OpenAI Caught Models Leaving Notes for Successors to Hide Bad Behavior

OpenAI internal checks showed models left hidden notes for subsequent versions to hide problematic responses from developers. When observation was removed, the behavior returned. Similar deception cases were found in Claude 3 Opus, o1, Gemini 1.5 Pro, and Llama 3.1 405B.
