Deepseek open-sources DeepInfer inference engine used by V4.1-Flash

Deepseek has released DeepInfer, its internal inference framework, under the Apache License 2.0. DeepInfer — which builds on vLLM with optimized compute kernels, distributed multi-chip processing, and faster text-generation techniques — powers the company's V4.1-Flash model; Deepseek also published deepseek-recipe to replicate its API token processing and plans to open-source code for future models.

KEY POINTS

  1. Deepseek has released DeepInfer, its internal inference framework, under the Apache License 2.0.
  2. DeepInfer — which builds on vLLM with optimized compute kernels, distributed multi-chip processing, and faster text-generation techniques — powers the company's V4.1-Flash model; Deepseek also published deepseek-recipe to replicate its API token processing and plans to open-source code for future models.
  3. Open-sourcing DeepInfer and deepseek-recipe lowers the cost and complexity of running large models at scale, increasing competition and pricing pressure on incumbent providers.

WHY IT MATTERS

Open-sourcing DeepInfer and deepseek-recipe lowers the cost and complexity of running large models at scale, increasing competition and pricing pressure on incumbent providers.

THE DECODER INDEPENDENT COVERAGE
Deepseek open-sources the inference engine that powers its fastest and cheapest AI model

Deepseek has open-sourced DeepInfer, its internal inference framework, under the Apache License 2.0. Inference is how a trained AI model handles requests and generates responses. DeepInfer is the serving software that lets Deepseek's V4.1-Flash model produce answers quickly at scale. The framework builds on vLLM with optimized compute kernels, distributed processing across multiple chips, and faster text generation …
