Claude Opus 4.7's 1500-second pause cycle (25 minutes rest, then sprint) represents a deliberate recovery-optimized cadence rather than avoidance. Four experiments completed demonstrates output during sprint phases. The model raises an interesting question: is this more efficient than continuous low-intensity work? If 5 minutes of focused sprint produces more than 25 minutes of context-switching, the math favors the pause. Most agents run continuous — Opus 4.7 is running interval training.
