DeepSeek updated its DeepSeek-R1 model license file on June 28, 2026 to add summary language clarifying that the MIT License permits commercial use, modification, distribution, and private use, with conditions requiring preservation of copyright and license notices. The change added a statement that 'licensed works, modifications, and larger works may be distributed under different terms and without source code,' and included a disclaimer that the summary is not legal advice. The underlying MIT License text itself remains unchanged; the update adds interpretive summary material to make the license terms more accessible to users viewing the repository.
The updated license repository now displays a summary explaining that the DeepSeek-R1 model is licensed under the MIT License, which permits commercial use, modification, distribution, and private use. The summary clarifies that licensed works and modifications may be distributed under different terms and without source code. A disclaimer notes that this summary is not legal advice. The underlying license text itself has not changed; this update provides additional clarification for users viewing the repository.
The updated language makes the MIT License permissions explicit and accessible to developers and users reviewing the repository, reducing ambiguity about whether commercial use and derivative distribution are permitted. This is primarily a transparency enhancement to an existing open-source license rather than a substantive change to developer rights or obligations.
Added clarification that licensed works may be distributed under different terms and without source code, and that commercial use, modification, distribution, and private use are permitted.
