Nexus Raven 13B: A Breakthrough in Function Calling AI Models

Nexus Raven is a sophisticated AI language model boasting 13 billion parameters specifically optimized for function calling tasks. The model has been updated to NexusRaven-V2, making it not only an advanced open-source solution but also commercially viable for various applications. This article will delve into its remarkable features and capabilities, along with how it stands out in the competitive landscape of AI models.

Key Features of Nexus Raven 13B

• Versatile Function Calling Capability: Nexus Raven can generate single function calls, nested calls, and even parallel calls, excelling in complex scenarios.
• Fully Explainable: The model can produce comprehensive explanations for the function calls it generates, enhancing user understanding. This feature can be disabled to conserve tokens during inference.
• Performance Highlights: Nexus Raven surpasses existing models, including GPT-4, by achieving up to 7% higher success rates in function calling accuracy, particularly in human-generated cases with nested and composite functions.
• Generalization to the Unseen: The model demonstrates exceptional generalization capabilities, having been evaluated on functions it has never encountered during training.
• Commercially Permissive: Nexus Raven ensures that its training data does not include outputs from proprietary LLMs, granting users complete control for commercial deployments.

Example Prompt and Functionality

To illustrate the powerful features of Nexus Raven, consider the following example involving function definitions:

Function:
def get_exchange_rate(from_currency, to_currency):
    """
    Fetches the current exchange rate from one currency to another using the Exchange Rates API.
    Args:
    from_currency (str): The currency code to convert from (e.g., 'USD').
    to_currency (str): The currency code to convert to (e.g., 'EUR').
    Returns:
    float: The current exchange rate from the from_currency to the to_currency.
    """
    
Function:
def get_currency_code(country_name):
    """
    Fetches the currency code (ISO 4217) for a given country using the Rest Countries API.
    Args:
    country_name (str): The name of the country.
    Returns:
    str: The currency code of the country.
    """
