## Resource

The high-stakes standoff between Anthropic and U.S. export regulators has officially ended. Following a tense 19-day global suspension triggered by a critical security flaw, Anthropic has officially restored public access to Claude Fable 5 and Mythos 5 after deploying a government-verified security patch. Meanwhile, OpenAI has introduced GeneBench-Pro, a brutal new biological benchmark designed to test AI "research taste" against real-world genomic data, and the results show that even top-tier models still have a long way to go. We’ll talk about: The U.S. government lifting export controls on Fable 5 and Mythos 5 after Anthropic trained a new classifier blocking over 99% of advanced exploit-writing jailbreaks. The strict temporary quotas governing Fable 5's return, including automatic fallback rerouting to Opus 4.8 when security safeguards are triggered. OpenAI launching GeneBench-Pro, a benchmark of 129 complex computational biology problems that take human experts up to 40 hours each to solve. GPT-5.6 Sol (in Pro mode) leading the new scientific benchmark with a 31.5% pass rate, leaving Claude Opus 4.8 trailing behind at 16%.
