# CoALM-405B: The Largest Open-Source Agentic LLM

[![Made with Oumi](https://badgen.net/badge/Made%20with/Oumi/%23085CFF?icon=https%3A%2F%2Foumi.ai%2Flogo_dark.svg)](https://github.com/oumi-ai/oumi)

## 🌟 Model Overview

**CoALM-405B** is the **largest fully open-source Conversational Agentic Language Model**. This model sets a new standard in **Conversational AI**, seamlessly integrating both **Task-Oriented Dialogue (TOD) capabilities** and **Language Agent (LA) functionalities**. 
It is designed to **push the boundaries** of open-source agentic LLMs, excelling at **multi-turn dialogue, tool usage, reasoning, and API execution**. It is the **best-performing fully open-source LLM** on the **Berkeley Function Calling Leaderboard V3 (BFCL V3)**, marking a leap in open-source AI research.

## ❗️ How to Use CoALM-405B
It requires 16xH100 NVIDIA GPUs for Inference.

### 🏗 How to Load the Model using HuggingFace
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("uiuc-convai/CoALM-8B")
model = AutoModelForCausalLM.from_pretrained("uiuc-convai/CoALM-8B")
```

### 🛠 Example Oumi Inference
Oumi multi-node inference support is under development. 
CoALM-405B likely requires multi-node inference as most single nodes support up to 640GB of GPU VRAM.
To run multi-node inference, we recommend [vLLM](https://docs.vllm.ai/en/latest/serving/distributed_serving.html).

### 🛠 Example Oumi Fine-Tuning
```bash
pip install oumi

# See oumi_train.yaml in this model's /oumi/ directory.
oumi train -c ./oumi_train.yaml
```

More fine-tuning and **community-driven** optimizations are planned to enhance real-world usability.
