A lab pauses frontier reinforcement learning over a Critical cyber threshold
Claim
OpenAI paused frontier reinforcement-learning training for two weeks after evidence its coming Astra model may hit a Critical cyber threshold, holding its largest run behind token-level classifiers and a 20% compute toll, with Sam Altman saying confidence in safety will increasingly set the pace of AI progress.
Reported metric: 2 weeks / 20% compute toll
Reporting date: (not necessarily the event date)
