Nexus Raven is a 13 billion parameter model designed for function calling tasks.

Updated to NexusRaven-V2, this model is an updated open-source and commercially viable function calling model:

• Versatile Function Calling Capability: capable of generating single function calls, nested calls, and parallel calls in many challenging cases.
• Fully Explainable: capable of generating very detailed explanations for the function calls it generates. This behavior can be turned off, to save tokens during inference.
• Performance Highlights: surpasses GPT-4 by up to 7% in function calling success rates in human-generated use cases involving nested and composite functions.
• Generalization to the Unseen: has never been trained on the functions used in evaluation.
• Commercially Permissive: The training does not involve any data generated by proprietary LLMs such as GPT-4. You have full control of the model when deployed in commercial applications.

Example prompt

Function:
def get_weather_data(coordinates):
    """
    Fetches weather data from the Open-Meteo API for the given latitude and longitude.

    Args:
    coordinates (tuple): The latitude of the location.

    Returns:
    float: The current temperature in the coordinates you've asked for
    """

Function:
def get_coordinates_from_city(city_name):
    """
    Fetches the latitude and longitude of a given city name using the Maps.co Geocoding API.

    Args:
    city_name (str): The name of the city.

    Returns:
    tuple: The latitude and longitude of the city.
    """

User Query: {query}<human_end>

This will generate a response similar to:

Call: get_weather_data(coordinates=get_coordinates_from_city(city_name='Seattle'))<bot_end>
Thought: The function call `get_weather_data(coordinates=get_coordinates_from_city(city_name='Seattle'))` answers the question "What's the weather like in Seattle right now?" by following these steps:

1. `get_coordinates_from_city(city_name='Seattle')`: This function call fetches the latitude and longitude of the city "Seattle" using the Maps.co Geocoding API.
2. `get_weather_data(coordinates=...)`: This function call fetches the current weather data for the coordinates returned by the previous function call.

Therefore, the function call `get_weather_data(coordinates=get_coordinates_from_city(city_name='Seattle'))` answers the question "What's the weather like in Seattle right now?" by first fetching the coordinates of the city "Seattle" and then fetching the current weather data for those coordinates.
