OpenAI paused RL training for two weeks and added a monitoring compute cost over Astra's cyber tier reading

OpenAI has reportedly paused RL training for two weeks and incurred additional monitoring compute costs due to Astra's cybersecurity tier assessment. This decision stems from OpenAI's internal preparedness framework, which classifies Astra as the first model that cannot be ruled out from meeting the "Critical" cybersecurity threshold. This assessment has sparked discussion regarding whether it reflects genuine evaluation uncertainty or strategic pre-positioning for a potential "Critical" rating at launch, and if external validation of this reading has been publicly detailed.
