Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“The 'copy into your codebase' approach is genius. Full ownership, full customization, no version dependency hell.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Solved the component library problem by not being a library. The most practical approach to UI components.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“Beautiful defaults that look professional immediately. The theming system makes brand customization straightforward.”
