DeepSeek V4 Pro 0813 (on OpenRouter)
DeepSeek’s new Pro model is API-only for now, with weights later appearing on Hugging Face at 1.7T parameters.
Willison linked to OpenRouter because DeepSeek had no obvious announcement page for the model. He initially could not confirm whether open weights would be released, then updated the note to say they were available on Hugging Face as an 893 GB download. He also found that its low, medium, and high reasoning levels produced notably different pelican images. Benchmark details were murky, apparently moving from a DeepSeek WeChat group to Reddit and then Hacker News. Simon Willison's note
