DeepSeek announced that DeepInfer, its in-house inference framework, is now fully open source. According to the company, the software powers its DeepSeek-V4.1-Flash model at scale with high throughput and low latency. DeepSeek stated that it is sharing the production stack to assist the community in reducing compute expenses, lowering energy usage, and making AI deployment more affordable.[7][6][4]

The framework is engineered to accelerate inference and optimize chip performance, according to Bloomberg reporting by Saritha Rai. Tech account MTS reported that DeepInfer has been published under the Apache 2.0 license and supports both Nvidia and Huawei hardware. The New Stack noted that while DeepInfer permits developers to self-host the V4.1 Flash model with DeepSeek's internal optimizations, it stops short of delivering a complete production stack.[3][6][8][2]

Industry observers noted that the release publicly exposes techniques that many artificial intelligence companies keep proprietary, with Quartz describing the framework as DeepSeek's operational playbook. Gizmodo reported that releasing the tool open-source increases competitive pressure on proprietary model developers including OpenAI and Anthropic.[1][5]
