A red heart in the prompt flipped Claude Opus 4.7 and GPT-5.4 to recursive code, Google DeepMind researchers report
A Google DeepMind preprint reports that simple images such as a red heart can steer Claude Opus 4.7, GPT-5.4 and Gemini 3.1 Pro toward different coding and writing choices, often without the models' reasoning admitting i…
