ZDNET’s key takeaways

  • OpenAI released its previously paused Astra model.
  • Researchers are worried the powerful new model could endanger security at scale.
  • OpenAI said Astra triggered new internal safety guardrails.

OpenAI’s latest model, named Astra, is finally loose — sort of.

The company halted development on Astra, also known as GPT-6, after July’s now-infamous Hugging Face incident — in which an OpenAI agent hacked the developer site, and several others — as it reevaluated internal security standards. As of today, the model is live for a select group.

OpenAI emphasized that Astra sets a new standard for computer use, taking “about 47% less time per task than GPT-5.6 Sol, scoring 72.6% at roughly 40 minutes per task.” In addition to its engineering and browser use capabilities, the company mentioned the model’s cybersecurity prowess and ability to advance science, citing new discoveries in math and reasoning scores for biology.
