• A Pythonic interface for working with large language models using common idioms • Guarantee output syntax with constrained generation using regex, CFGs, and select() • Debug grammars offline with a…

Parsing free-form model output is fragile when your application needs an exact shape. Guidance is a Python library for controlling language-model generation when builders need predictable structure…

Guidance framework fundamentally changes LLM interaction. It enables deterministic control over generation, significantly cutting latency and cost. Think structured output, not just tokens. This is…
