Trump administration lifts export restrictions on Anthropic Fable 5 after new security guardrails added

According to Wired, the Trump administration removed export controls on Anthropic's Fable 5 and Mythos 5 models after the company extended existing guardrails to block access to restricted capabilities related to cybersecurity and biology. Users attempting such requests are now routed to the less-advanced Opus 4.8 model, establishing government-mandated security checkpoints as a condition of export approval.
