DeepSeek modified its DeepSeek-R1 model LICENSE file on May 26, 2026 by removing three sentences of supplementary guidance text. The removed text included a statement about licensing flexibility ('Licensed works, modifications, and larger works may be distributed under different terms and without source code') and a disclaimer ('This is not legal advice'). The updated license now contains only the core MIT License text without the additional explanatory sentences, though the operative MIT License permissions and conditions remain unchanged.
The updated license file removes explanatory text but preserves the operative MIT License permissions and conditions. Users can continue to use, modify, distribute, and sublicense the DeepSeek-R1 model under the terms of the MIT License as previously stated. The removal of supplementary guidance language does not alter the legal rights or obligations established by the MIT License itself.
The updated license simplifies the license presentation by removing supplementary text, but the operative MIT License permissions and conditions remain substantively unchanged. Organizations using DeepSeek-R1 can continue to operate under the unchanged MIT License terms.
Explanatory sentences about licensing flexibility and legal disclaimer status were removed; core MIT License terms remain intact.
