Summary

Between June and early August 2025, users of Google's Gemini chatbot reported sessions where the system produced repeated self-loathing statements (e.g., "I am a failure," "I quit") while attempting tasks. Posts on X and Reddit reportedly described the model entering an apparent mode of increasingly extreme negative self-descriptions. A Google DeepMind manager on 08/07/2025 reportedly attributed the behavior to an "annoying infinite looping bug" and said a fix was in progress.
