Reviewer scorecard
“The best DX for serverless GPU compute. Decorate a function, it runs on cloud GPUs. Caching and volumes just work.”
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“Eliminates GPU infrastructure management entirely. The Python SDK is delightfully simple.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Serverless GPU is the future of AI compute. Modal's developer experience is setting the standard.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
