Reviewer scorecard
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Python script to interactive web app with zero frontend code. The caching and state management work well.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“For data scientists who don't want to learn React, Streamlit is the best option. Quick prototyping and dashboards.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
“The UI options are limited compared to real frontend frameworks. Fine for internal tools, not for customer-facing apps.”
