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.
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.
Earlier on Friday, OpenAI, Anthropic’s main rival, unveiled an A.I. technology called GPT-5.6 Sol, saying it matched the performance of Mythos on standard benchmark tests used by A.I. companies. OpenAI said it would initially share the technology with only a small number of companies approved by the administration.
