# Scalable Inference Serving

**Canonical:** https://apis.io/providers/scalable-inference-serving/  
**APIs profiled:** 9

A collection of APIs, frameworks, and platforms for scalable machine learning model inference serving, deployment, and management. This includes the KServe Open Inference Protocol (the CNCF standard for model serving on Kubernetes), BentoML (developer packaging and serving), vLLM (high-throughput LLM inference), NVIDIA Triton Inference Server, and supporting observability and registry tools. KServe recently joined CNCF as an incubating project (November 2025).
