Overview
- DeepSeek on Thursday released DeepSeek‑V4‑Pro‑0813 across its API, app and web and published the model weights under an MIT license on Hugging Face.
- The company also published Harness v0.1 as an open‑source developer preview, a MIT‑licensed agent runtime designed to turn V4 models into autonomous coding agents and backed by a newly formed ‘Harness’ team.
- DeepSeek listed API prices of about $0.435 per 1 million input tokens and $0.87 per 1 million output tokens and said it will raise prices for V4 Pro and V4 Flash and introduce peak/off‑peak rates to manage heavy demand.
- Independent benchmarks show mixed results: V4‑Pro‑0813 trails some frontier models on broad reasoning indices but performs strongly in niche tests such as cybersecurity, while DeepSeek’s comparisons emphasize only small gaps to Claude at a tiny fraction of the price.
- Rapid token consumption has strained compute capacity, prompting aggressive hiring, plans for onshore data centres and chip design, and a large fundraising push that seeks capital to finance scaled infrastructure and wider commercial adoption amid data‑sovereignty limits.
