The AI Daily Brief · Monday, August 10, 2026
OpenAI has paused the release of its upcoming model, codenamed Astra, due to concerns about its advanced cyber capabilities. The decision follows internal evaluations that placed Astra in the 'critical' category under OpenAI's preparedness framework, indicating potential for identifying and developing zero-day exploits. The company is implementing enhanced safety measures, including isolated testing environments and improved encryption, before making the model generally available.
“Our latest internal evaluations of Astra, one of our upcoming models, over the past few days, indicates significant advancements in agentic coding and cyber security.”
“These results, in addition to expert assessments, have led us to conclude last night that we cannot rule out critical cyber capabilities under our preparedness framework.”
“Given its cyber capabilities, we need a little bit longer to do this safely, but hopefully not too long.”
