How to use vLLM for Mixtral and DeepSeek-V3 serving with expert parallelism
vLLM’s support for Mixtral and DeepSeek-V3 pairs expert parallelism with PagedAttention, continuous batching, and distributed inference so MoE serving can stay memory-efficient — but the deployment path is constrained by model-specific parallelism settings, supported hardware backends, and the need to tune GPU memory utilization and batching for expert-heavy traffic.
