Introduction

Gorilla OpenFunctions extends Large Language Model(LLM) Chat Completion feature to formulate executable APIs call given natural language instructions and API context.

Models Available

Example Usage (Hosted)

1. OpenFunctions is compatible with OpenAI Functions

!pip install openai==0.28.1

2. Point to Gorilla hosted servers

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-v0",
      temperature=0.0,
      messages=[{"role": "user", "content": prompt}],
      functions=functions,
    )
    return completion.choices[0].message.content
  except Exception as e:
    print(e, model, prompt)

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

query = "Call me an Uber ride type \"Plus\" in Berkeley at zipcode 94704 in 10 minutes"
functions = [
    {
        "name": "Uber Carpool",
        "api_name": "uber.ride",
        "description": "Find suitable ride for customers given the location, type of ride, and the amount of time the customer is willing to wait as parameters",
        "parameters":  [{"name": "loc", "description": "location of the starting place of the uber ride"}, {"name":"type", "enum": ["plus", "comfort", "black"], "description": "types of uber ride user is ordering"}, {"name": "time", "description": "the amount of time in minutes the customer is willing to wait"}]
    }
]
get_gorilla_response(query, functions=functions)

4. Expected output

uber.ride(loc="berkeley", type="plus", time=10)

Example Usage (Run Locally)

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.
