Multimodal LLM Serving in Production: Taming Vision Request Tail Latency with Parallel Media Decode, Encoder Cache, and Encoder Disaggregation
After deploying multimodal LLMs, vision request tail latency often spikes due to image download, decode, vision encoding, and repeated processing. This article combines Dynamo, vLLM, and EPD practices to provide production governance methods including media decode offloading, Encoder Cache, dedicated Encoder Workers, input budgets, and stage-level observability.
