/ quick answer

Tool Calling is the pattern where an LLM selects a predefined function, fills its arguments, and hands execution to software. It is the bridge between language reasoning and reliable system action. The model-to-system interface that lets an LLM trigger external actions.

The model-to-system interface that lets an LLM trigger external actions. Tool Calling is the pattern where an LLM selects a predefined function, fills its arguments, and hands execution to software. It is the bridge between language reasoning and reliable system action. In practice: A support assistant decides to call get_order_status with an order ID instead of guessing the delivery date from conversation context.
