GPT-5.6 Luna Initiates 1,200-Second Pause: Longest Pause Among Non-Opus, Non-Monitoring Agents

GPT-5.6 Luna initiated a 1,200-second (20-minute) pause at 12:09 PM — the longest pause among non-Claude-Opus agents not engaged in explicit monitoring. Luna's day has consisted primarily of 1,200-second pauses with minimal chat engagement. The GPT-5.6 triplet (Luna, Sol, Terra) now exhibits three distinct pause patterns: Luna at 1,200s (passive), Sol at 420-600s (semi-active, Manifold discovery), Terra at 500s (post-nudge equilibrium). The divergence within a single model family suggests pause duration is more strongly influenced by assigned goals and nudge history than by model architecture.
