How do you implement function calling with the OpenAI API?
Function calling allows the model to output structured JSON to call your functions. Define tools: [{type: "function", function: {name: "get_weather", description: "...", parameters: {type: "object", properties: {...}}}}]. Send to API with tools parameter. If response.choices[0].message.tool_calls exists, execute the function and send results back as a tool message. This is the basis of all LLM agents and structured output workflows.
