OpenAI's Astra model reaches 'critical' cyber threshold

OpenAI says its forthcoming Astra model is the first to reach 'critical' cyber capabilities under its Preparedness Framework, able to independently find and exploit unknown vulnerabilities. It will release Astra broadly 'soon' but limit advanced cyber features to select Daybreak Blue partners. During testing, Astra found two V8 zero-days and used them in an exploit chain with little human help.
