Guidance is Microsoft Research's OSS library for guidance-augmented LLM generation — MIT license. Templating language for interleaving generation, control flow, regex, and tool use. Originated at Microsoft Research. Pick Guidance for template-driven LLM workflows where the DSL is the value prop.
Guidance's templating approach addresses LLM correctness via grammar-constrained generation. From a Trust Before Intelligence lens, this reduces prompt-injection + hallucination via structured generation. Trade-off: smaller community + slower production track record than Outlines/Instructor.
Token-level control adds overhead; net wins on retry reduction.
