DeepSeek updated its DeepSeek-R1 model license on June 2, 2026 by adding clarifying language on GitHub describing the MIT License terms. The updated license now includes explicit statements that licensed works may be distributed under different terms without source code, and adds a summary of permissions (commercial use, modification, distribution, private use) and limitations (liability, warranty). The substantive MIT License text itself remains unchanged; the additions consist of explanatory metadata and GitHub-generated license summaries that clarify the scope of rights and restrictions already inherent in the MIT License.
The updated license clarifies that derivatives of the DeepSeek-R1 model may be distributed under different licensing terms without including source code. This reflects standard MIT License practice and does not materially expand or restrict rights previously available under the MIT License. Users may continue to use, modify, and distribute the model under the same permissive terms the license established.
The updated license language clarifies that downstream modifications of DeepSeek-R1 may be distributed under different licensing schemes without source code disclosure. This removes potential ambiguity about derivative licensing obligations and confirms the permissive nature of the MIT License, which may matter for commercial integrations of the model.
Updated language explicitly states that licensed works and modifications may be distributed under different terms and without source code, consistent with MIT License permissiveness.
