LLM Tool Calling: How It Works and How To Implement It

Large Language Models (LLMs) are key tools for cognitive tasks but lack the ability to interact with the external world. The invocation of LLM tools shifts from passive text generation to active participation in systems, enhancing the effectiveness of chatbots. The main challenge lies in establishing necessary security and monitoring mechanisms to ensure the success of these invocations in production environments. Invoking LLM tools functions as a mechanism that allows the model to create structured requests, often in JSON format, to call external functions or APIs.
