DescriptionEnables LLMs to invoke external functions by generating structured JSON arguments matching defined schemas. Supports parallel function calls, error handling, and chained invocations for complex multi-step tool interactions.Guides LLMs to produce step-by-step reasoning before arriving at a final answer. Dramatically improves performance on math, logic, and multi-step problems by making the model's reasoning process explicit and verifiable.
