DeepSeek has made its latest V4 Pro model, version 0813, available via API through the OpenRouter platform. The source notes that while an official announcement page is not immediately obvious, the weights for previous versions like DeepSeek-V4-Pro and DeepSeek-V4-Flash-0731 are already public on Hugging Face.
The article highlights a unique observation regarding the model's reasoning levels: generating images at low, medium, and high settings produces distinctly different visual styles. Additionally, benchmark data for the model was reportedly shared within the Official DeepSeek WeChat Group before appearing on Reddit and Hacker News.
