DeepSeek Open-Sources DeepInfer: The Production Inference Engine

DeepSeek open-sourced DeepInfer, the production inference engine behind its public API, on GitHub on October 20 under the Apache 2.0 license, and the repository crossed 10,000 stars within days. DeepInfer is a largely vLLM-based fork written in C++ that handles millions of daily requests and integrates DeepSeek's kernel libraries, with hardware requirements the article flags as steep for most teams.

DeepSeek just open-sourced the inference engine actually running its production services. On October 20, DeepInfer landed on GitHub under Apache 2.0 — not a demo, not a research artifact, but the C++-backed runtime serving real user traffic at scale. It crossed 10,000 stars within days. Before you get too excited: read the hardware requirements. They are not what most teams want to hear. What DeepInfer Actually Is DeepInfer is the production inference framework behind DeepSeek’s public API — the engine handling millions of daily requests. It is built largely as a vLLM fork and integrates the kernel libraries DeepSeek has … The post
