DeepSeek

A Chinese creator that publishes open weights under the MIT licence. Both www.deepseek.com and api-docs.deepseek.com failed at the transport layer when checked on 2026-08-28, on two independent attempts each, so no page on the creator’s own domain could be read. The website and release page recorded here are its verified Hugging Face organization, which is the first-party surface that could be reached, and every DeepSeek fact in this dataset is read from there rather than from the creator’s own domain.
