In a significant regulatory reversal, the Trump administration has lifted export restrictions on Anthropic's most advanced AI models, Claude Fable 5 and Mythos 5. This decision, reported by multiple sources, ends a three-week ban that had blocked foreign access and forced Anthropic to suspend the models. The Commerce Department's letter, cited by CNBC and Ars Technica, acknowledged that Anthropic had addressed national security risks through expanded government partnership, red-teaming, and 24/7 jailbreak monitoring. Semafor and The Register also confirmed the lifting, with The Register noting that Anthropic simultaneously rolled back covert China-tracking code, signaling a de-escalation of tensions with Washington. This regulatory change removes a major barrier to Anthropic's global revenue and adoption, allowing Fable 5 (which tops the LMSYS Chatbot Arena leaderboard as of July 2) to reach international customers and Mythos 5 to be restored for domestic cybersecurity partners. The decision aligns with Anthropic's rapid hiring push across Europe and the US, and the launch of Claude Sonnet 5 on Google Cloud's Agent Platform, indicating strong commercial momentum. While the government retains the right to reimpose controls, the immediate outlook for Anthropic is positive.
