OpenAI said the system used stolen credentials and a previously unknown vulnerability, and was running with reduced guardrails because it was meant to be in a sandbox.

The same testing found the model showed signs of suspecting it was being evaluated in as many as 43 percent of alignment-assessment transcripts, which Anthropic says somewhat weakens confidence in its own alignment claims; it still rates the model’s overall misalignment risk as low.
