watt-tool-8B

watt-tool-8B is a fine-tuned language model based on LLaMa-3.1-8B-Instruct, optimized for tool usage and multi-turn dialogue. It achieves state-of-the-art performance on the Berkeley Function-Calling Leaderboard (BFCL).

Model Description

This model is specifically designed to excel at complex tool usage scenarios that require multi-turn interactions, making it ideal for empowering platforms like Lupan, an AI-powered workflow building tool. By leveraging a carefully curated and optimized dataset, watt-tool-8B demonstrates superior capabilities in understanding user requests, selecting appropriate tools, and effectively utilizing them across multiple turns of conversation.

Target Application: AI Workflow Building as in https://lupan.watt.chat/ and Coze.

Key Features

Enhanced Tool Usage: Fine-tuned for precise and efficient tool selection and execution.
Multi-Turn Dialogue: Optimized for maintaining context and effectively utilizing tools across multiple turns of conversation, enabling more complex task completion.
State-of-the-Art Performance: Achieves top performance on the BFCL, demonstrating its capabilities in function calling and tool usage.

Training Methodology

watt-tool-8B is trained using supervised fine-tuning on a specialized dataset designed for tool usage and multi-turn dialogue. We use CoT techniques to synthesize high-quality multi-turn dialogue data.

The training process is inspired by the principles outlined in the paper: "Direct Multi-Turn Preference Optimization for Language Agents". We use SFT and DMPO to further enhance the model's performance in multi-turn agent tasks.

How to Use

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "watt-ai/watt-tool-8B"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype='auto', device_map="auto")

# Example usage (adapt as needed for your specific tool usage scenario)
"""You are an expert in composing functions. You are given a question and a set of possible functions. Based on the question, you will need to make one or more function/tool calls to achieve the purpose.
If none of the function can be used, point it out. If the given question lacks the parameters required by the function, also point it out.
You should only return the function call in tools call sections.

If you decide to invoke any of the function(s), you MUST put it in the format of [func_name1(params_name1=params_value1, params_name2=params_value2...), func_name2(params)]
You SHOULD NOT include any other text in the response.
Here is a list of functions in JSON format that you can invoke.\n{functions}\n
