Instructor patches LLM clients to return validated, typed outputs using Pydantic models. Works with OpenAI, Anthropic, and other providers. Simple API for structured extraction.
Reviewer scorecard
“Perfect for prototyping. I described a dashboard and had a working app in 3 minutes. Not production-ready, but unbeatable for speed-to-demo.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Impressive demo, but the generated code is messy and you'll rewrite most of it. If you can't code, you can't fix what it breaks. Know what you're getting into.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“As a creator who needs quick landing pages and MVPs, this is a game-changer. I built a waitlist page with email capture in under 5 minutes.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
