Reviewer scorecard
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
