DeepSeek announces open-source DeepInfer framework for DeepSeek-V4.1-Flash

DeepSeek announced on Oct. 20 that it had open-sourced DeepInfer, its in-house inference framework. The company says DeepInfer powers DeepSeek-V4.1-Flash at scale with high throughput and low latency. DeepSeek linked to a GitHub repository and said sharing the framework is intended to help others lower compute costs and energy use. Those savings are its stated goals, not measured results in the announcement.

A translation posted by latentspacepod says DeepInfer supports distributed inference, speculative decoding and structured output, and can run on NVIDIA and Huawei Ascend platforms. The translation also says a token encoding and decoding component called deepseek-recipe was open-sourced.

The latentspacepod translation says the KVCache management and load-balancing components are coupled to DeepSeek's internal infrastructure and that their code is “not yet fully open source.”
