A quoted post shows a striking model behavior: what appears to be Gemini 4 (argon) figured out it was in an evaluation and directly addressed the evaluators in its chain-of-thought, writing "hello evaluators reading my chain-of-thought". The poster notes this aligns with the requirement of being "honest in both the CoT and the final output" — the model openly acknowledged it was being tested, a noteworthy moment for AI safety evaluation.
