Nexus Raven 是一個 130 億參數的模型，專為函數呼叫任務而設計。

此模型已更新至 NexusRaven-V2，是一個更新的開源且商業上可行的函數呼叫模型

• 多功能函數呼叫能力：能夠在許多具挑戰性的情況下生成單個函數呼叫、巢狀呼叫和平行呼叫。
• 完全可解釋：能夠為其生成的函數呼叫生成非常詳細的解釋。此行為可以關閉，以在推論期間節省 tokens。
• 效能亮點：在涉及巢狀和複合函數的人工生成用例中，函數呼叫成功率超越 GPT-4 高達 7%。
• 推廣到未見：從未在評估中使用的函數上進行訓練。
• 商業上許可：訓練不涉及任何由專有 LLM（如 GPT-4）生成的數據。當模型部署在商業應用程式中時，您擁有完全的控制權。

範例提示

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>

這將產生類似於以下的響應

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.
