Gorilla OpenFunctions v2

💡 SoTA for open-source models. On-par with GPT-4.

🚀 Check out the Berkeley Function Calling Leaderboard
📣 Read more in our OpenFunctions v2 release blog

Introduction

Gorilla OpenFunctions extends Large Language Model(LLM) Chat Completion feature to formulate executable APIs call given natural language instructions and API context. With OpenFunctions v2, we now support:

Multiple functions - choose betwen functions
Parallel functions - call the same function N time with different parameter values
Multiple & parallel - both of the above in a single chatcompletion call (one generation)
Relevance detection - when chatting, chat. When asked for function, returns a function
Python - supports string, number, boolean, list, tuple, dict parameter datatypes and Any for those not natively supported.
JAVA - support for byte, short, int, float, double, long, boolean, char, Array, ArrayList, Set, HashMap, Hashtable, Queue, Stack, and Any datatypes.
JavaScript - support for String, Number, Bigint, Boolean, dict (object), Array, Date, and Any datatypes.
REST - native REST support

Training

Gorilla Openfunctions v2 is a 7B parameter model, and is built on top of the deepseek coder LLM. Check out openfunctions-v2 blog to learn more about the data composition and some insights into the training process.

Example Usage (Hosted)

OpenFunctions is compatible with OpenAI Functions

!pip install openai==0.28.1

Point to Gorilla hosted servers

python

import openai

def get_gorilla_response(prompt="Call me an Uber ride type \"Plus\" in Berkeley at zipcode 94704 in 10 minutes", model="gorilla-openfunctions-v0", functions=[]):
  openai.api_key = "EMPTY"
  openai.api_base = "http://luigi.millennium.berkeley.edu:8000/v1"
  try:
    completion = openai.ChatCompletion.create(
      model="gorilla-openfunctions-v2",
      temperature=0.0,
      messages=[{"role": "user", "content": prompt}],
      functions=functions,
    )
    return completion.choices[0]
  except Exception as e:
    print(e, model, prompt)

Pass the user argument and set of functions, Gorilla OpenFunctions returns a fully formatted json

python

query = "What's the weather like in the two cities of Boston and San Francisco?"
functions = [
    {
        "name": "get_current_weather",
        "description": "Get the current weather in a given location",
        "parameters": {
            "type": "object",
            "properties": {
                "location": {
                    "type": "string",
                    "description": "The city and state, e.g. San Francisco, CA",
                },
                "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]},
            },
            "required": ["location"],
        },
    }
]
get_gorilla_response(query, functions=functions)

Expected output NEW

Gorilla returns a readily accessible string AND Open-AI compatible JSON.

python

{
  "index": 0,
  "message": {
    "role": "assistant",
    "content": "get_current_weather(location='Boston, MA'), get_current_weather(location='San Francisco, CA')",
    "function_call": [
      {
        "name": "get_current_weather",
        "arguments": {
          "location": "Boston, MA"
        }
      },
      {
        "name": "get_current_weather",
        "arguments": {
          "location": "San Francisco, CA"
        }
      }
    ]
  },
  "finish_reason": "stop"
}

We have retained the string functionality that our community loved from OpenFunctions v1 get_current_weather(location='Boston, MA'), get_current_weather(location='San Francisco, CA') above. And Notice the function_call key in the JSON to be OpenAI compatible.

This is possible in OpenFunctions v2, because we ensure that the output includes the name of the argument and not just the value. This enables us to parse the output into a JSON. In those scenarios where the output is not parsable into JSON, we will always return the function call string.

End to End Example

Run the example code in [ofv2_hosted.py](https://github.com/ShishirPatil/gorilla/tree/main/openfunctions) to see how the model works.

python ofv2_hosted.py

Expected Output:

bash

(.py3) shishir@dhcp-132-64:~/Work/Gorilla/openfunctions/$ python ofv2_hosted.py
--------------------
Function call strings(s): get_current_weather(location='Boston, MA'), get_current_weather(location='San Francisco, CA')
--------------------
OpenAI compatible `function_call`: [<OpenAIObject at 0x1139ba890> JSON: 
{
  "name": "get_current_weather",
  "arguments": 
  {
    "location": "Boston, MA"
  }
}, <OpenAIObject at 0x1139ba930> JSON: {
  "name": "get_current_weather",
  "arguments": 
  {
    "location": "San Francisco, CA"
  }
}]

Running OpenFunctions Locally

If you want to Run OpenFunctions locally, here is the prompt format that we used:

python

def get_prompt(user_query: str, functions: list = []) -> str:
    """
    Generates a conversation prompt based on the user's query and a list of functions.

    Parameters:
    - user_query (str): The user's query.
    - functions (list): A list of functions to include in the prompt.

    Returns:
    - str: The formatted conversation prompt.
    """
    system = "You are an AI programming assistant, utilizing the Gorilla LLM model, developed by Gorilla LLM, and you only answer questions related to computer science. For politically sensitive questions, security and privacy issues, and other non-computer science questions, you will refuse to answer."
    if len(functions) == 0:
        return f"{system}\n### Instruction: <<question>> {user_query}\n### Response: "
    functions_string = json.dumps(functions)
    return f"{system}\n### Instruction: <<function>>{functions_string}\n<<question>>{user_query}\### Response: "

Further, here is how we format the response:

Install the dependencies with:

bash

pip3 install tree_sitter
git clone https://github.com/tree-sitter/tree-sitter-java.git
git clone https://github.com/tree-sitter/tree-sitter-javascript.git

And you can use the following code to format the response:

python

from openfunctions_utils import strip_function_calls, parse_function_call

def format_response(response: str):
    """
    Formats the response from the OpenFunctions model.

    Parameters:
    - response (str): The response generated by the LLM.

    Returns:
    - str: The formatted response.
    - dict: The function call(s) extracted from the response.

    """
    function_call_dicts = None
    try:
        response = strip_function_calls(response)
        # Parallel function calls returned as a str, list[dict]
        if len(response) > 1: 
            function_call_dicts = []
            for function_call in response:
                function_call_dicts.append(parse_function_call(function_call))
            response = ", ".join(response)
        # Single function call returned as a str, dict
        else:
            function_call_dicts = parse_function_call(response[0])
            response = response[0]
    except Exception as e:
        # Just faithfully return the generated response str to the user
        pass
    return response, function_call_dicts
        

Note: Use the get_prompt and format_response only if you are hosting it Locally. If you are using the Berkeley hosted models through the Chat-completion API, we do this in the backend, so you don't have to do this. The model is supported in Hugging Face 🤗 Transformers and can be run up locally:
