Welcome to the xLAM model family! Large Action Models (LAMs) are advanced large language models designed to enhance decision-making and translate user intentions into executable actions that interact with the world. LAMs autonomously plan and execute tasks to achieve specific goals, serving as the brains of AI agents. They have the potential to automate workflow processes across various domains, making them invaluable for a wide range of applications. The model release is exclusively for research purposes. A new and enhanced version of xLAM will soon be available exclusively to customers on our Platform.

Model Series

We provide a series of xLAMs in different sizes to cater to various applications, including those optimized for function-calling and general agent applications:

For our Function-calling series (more details are included at here), we also provide their quantized GGUF files for efficient deployment and execution. GGUF is a file format designed to efficiently store and load large language models, making GGUF ideal for running AI models on local devices with limited resources, enabling offline functionality and enhanced privacy.

For more details, check our GitHub and paper.

Repository Overview

This repository is about the general tool use series. For more specialized function calling models, please take a look into our fc series here.

The instructions will guide you through the setup, usage, and integration of our model series with HuggingFace.

Framework Versions

• Transformers 4.41.0
• Pytorch 2.3.0+cu121
• Datasets 2.19.1
• Tokenizers 0.19.1

Usage

Basic Usage with Huggingface

To use the model from Huggingface, please first install the transformers library:

pip install transformers>=4.41.0

Please note that, our model works best with our provided prompt format. It allows us to extract JSON output that is similar to the function-calling mode of ChatGPT.

We use the following example to illustrate how to use our model for 1) single-turn use case, and 2) multi-turn use case

1. Single-turn use case

import json
import torch 
from transformers import AutoModelForCausalLM, AutoTokenizer

torch.random.manual_seed(0) 

model_name = "Salesforce/xLAM-7b-r"
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", torch_dtype="auto", trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(model_name) 

# Please use our provided instruction prompt for best performance
task_instruction = """
Based on the previous context and API request history, generate an API request or a response as an AI assistant.""".strip()

format_instruction = """
The output should be of the JSON format, which specifies a list of generated function calls. The example format is as follows, please make sure the parameter type is correct. If no function call is needed, please make 
tool_calls an empty list "[]".
```

```
""".strip()

# Define the input query and available tools
query = "What's the weather like in New York in fahrenheit?"

get_weather_api = {
    "name": "get_weather",
    "description": "Get the current weather for a location",
    "parameters": {
        "type": "object",
        "properties": {
            "location": {
                "type": "string",
                "description": "The city and state, e.g. San Francisco, New York"
            },
            "unit": {
                "type": "string",

        },
        "required": ["query"]
    }
}

openai_format_tools = [get_weather_api, search_api]

# Helper function to convert openai format tools to our more concise xLAM format
def convert_to_xlam_tool(tools):
    ''''''
    if isinstance(tools, dict):
        return {
            "name": tools["name"],
            "description": tools["description"],
            "parameters": {k: v for k, v in tools["parameters"].get("properties", {}).items()}

    elif isinstance(tools, list):
        return [convert_to_xlam_tool(tool) for tool in tools]

def build_conversation_history_prompt(conversation_history: str):
    parsed_history = []
    for step_data in conversation_history:
        parsed_history.append({
            "step_id": step_data["step_id"],
            "thought": step_data["thought"],
            "tool_calls": step_data["tool_calls"],
            "next_observation": step_data["next_observation"],
            "user_input": step_data['user_input']
        })

conversation_history = []
content = build_prompt(task_instruction, format_instruction, xlam_format_tools, query, conversation_history)

messages=[
    { 'role': 'user', 'content': content}
]

inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)

# tokenizer.eos_token_id is the id of <|EOT|> token
outputs = model.generate(inputs, max_new_tokens=512, do_sample=False, num_return_sequences=1, eos_token_id=tokenizer.eos_token_id)
agent_action = tokenizer.decode(outputs[0][len(inputs[0]):], skip_special_tokens=True)

Then you should be able to see the following output string in JSON format:

{"thought": "I need to get the current weather for New York in fahrenheit.", "tool_calls": [{"name": "get_weather", "arguments": {"location": "New York", "unit": "fahrenheit"}}]}

2. Multi-turn use case

We also support multi-turn interaction with our model series. Here is the example of next round of interaction from the above example:

def parse_agent_action(agent_action: str):
    """
    Given an agent's action, parse it to add to conversation history
    """
    try: parsed_agent_action_json = json.loads(agent_action)
    except: return "", []
    
    if "thought" not in parsed_agent_action_json.keys(): thought = ""
    else: thought = parsed_agent_action_json["thought"]
    
    if "tool_calls" not in parsed_agent_action_json.keys(): tool_calls = []
    else: tool_calls = parsed_agent_action_json["tool_calls"]
    
    return thought, tool_calls

def update_conversation_history(conversation_history: list, agent_action: str, environment_response: str, user_input: str):
    """
    Update the conversation history list based on the new agent_action, environment_response, and/or user_input
    """
    thought, tool_calls = parse_agent_action(agent_action)
    new_step_data = {
        "step_id": len(conversation_history) + 1,
        "thought": thought,
        "tool_calls": tool_calls,
        "step_id": len(conversation_history),
        "next_observation": environment_response,
        "user_input": user_input,
    }
    
    conversation_history.append(new_step_data)

def get_environment_response(agent_action: str):
    """
    Get the environment response for the agent_action
    """
    # TODO: add custom implementation here
    error_message, response_message = "", ""
    return {"error": error_message, "response": response_message}

# ------------- before here are the steps to get agent_response from the example above ----------

# 1. get the next state after agent's response:
#   The next 2 lines are examples of getting environment response and user_input.
#   It is depended on particular usage, we can have either one or both of those.
environment_response = get_environment_response(agent_action)
user_input = "Now, search on the Internet for cute puppies"

# 2. after we got environment_response and (or) user_input, we want to add to our conversation history
update_conversation_history(conversation_history, agent_action, environment_response, user_input)

# 3. we now can build the prompt
content = build_prompt(task_instruction, format_instruction, xlam_format_tools, query, conversation_history)

# 4. Now, we just retrieve the inputs for the LLM
messages=[
    { 'role': 'user', 'content': content}
]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)

# 5. Generate the outputs & decode
#   tokenizer.eos_token_id is the id of <|EOT|> token
outputs = model.generate(inputs, max_new_tokens=512, do_sample=False, num_return_sequences=1, eos_token_id=tokenizer.eos_token_id)
agent_action = tokenizer.decode(outputs[0][len(inputs[0]):], skip_special_tokens=True)

This would be the corresponding output:

{"thought": "I need to get the current weather for New York in fahrenheit.", "tool_calls": [{"name": "get_weather", "arguments": {"location": "New York", "unit": "fahrenheit"}}]}

We highly recommend to use our provided prompt format and helper functions to yield the best function-calling performance of our model.
