Chaofa Yuan (袁朝发)
Chaofa Yuan is an LLM (large language model) engineer and technical blogger who has long written under the pen name “chaofa用代码打点酱油” (roughly “chaofa does odd jobs with code”) and runs his personal blog at yuanchaofa.com. He describes himself as “业余野生视频博主，专业大模型算法工程师” (an amateur video creator by night, a professional LLM algorithm engineer by trade). Per a monthly recap on his blog dated June 2026, articles and videos from then on are signed with his real name, 袁朝发.
Background and notable work
The following is based on his blog:
- Blog topics include agent system design (such as Harness Engineering and a series on prompt caching in agent systems), hand-writing LLM components from scratch (self-attention, RoPE, DPO) and paper readings (such as DeepSeek’s MLA and R1, and a technical breakdown of Kimi K2.5).
- Beyond writing, he publishes technical videos on Bilibili and produces the podcast 《逃逸速度》 (Escape Velocity).
- The blog offers RSS subscription and pages such as LLMs-Zero-to-Hero.
No reliable public account of his employer or education is available, so none is given.
Mentioned in the show
Yuan does not appear in the episodes quoted on this page; the following is a host’s relay. In the RSS, independent blogs and open content chapter of Weekly #005 (Chinese transcript), Xiangyang Qiaomu says: “我看那个 X 上有谁的一个袁朝发是一个这个也是做这个大模型的，然后他说他自己一直在运营自己的独立博客，然后但是他公众号做一个对比，就是独立博客同样一篇文章远远不如公众号阅读量大和多，他就会觉得那我辛苦维护这个独立博客，那我是不是还不如发公众号？” (“I saw on X, someone — Chaofa Yuan, he also works on large models — he said he has always run his own independent blog, but comparing with his WeChat official account, the same article gets far fewer reads on the blog, so he wonders whether maintaining the blog is worth it versus just posting on WeChat”) (see that line).
The relay appears in the hosts’ discussion of Chinese content lacking RSS, closed official accounts, and the value of independent blogs in the agent era: Yuan’s observation raises the question of whether to keep maintaining a blog whose readership trails WeChat official accounts. His original post on X is the authoritative source.
