# Build AI Applications

Build and deploy ambitious AI applications to Cloudflare's global network.

Diagrams, design patterns, and detailed best practices to help you generate solutions with Cloudflare products.

- Content-based asset creation : Combining text-generation models with text-to-image models can lead to powerful AI systems capable of generating visual content based on input prompts. This integration can be achieved through a collaborative framework where a text-generation model generates prompts for the text-to-image model based on input text.
- Composable AI architecture : The architecture diagram illustrates how AI applications can be built end-to-end on Cloudflare, or single services can be integrated with external infrastructure and services.
- Multi-vendor AI observability and control : By shifting features such as rate limiting, caching, and error handling to the proxy layer, organizations can apply unified configurations across services and inference service providers.
- Retrieval Augmented Generation (RAG) : Retrieval-Augmented Generation (RAG) is an innovative approach in natural language processing that integrates retrieval mechanisms with generative models to enhance text generation.
- Automatic captioning for video uploads : By integrating automatic speech recognition technology into video platforms, content creators, publishers, and distributors can reach a broader audience, including individuals with hearing impairments or those who prefer to consume content in different languages.
- Ingesting BigQuery Data into Workers AI : You can connect a Cloudflare Worker to get data from Google BigQuery and pass it to Workers AI, to run AI Models, powered by serverless GPUs. This will allow you to enhance data with AI-generated responses, such as detecting the sentiment score of some text or generating tags for an article. This document describes a simple way to get started if you are looking to give Workers AI a try and see how the new and different AI models would perform with your data hosted in BigQuery.

- Gamertown Customer Support Assistant: A RAG based AI Chat app that uses Vectorize to access video game data for employees of Gamertown.
- LoRA News Summarizer: This application uses Cloudflare Workers AI, Streamlit, and Beautiful Soup to summarize input news article URLs in a variety of tones.
- shrty.dev: A URL shortener that makes use of KV and Workers Analytics Engine. The admin interface uses Function Calling. Go Shorty!

Step-by-step guides to help you build and learn.

- Deploy a Worker that connects to OpenAI via AI Gateway : In this tutorial, you will learn how to deploy a Worker that makes calls to OpenAI through AI Gateway. AI Gateway helps you better observe and control your AI applications with more analytics, caching, rate limiting, and logging.
- Recommend products on e-commerce sites using Workers AI and Stripe : E-commerce and media sites often work on increasing the average transaction value to boost profitability. One of the strategies to increase the average transaction value is "cross-selling," which involves recommending related products. Cloudflare offers a range of products designed to build mechanisms for retrieving data related to the products users are viewing or requesting. In this tutorial, you will experience developing functionalities necessary for cross-selling by creating APIs for related product searches and product recommendations.
