DeepSeek updated the LICENSE file for DeepSeek-R1 on June 21, 2026 by adding clarifications to the MIT License display. The updated document now includes a statement that licensed works, modifications, and larger works may be distributed under different terms and without source code, alongside a structured summary of permissions (commercial use, modification, distribution, private use), limitations (liability, warranty), and conditions (license and copyright notice). The change does not alter the underlying MIT License text itself, which remains standard open-source boilerplate, but adds explanatory metadata and contextual language around how the license operates.

What this means for you

The updated LICENSE file now includes explanatory language clarifying that works distributed under the license may use different terms and may be distributed without source code, though the core MIT License permissions remain unchanged. This addition does not alter what the MIT License permits; it provides additional context on how derivative works may be licensed. No specific action is required by users; the core license terms and permissions remain the same.
