Structured Output and Function Calling
For developers who need model output that code can use directly, and models that can call real APIs and databases safely. You will learn to get schema-valid JSON from current model APIs, build a tool-calling loop, and put validation, authorisation and limits between the model and anything it can change.
Course Content
Learn why free text breaks pipelines, what JSON mode and schema-constrained output actually guarantee, and how function calling lets a model request real actions.
Connect a model to external APIs and databases with bounded, shaped results, and put the permission, validation and limit checks in place that keep tool calls safe.
Build a multi-turn weather assistant with two tools, a correct tool-calling loop, argument validation, caching and tests that need no network.
