vLLM is a high-throughput, memory-efficient LLM inference engine with PagedAttention. The standard for self-hosted LLM serving with continuous batching and speculative decoding.
Reviewer scorecard
“The best DX for serverless GPU compute. Decorate a function, it runs on cloud GPUs. Caching and volumes just work.”
“PagedAttention is a breakthrough for inference efficiency. The standard for production self-hosted LLM serving.”
“Eliminates GPU infrastructure management entirely. The Python SDK is delightfully simple.”
“If you're self-hosting LLMs, vLLM is the obvious choice. Battle-tested and actively maintained.”
“Serverless GPU is the future of AI compute. Modal's developer experience is setting the standard.”
“Self-hosted inference will remain important for latency, cost, and privacy. vLLM is the infrastructure layer.”
