DeepSeek Made Its Small Model Beat Its Big One. The API Name Didn't Change.

DeepSeek shipped V4-Flash-0731 on July 31 with the same architecture and size as the April preview and only a new post-training pass. DeepSWE went from 7.3 to 54.4 and the small model now beats DeepSeek's own larger V4-Pro on every agent benchmark published. The weights got a dated Hugging Face repo. The API kept the same floating name.
