DeepSeek updated the LICENSE file for its DeepSeek-R1 model on May 27, 2026, adding explanatory language about the MIT License. The update inserted a summary stating that 'licensed works, modifications, and larger works may be distributed under different terms and without source code,' along with a breakdown of permissions (commercial use, modification, distribution, private use) and conditions (license and copyright notice required). The practical effect is that the license file now includes GitHub's standard MIT License summary card, which clarifies permitted uses and conditions, without changing the underlying MIT License terms themselves.
