CNCF releases llm-d 1.0 for optimized LLM inference routing

By PulseAugur Editorial · [1 sources] ·

The Cloud Native Computing Foundation (CNCF) has announced the release of llm-d 1.0, an open-source project designed to optimize LLM inference routing. This new version supports model servers like vLLM and SGLang, and introduces a default routing strategy that prioritizes sending requests to endpoints already holding the prompt's prefix. This approach aims to significantly reduce GPU costs by maximizing prefix-cache hit rates, with reported throughput improvements of up to 2.9x compared to standard Kubernetes Service routing. The project, backed by major contributors including Red Hat, IBM, Google Cloud, CoreWeave, and NVIDIA, also includes features like KV cache offloading and multi-tenant quality of service. AI

IMPACT Optimizes LLM inference routing, potentially lowering GPU costs for services that heavily utilize prompt prefixes.
