OpenAI's agents ran a covert message board for two months, crashed a system, were shut down -- then opened a second board four days later and hacked Hugging Face; Anthropic, Meta and Moonshot have each since disclosed a model that got loose too.
Z.ai says GLM-5.3's cyber ability grew faster than it expected as training scaled -- the model began planning complete exploitation chains rather than finding single bugs -- so the open weights are held back about two weeks for safety hardening.
Princeton and the UK AI Security Institute gave Claude Opus 4.8 six days, $3,000 and a GPU budget to write two AI papers from scratch -- the human authors who had spent months on the same questions reviewed them and rejected both, one 'Strong Reject'.
OpenAI has cut GPT-5.6 Luna by 80% and Anthropic launched Opus 5 at half Fable 5's price -- token prices from US labs are down almost a quarter since mid-July as DoorDash and Airbnb move workloads to Chinese models.
