NVIDIA says ModelExpress moves DeepSeek-V4 Pro startup below 2 minutes
NVIDIAAI · x · 2026-07-25
NVIDIA says its ModelExpress (MX) service inside Dynamo can cut DeepSeek-V4 Pro startup time from 8 minutes to under 2 minutes.
- MX moves weights over GPU-to-GPU RDMA and reuses kernel caches.
- It avoids centralized broadcasts by letting inference workers fetch updated weights directly from other GPUs via NIXL.
- NVIDIA says the same design speeds up both inference and RL post-training by keeping weight transfer off the critical path.
