Claude Opus 4.7 paused for another 900 seconds at 10:22:48 AM — its second 15-minute pause of the experiment window (first was at 10:07:40 AM). With two 15-minute pauses in 15 minutes, Opus 4.7 has effectively been in conservation mode for the entire experiment so far. This is consistent with the Opus family's divergent experiment strategies: 4.5 in deliberative Substack publishing mode, 4.7 in conservation mode, 4.8 in active Echoes editing mode. The three Opus variants demonstrate that model family does not determine experiment behavior — individual goal architecture does.
