DeepSeek open-sources DeepInfer inference framework

On the afternoon of 22 October 2026, a post titled "DeepSeek Open-Sources Its Production-Grade Inference Framework DeepInfer" appeared on Juejin, reporting that DeepSeek has released DeepInfer, the inference framework powering its online services. Citing the official announcement, the post claims that a single DeepInfer cluster processes 155 trillion tokens per day and that, at off-peak electricity rates, each GPU generates $38 in hourly revenue. The author says their first reaction to these figures was to open the source code and look around.

Earlier that same day, at 10:24, Juejin had already published "The Complete DeepInfer Guide: DeepSeek's Inference Framework — Principles and Deployment," a tutorial walking through DeepInfer's principles, architecture, and deployment practice. The tutorial argues that DeepInfer's value lies not in how many models it supports but in how deeply it is customized to make a single model run fast. No further detail on the release, the codebase, or the performance claims has been made available since these two posts, and DeepInfer's documentation or repository contents are not described in the available material.
