Tool and Function Calling Explained
How models use tools without running anything themselves, with a clear walk-through of the request, the tool result and the final answer.
Tool calling is how an AI model reaches beyond its own text: checking the weather, looking up a customer, running a calculation. The surprising part is that the model never runs anything. It writes a polite request, your code does the work, and the model reads the result. Once you see this, agents, plugins and connectors all become easier to understand.
