OpenAI's ChatGPT-5.6 gets the same banhammer treatment as Anthropic’s Mythos from the federal government — source says that Washington cautioned OpenAI against releasing the model without receiving approval

The U.S. government wants dibs on U.S. AI labs' most powerful models, asking for access 30 days before they go public. OpenAI is voluntarily complying with the President's executive order but wants 'to achieve a more sustainable approach for future releases.'
The U.S. government is actively asserting regulatory control over advanced AI models as their capabilities rapidly increase, viewing them as critical national infrastructure.
This intervention signals a tightening grip on frontier AI development, potentially setting a precedent for future global AI governance and altering release strategies for powerful models.
AI developers will likely face increased scrutiny and mandatory pre-release access requirements from the U.S. government, impacting innovation speed and competitive dynamics.

The immediate impact is a delay or modification of OpenAI's ChatGPT-5.6 and Anthropic's Mythos public releases.
This could lead to a 'safe harbor' approach for some AI development, with a two-tiered system for models deemed sensitive or powerful.
It might accelerate the development of independent, sovereign AI capabilities in other nations to avoid reliance on U.S.-controlled models.
