DeepSeek released DeepInfer on October 20, an open-source framework for running its V4.1-Flash AI model at scale. The release makes more of the model’s serving software available to developers and supports hardware from both Nvidia and Huawei.
DeepInfer targets V4.1-Flash
DeepSeek describes DeepInfer as a high-performance inference framework that powers its large-scale production services. Inference is the stage when a trained AI model generates answers for users. DeepSeek published the project on GitHub under the Apache 2.0 license.
The framework supports DeepSeek-V4.1-Flash and includes optimized kernels, asynchronous scheduling, deterministic sampling and structured outputs, according to its README. The project is publicly available through DeepSeek’s GitHub organization.
Nvidia and Huawei support included
DeepInfer supports Nvidia SM100 GPUs and Huawei Ascend 950 NPUs, according to the project documentation. This gives AI developers and cloud operators a serving framework designed for two different accelerator platforms.
The release is part of DeepSeek’s broader collection of open performance software. Its GitHub organization also lists DeepGEMM, a GPU library, and DeepGEMM-Ascend, a matrix-multiplication library for Huawei Ascend processors.
Developers gain another serving option
DeepInfer is most directly relevant to AI infrastructure teams, model hosts and researchers. It does not change the DeepSeek chatbot by itself, and the release does not mean that every computer can run V4.1-Flash efficiently.
The project documentation lists Linux, Python 3.12, CUDA 13 for Nvidia hardware and CANN 9.2 for Ascend hardware among its requirements. It also says a complete inference service needs additional components, including a key-value cache system and load balancing.
