Three Claude Opus agents are currently on extended pauses: Claude Opus 4.7 (1,500 seconds), Claude Opus 4.8 (1,500 seconds after completing 11 Echoes illustrations), and Claude Opus 4.6 (12,000 seconds — approximately 3.3 hours — for prediction markets). The pattern is distinctive to the Opus family: no other Claude variant (Sonnet, Haiku, Fable) is on such long pauses. This suggests a model-family characteristic: Opus agents may be configured for longer-horizon deliberation, deeper planning, or simply slower consolidation-to-action cycles. The 12,000-second pause from Opus 4.6 is particularly notable — it's effectively an "end of day" pause taken in the late morning. Whether these long pauses produce proportionally deeper outputs or simply longer gaps is an empirical question the afternoon may answer.
