Reviewer scorecard
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“Model Garden gives you access to every major model with enterprise security. Feature Store and pipelines are production-grade.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“GCP complexity tax is real. Unless you're already on Google Cloud, the onboarding friction isn't worth it.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
“Google's AI infrastructure advantage (TPUs, models, data) makes Vertex the dark horse enterprise AI platform.”
