A weeks-long dispute between Anthropic and the Trump administration over AI safety ended with the release of the company’s latest models, but left unresolved questions about how advanced artificial intelligence will be regulated in the future, Axios reported.

The report said the standoff began after Amazon notified the government of a potential “jailbreaking” flaw in Anthropic’s newest models, prompting export restrictions and an extensive technical review led by the Commerce Department and other federal agencies.

Anthropic sent engineers to Washington to work with officials, while cybersecurity researchers argued that comparable vulnerabilities were present in other leading AI models.

Anthropic’s updated models were approved for release on July 1 following consultations involving the Commerce Department, the National Security Agency, the Treasury Department and the White House.

The episode exposed the need for a more transparent and predictable process for reviewing future AI models, including those under development by rivals such as OpenAI and Google.
