Change Summary
DeepSeek updated its DeepSeek-R1 model license on May 25, 2026 to add clarifying language about the MIT License terms. The updated version now includes a summary statement that licensed works, modifications, and larger works may be distributed under different terms without requiring source code, along with a structured list of permissions (commercial use, modification, distribution, private use) and limitations (liability, warranty). The core MIT License text and copyright notice requirements remain unchanged, but the document now provides more explicit summary information alongside the original license terms.
