Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“This fills a real gap in the ecosystem. Worth adopting early.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“The team ships fast and responds to feedback. Good sign.”
