White House opposes Anthropic's plan to expand Mythos AI model access to an additional 70 firms, raising total to 120 entities.
Officials cite security risks, noting Mythos can locate software vulnerabilities and enable large‑scale cyber attacks.
Concerns also include Anthropic's limited computing capacity potentially restricting government usage of the model.
Anthropic is seeking funding at a $900 billion valuation to double its current worth and acquire needed compute power.
