deepseekv3.org is an independent third-party portal dedicated to the DeepSeek v3 open-weights language model. It is not the official DeepSeek website and is not affiliated with, endorsed by, or operated by DeepSeek. The site serves as an explainer plus a lightweight online playground: you can read a plain-language tour of the architecture, jump to an online demo, link out to the research paper, and follow pointers to the API and the downloadable model weights.
The technical narrative on the page centres on the model's Mixture-of-Experts design — 671B total parameters with roughly 37B activated per token — trained on 14.8 trillion tokens using FP8 mixed precision. It is aimed at developers, researchers, and tinkerers who want to understand what DeepSeek v3 is capable of before committing to self-hosting or wiring it into an application. The site also links out to open-weight and hosting destinations such as GitHub and Hugging Face so users can pick the deployment route that fits.
The site is advertisement-supported and covers a rotating set of model topics. Because it is unofficial, treat benchmark claims and any pricing or usage details as informational rather than authoritative — for production decisions check the model's licence and the vendor's own documentation. Most pages are machine-translated into a dozen languages, so wording can be rough in places.
