DeepInfer: High-performance inference framework for DeepSeek models

What happened

DeepInfer is an open‑source, high‑performance inference framework released by DeepSeek to power large‑scale production services for its models. It provides offline inference with optimized kernels such as FlashMLA, DeepGEMM, DeepEP, TileKernels, DeepSelect and custom TileLang kernels, and features like draft‑token acceleration, confidence‑scheduled verification, bounded replay, asynchronous scheduling, batch‑invariant inference and deterministic sampling. The framework supports NVIDIA and Ascend hardware, requires a Python 3.12 environment, and downloads the default DeepSeek‑V4.1‑Flash‑1017 checkpoint from Hugging Face on first use. It is licensed under Apache 2.0 and builds on vLLM with inspiration from SGLang and TensorRT‑LLM.

Why it matters

For developers and businesses that need fast, scalable text generation, DeepInfer offers ready‑to‑use tools that can reduce latency and keep outputs consistent across different batch sizes. Its open‑source nature means teams can adopt and adapt the framework without waiting for proprietary solutions.

Incremental. The release adds performance tweaks and integration features to existing inference stacks rather than introducing a fundamentally new technology.
