+# ToolACE-2-Llama-3.1-8B
+
+ToolACE-2-Llama-3.1-8B is a fine-tuned model of LLaMA-3.1-8B-Instruct with our dataset [ToolACE](https://huggingface.co/datasets/Team-ACE/ToolACE) tailored for tool usage. 
+Compared with [ToolACE-8B](https://huggingface.co/Team-ACE/ToolACE-8B), ToolACE-2-8B enhances the tool-usage ability by self-refinment tuning and task decomposition. 
+ToolACE-2-Llama-3.1-8B achieves a state-of-the-art performance on the [Berkeley Function-Calling Leaderboard(BFCL)](https://gorilla.cs.berkeley.edu/leaderboard.html#leaderboard), rivaling the latest GPT-4 models. 
+
+
+ToolACE is an automatic agentic pipeline designed to generate **A**ccurate, **C**omplex, and div**E**rse tool-learning data. 
+ToolACE leverages a novel self-evolution synthesis process to curate a comprehensive API pool of 26,507 diverse APIs. 
+Dialogs are further generated through the interplay among multiple agents, guided by a formalized thinking process. 
+To ensure data accuracy, we implement a dual-layer verification system combining rule-based and model-based checks. 
+More details can be found in our paper on arxiv:  [*ToolACE: Winning the Points of LLM Function Calling*](https://arxiv.org/abs/2409.00920)

+
+Here are the winning scores of ToolACE-2-8B in [BFCL-v3]((https://gorilla.cs.berkeley.edu/leaderboard.html#leaderboard)), which wins the highest scores among 8B-scale models.

+
+### Usage
+Here we provide a code snippet with `apply_chat_template` to show you how to load the tokenizer and model and how to generate function calling with given functions.
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_name = "Team-ACE/ToolACE-2-Llama-3.1-8B"
+
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForCausalLM.from_pretrained(
+    model_name,
+    torch_dtype='auto',
+    device_map='auto'
+)
+
+
+# You can modify the prompt for your task
+system_prompt = """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
+"""
+
+# User query
+query = "Find me the sales growth rate for company XYZ for the last 3 years and also the interest coverage ratio for the same duration."
+
+# Availabel tools in JSON format (OpenAI-format)
+tools = [

+            },
+            "required": ["location", "days"]
+        }
+    }
+]
+
+messages = [
+    {'role': 'system', 'content': system_prompt.format(functions=tools)},
+    {'role': 'user', 'content': query}
+]
+
+inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
+
+outputs = model.generate(inputs, max_new_tokens=512, do_sample=False, num_return_sequences=1, eos_token_id=tokenizer.eos_token_id)
+print(tokenizer.decode(outputs[0][len(inputs[0]):], skip_special_tokens=True))
+```
+
+Then you should be able to see the following output functional calls:
+```
+[sales_growth.calculate(company="XYZ", years=3), financial_ratios.interest_coverage(company_name="XYZ", years=3)]
+```
