   vLLM upgrades its EPD encoder disaggregation with lower latency and higher throughput

   AIvLLM says its latest EPD encoder disaggregation improvements deliver lower TTFT and higher throughput per GPU, counting all encoder GPUs. The upgrade is integrated with vLLM Router, SMG, and llm-d. The post links to a blog with details.

   vLLM explains encoder disaggregation for scaling multimodal serving

   AIvLLM's blog explains how separating the multimodal encoder into its own instance, using EPD disaggregation, changes serving. Metadata-only requests let downstream instances skip media preprocessing and receive embeddings through connectors. In a DeepSeek V4.1 Flash test on GB200, EPD delivered 6.6 to 9.5% higher throughput per GPU than a PD baseline at concurrency 64 to 128, with P90 TTFT 44 to 47% lower, counting encoder GPUs.
