# CoALM-8B: Conversational Agentic Language Model

[![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 Description
**CoALM-8B** is the smallest open-source model of **CoALM** (Conversational Agentic Language Model) series, designed to integrate both **Task-Oriented Dialogue (TOD) capabilities** and **Language Agent (LA) functionalities** into a unified system. By fine-tuning on **CoALM-IT**, a novel dataset that interleaves multi-turn ReAct-based reasoning with complex API usage, CoALM-8B achieves promising results on TOD and function-calling benchmarks.

CoALM-8B is trained on a **multi-task dataset** covering dialogue state tracking, function calling, and multi-turn reasoning. The model outperforms top domain-specific models on key evaluation benchmarks: **MultiWOZ 2.4 (TOD), BFCL V3 (LA), and API-Bank (LA).**

## Capabilities and Features

### 🗣 Conversational Agentic Abilities
- **Multi-turn Dialogue Mastery:** Maintains coherent conversations across multiple turns with accurate state tracking.
- **Function Calling and API Integration:** Dynamically selects and calls APIs for task execution.
- **ReAct-based Reasoning:** Utilizes a structured reasoning process (User-Thought-Action-Observation-Thought-Response).
- **Zero-Shot Generalization:** Excels in previously unseen function-calling tasks.

### 🚀 Benchmark Performance
- **MultiWOZ 2.4 (TOD):** Excels in dialogue state tracking and task completion.
- **BFCL V3 (LA):** Demonstrates superior function-calling abilities over language agents.
- **API-Bank (LA):** Accurately generates API calls and integrates responses into conversation flow.

2. **Function Calling Fine-tuning:** Trained to select and generate well-formed API calls from LA datasets.
3. **ReAct-based Fine-tuning:** Addresses multi-turn conversations with API integration using a structured reasoning framework.

## Usage
### 🏗 How to Load the Model using Transformers
```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
```bash
pip install oumi

# See oumi_infer.yaml in this model's /oumi/ directory.
oumi infer -i -c ./oumi_infer.yaml
```

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

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

---
- **Task-Specific Calibration:** While CoALM-8B generalizes well across tasks, performance can improve with domain-specific fine-tuning.
- **Scalability to Larger Models:** Future iterations (CoALM-70B, CoALM-405B) extend capabilities to larger-scale agentic conversations.
- **Open-Source Expansion:** All datasets, training scripts, and model checkpoints are publicly available to foster further research.
