Version History

• June 25, 2026 v1 low
  DeepSeek's GitHub repository page for the DeepSeek-R1 model experienced a technical display error on June 25, 2026, causing the LICENSE file view to show an error message rather than the actual license text. The underlying MIT License file itself remains intact and unchanged, containing the standard MIT terms authorizing commercial use, modification, distribution, and private use. The operational impact is that users attempting to view the license terms through the GitHub web interface encounter an error rather than readable license text, though the raw license file and its actual terms remain accessible through alternative GitHub viewing methods.

• June 21, 2026 v1 low

• June 16, 2026 v1 low
  The provided diff context shows nearly identical MIT License text before and after the detected change on June 16, 2026. The only observable difference appears to be a metadata change in the GitHub repository statistics (Pull requests count changed from 23 to 24), not an alteration to the actual license terms themselves. The MIT License language permitting use, modification, and distribution of the DeepSeek-R1 software remains unchanged.

• June 11, 2026 v1 low
  DeepSeek updated its MIT License file on June 11, 2026 by removing supplementary documentation and clarifications that previously appeared alongside the standard MIT license text. The change removes three sentences that described permitted uses (commercial use, modification, distribution, private use), limitations (liability, warranty), and conditions (license and copyright notice), along with a disclaimer stating 'This is not legal advice.' The core MIT License text granting rights to use, modify, and distribute the software remains unchanged. The practical effect is that users now encounter only the standard MIT License language without the prior explanatory framework.

• May 27, 2026 v1 low
  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.

• May 16, 2026 v1 low
  The detected change shows only a minor, non-substantive difference in the GitHub repository metadata: the pull request count increased from 14 to 15 in the file view interface. The core MIT License text itself remains identical across both versions. This is a repository activity update, not a change to the licensing terms or legal permissions that govern the DeepSeek-R1 software.
