Reviewer scorecard
“Too expensive for what it offers. Plenty of open-source alternatives.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
“Fast, reliable, and the docs are actually good. Ship.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
