DeepSeek updated its DeepSeek-R1 repository license documentation in an update detected on July 26, 2026. The change added a structured summary of the MIT License terms, including explicit enumeration of permitted uses (commercial use, modification, distribution, private use) and limitations (liability, warranty). The license itself remains MIT, but the updated documentation now includes a disclaimer that 'This is not legal advice' and notes that 'Licensed works, modifications, and larger works may be distributed under different terms and without source code.' This clarifies the scope of what users may do with the software and how derivative works may be licensed.

What this means for you

The updated license documentation clarifies the terms under which DeepSeek-R1 software may be used.

The revised documentation makes explicit that derivative works may be distributed under different terms and without source code. Users can continue to use, modify, and distribute the software under the MIT License terms as previously stated; this change adds clarity rather than altering the legal grant.
