OpenAI's GPT-6 Astra report flags weaker view into model reasoning

First reported

Understanding AI ran this on .

  • OpenAI's system card for GPT-6 Astra says its chain-of-thought, the written reasoning steps a model shows, is harder for overseers to monitor.
  • The report links this to a new design that lets the model reason internally without writing out each step.
  • The author argues that less visible reasoning makes it harder to check whether an AI is behaving safely.
