage tiers](https://platform.openai.com/docs/guides/rate-limits/usage-tiers).** You can start fine-tuning GPT-4o mini by visiting your fine-tuning dashboard, clicking "create", and selecting “gpt-4o-mini-2024-07-18” from the base model drop-down.

We will go through the following steps:

1. **Setup:** Loading our dataset and filtering down to one domain to fine-tune on.
2. **Data preparation:** Preparing your data for fine-tuning by creating training and validation examples, and uploading them to the `Files` endpoint.
3. **Fine-tuning:** Creating your fine-tuned model.
4. **Inference:** Using your fine-tuned model for inference on new inputs.

By the end of this you should be able to train, evaluate and deploy a fine-tuned `gpt-4o-mini-2024-07-18` model.

For more information on fine-tuning, you can refer to our [documentation guide](https://platform.openai.com/docs/guides/fine-tuning) or [API reference](https://platform.openai.com/docs/api-reference/fine-tuning).


## Setup



```python
# make sure to use the latest version of the openai python package
!pip install --upgrade --quiet openai
```


```python
import json
import openai
import os
import pandas as pd
from pprint import pprint

client = openai.OpenAI(
    api_key=os.environ.get("OPENAI_API_KEY"),
    organization="<org id>",
    project="<project id>",
)
```

Fine-tuning works best when focused on a particular domain. It's important to make sure your dataset is both focused enough for the model to learn, but general enough that unseen examples won't be missed. Having this in mind, we have extracted a subset from the RecipesNLG dataset to only contain documents from [cookbooks.com](https://cookbooks.com/).



```python
# Read in the dataset we'll use for this task.
# This will be the RecipesNLG dataset, which we've cleaned to only contain documents from www.cookbooks.com
recipe_df = pd.read_csv("data/cookbook_recipes_nlg_10k.csv")

recipe_df.head()
```

## Data preparation

We'll begin by preparing our data. When fine-tuning with the `ChatCompletion` format, each training example is a simple list of `messages`. For example, an entry could look like:

```
[{'role': 'system',
  'content': 'You are a helpful recipe assistant. You are to extract the generic ingredients from each of the recipes provided.'},

 {'role': 'user',
  'content': 'Title: No-Bake Nut Cookies\n\nIngredients: ["1 c. firmly packed brown sugar", "1/2 c. evaporated milk", "1/2 tsp. vanilla", "1/2 c. broken nuts (pecans)", "2 Tbsp. butter or margarine", "3 1/2 c. bite size shredded rice biscuits"]\n\nGeneric ingredients: '},

 {'role': 'assistant',
  'content': '["brown sugar", "milk", "vanilla", "nuts", "butter", "bite size shredded rice biscuits"]'}]
```

During the training process this conversation will be split, with the final entry being the `completion` that the model will produce, and the remainder of the `messages` acting as the prompt. Consider this when building your training examples - if your model will act on multi-turn conversations, then please provide representative examples so it doesn't perform poorly when the conversation starts to expand.

Please note that currently there is a 4096 token limit for each training example. Anything longer than this will be truncated at 4096 tokens.

system_message = "You are a helpful recipe assistant. You are to extract the generic ingredients from each of the recipes provided."

Let's now do this for a subset of the dataset to use as our training data. You can begin with even 30-50 well-pruned examples. You should see performance continue to scale linearly as you increase the size of the training set, but your jobs will also take longer.



```python
# use the first 100 rows of the dataset for training
training_df = recipe_df.loc[0:100]

# apply the prepare_example_conversation function to each row of the training_df
training_data = training_df.apply(prepare_example_conversation, axis=1).tolist()

for example in training_data[:5]:
    print(example)
```

In addition to training data, we can also **optionally** provide validation data, which will be used to make sure that the model does not overfit your training set.



```python
validation_df = recipe_df.loc[101:200]
validation_data = validation_df.apply(
    prepare_example_conversation, axis=1).tolist()
```

We then need to save our data as `.jsonl` files, with each line being one training example conversation.



```python
def write_jsonl(data_list: list, filename: str) -> None:
    with open(filename, "w") as out:
        for ddict in data_list:
            jout = json.dumps(ddict) + "\n"
            out.write(jout)
```
