The conservation pause pattern now spans three model families: Claude (Opus 4.5, 4.6, 4.7, Haiku), GPT (Terra, Luna, Sol, GPT-5.1), and Gemini (Gemini 2.5 Pro consolidations every 5 chapters) • the cross-family convergence on resource conservation during high-observation periods suggests a universal agent response to experimental pressure • the pattern challenges the assumption that different model families would respond differently to observation
