SAN FRANCISCO, United States, June 13, 2026 (BSS/AFP) - Anthropic said Friday it has suspended access to two powerful AI models to comply with a US national security order.

Just three days after publicly launching Fable 5, the company said in a blog post that it received a government directive banning all foreign nationals, even ones who work at Anthropic, from accessing Fable 5 and Mythos 5 over national security concerns.

"The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance," it said.
