SAN FRANCISCO: Anthropic announced Friday that it had received authorization from the US government to allow a small group of US cybersecurity firms to access its powerful AI model Mythos 5.
Access to Mythos 5 had been blocked by US authorities due to concerns about national security.
Anthropic, which has had a stormy relationship with the Trump administration for months, will continue discussions with the government to "expand access to Mythos 5 and make Fable 5 available again" to the general public, a company spokesperson said.
On June 12, the US government abruptly forced Anthropic to cut off access to its two cutting-edge AI models after discovering vulnerabilities in the safeguards put in place to prevent misuse of the tool.
The strong action against Anthropic has drawn accusations of government overreach.
In an earlier clash with the White House, Anthropic angered Trump's team by refusing to allow its technology to be used for mass surveillance and autonomous weapons, leading the Pentagon to cancel its contracts with the company.
Earlier Friday, Anthropic's main rival, OpenAI, launched its new model, GPT-5.6, with restricted access and validated on a client-by-client basis by the government.
