- DeepSeek officially open-sourced DeepInfer, its in-house inference framework powering DeepSeek-V4.1-Flash at scale, under Apache 2.0 — aiming for high throughput, low latency, and lower compute/energy costs for the community.
- The repo acknowledges DeepInfer was initially built primarily on vLLM, with inspiration from SGLang and TensorRT-LLM.
- The vLLM team publicly thanked DeepSeek, noting they've been working on DeepSeek V4.1 Flash inference efficiency and will keep improving with ideas from DeepInfer.
