DeepSeek has fully open-sourced DeepInfer, an internally developed inference framework built to run its DeepSeek-V4.1-Flash model efficiently on Nvidia's SM100 Blackwell GPUs and Huawei hardware. The release, made on Tuesday, is framed by a senior company researcher as part of a wider contest between open-source and closed-source AI, described as a battle between "light and darkness". DeepInfer is tailored specifically to support DeepSeek-V4.1-Flash, and the company says it was developed in-house rather than adapted from outside work. By publishing the framework, DeepSeek is handing outside developers the same tooling it uses to serve its own model, which the company presents as a way to lower the cost of running AI.
