Reviewer scorecard
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“The deployment experience is unmatched. Git push → preview URL → merge → production. AI Gateway is a smart addition — route between AI providers without changing code.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“At small scale it's nearly free and incredible. At high scale, costs can surprise you. Know your usage patterns and set budget alerts. The product itself is excellent.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
“Vercel is building the cloud for the AI era — AI Gateway, Workflow DevKit, Edge Functions. They're not just a hosting platform, they're the application platform.”
