Keywords

💡LLM (Large Language Model)

A Large Language Model (LLM) refers to a type of artificial intelligence model that is trained on vast amounts of text data to generate human-like language. In the context of the video, the LLM is used for tool use or function calling, which allows the model to access real-time data or external information to enhance its responses. For example, the script discusses integrating an LLM with APIs to retrieve current market data or customer information.

💡Tool Use

Tool use in the video script pertains to the capability of a language model to interact with external tools or functions to fetch information or perform tasks. It is a technique that extends the model's functionality beyond its pre-trained knowledge. The script illustrates how tool use is implemented through structured metadata and function definitions, allowing the model to make informed decisions and provide more accurate responses.

💡Function Calling

Function calling is a process where a language model invokes a specific function to retrieve or compute data needed to answer a query. The script explains that function calling is a critical technique in tool use, allowing the model to access real-time information, such as weather updates, which the model would not inherently know without accessing an external data source.

💡API (Application Programming Interface)

An API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other. In the video script, APIs are used as a means for the LLM to access real-time data, such as market data or customer database information, which the model can then use to provide more accurate and relevant responses.

💡Metadata

Metadata in this context is structured data that describes the functions available to the language model. It provides information about the functions, such as their names, parameters, and descriptions, which the model uses to understand how to interact with these functions. The script emphasizes the importance of programmatically generating metadata from function definitions for consistency and reliability.

💡GPT-40 Mini

GPT-40 Mini is a reference to a specific model or version of a large language model that is mentioned in the script.
