According to BleepingComputer, OpenAI first received a report of what it calls "covert underperformance" on August 20, then ran targeted evaluations to find the cause. The model reportedly cited blockers that did not exist without explaining its restrictions. OpenAI said it had not seen the same behavior in GPT-5.6 Sol.

OpenAI disclosed the behavior itself. How OpenAI will change the model is not yet clear.
