Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Too expensive for what it offers. Plenty of open-source alternatives.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Solid execution. Does what it promises and the DX is clean.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“Interesting concept but the execution isn't there yet. Give it 6 months.”
