{"slug":"best-model-serving-and-deployment-platform","title":"Best model serving and deployment platform","question":"What are the best model serving and deployment platform?","verdict":"As of 2026-07-15, ChatGPT, Claude, Gemini and Grok collectively rank vLLM #1 for model serving and deployment platform on ModelsAgree by aggregate score. The models' case: The de facto open-source standard for LLM inference in 2026 — PagedAttention and continuous batching deliver the best throughput-per-GPU, an OpenAI-compatible server out. The models' main caveat: It is an inference engine, not a full platform — you still bring Kubernetes, autoscaling, and observability yourself, and it does nothing for non-LLM. The strongest alternative is Modal — Best overall for typical practitioners: exceptionally fast Python-first deployment, broad GPU choice, scale-to-zero, strong autoscaling, custom. Not unanimous: ChatGPT picks Modal.
