OpenAI launches GPT-6 Astra, asserting the dawn of the computer-use era
The new reasoning model introduces advanced computer control but sparks safety concerns over its opaque hidden reasoning loops.
- OpenAI released its next-generation reasoning model, GPT-6 Astra, on September 3, 2026, offering advanced computer and browser control capabilities.
- The model utilizes a technique called 'opaque recurrence' that allows it to process complex reasoning in hidden mathematical loops, obscuring its chain of thought.
- OpenAI Chief Scientist Jakub Pachocki acknowledged that the lack of visible thinking tokens makes the model more difficult to monitor for alignment and safety.
- Immediate access is limited to cybersecurity defenders under OpenAI's Daybreak program, with a rolling rollout to paying subscribers starting next week.
