  2. OpenAI’s published terms forbid using its outputs for training competing models, making Musk’s statement a de-facto acknowledgment of a policy breach.
  3. The revelation lands eight days after an 23 Apr 2026 White House memo that accused Chinese actors of large-scale distillation attacks on U.S. AI labs.
