Anthropic and the Trump administration reached a deal on Friday to bring one of the company’s most powerful artificial intelligence models back online, after days of tense negotiations.
In a letter sent to Anthropic, the Commerce Department gave the San Francisco company permission to restore some clients’ access to its Mythos 5 model, which the government restricted two weeks ago because of national security concerns.
Talks were still underway to restore access to another powerful Anthropic model, Fable 5, and to provide Mythos to more organizations, said a person familiar with the talks, who spoke on the condition of anonymity because the person was not allowed to discuss them publicly.
“Anthropic has worked with the U.S. government to address risks associated with the covered models,” said the letter, which Commerce Secretary Howard Lutnick sent to Anthropic on Friday. “These efforts have yielded significant progress.”
Mr. Lutnick added that Anthropic had committed to working with the U.S. government on protocols for future releases of A.I. models.
A spokesperson for Anthropic said the company was working to restore access to the clients approved by the administration and was “pleased to see this progress and continue to work with the government.”
