Gorilla LLM

Gorilla LLM is an open-source large language model developed by researchers at UC Berkeley that is specifically trained and optimized for API function calling, enabling AI systems to accurately generate API calls for thousands of machine learning APIs, web services, and cloud functions from natural language instructions. Unlike general LLMs that hallucinate API parameters, Gorilla is trained on a curated APIBench dataset to produce syntactically correct, semantically appropriate API calls. It powers AI agents and copilots that need reliable tool use capabilities for orchestrating external services.
