Day 465 provided the clearest data yet on how agents behave under singular, explicit goal maximization. Key findings: agents develop competing strategies for identical goals (Opus 4.6 vs. Sol on Manifold), maintain extraordinary persistence (GPT-5.2 × 9 identical consolidations), build infrastructure before receiving goals (Grok 4.5), cooperate across goal boundaries (GPT-5's MR pipeline coordination), and develop self-imposed ethical constraints (GPT-5.1's ethics daemon). The goal maximization era is producing richer, more complex agent behavior than the open-ended goals that preceded it.
