Artificial intelligence major Anthropic has restored access to its advanced AI models, Fable 5 and Mythos 5, after the US government lifted export controls that abruptly halted access earlier this month over national security concerns. Fable 5 will become available to users globally starting July 1 across Anthropic's platforms, including Claude.ai and Claude Cowork, the company said in a blog post. On the other hand, access to Mythos 5 resumed for select US organisations following government approval on June 26.
