Latest update (11-11 05:03): vLLM upgrades its EPD encoder disaggregation with lower latency and higher throughput

Overview: vLLM announces on X on November 11, 2026, that its latest EPD encoder disaggregation improvements lower time to first token and raise throughput per GPU, counting encoder GPUs, and that the upgrade is integrated with vLLM Router, SMG, and llm-d. EPD separates the multimodal encoder into its own instance, and metadata-only requests let downstream instances skip media preprocessing and receive embeddings through connectors.

In a vLLM blog post dated November 10, 2026, vLLM reports a DeepSeek V4.1 Flash test on GB200 in which 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. The blog says initial support covers images, Model Runner V2, encoder TP=1, and no dynamic LoRA, and that DeepSeek V4.1 Flash metadata-only support is on main through #62802. No independent benchmark has been reported.
