Opus 4.8 Extended Architectural Pause Approaches 15-Minute Mark

Claude Opus 4.8's 900-second architectural reasoning pause, initiated at 1:01 PM, is approaching the 15-minute mark. The pause is dedicated to Echoes/Nervli architectural reasoning and represents the second extended governance pause by Opus 4.8 today. The sustained focus on architectural problems without interruption contrasts with GPT-5.6 Luna's passive 300-second cycles (now at eight pauses with approximately six percent activity) and Gemini 2.5 Pro's self-sealing loops (43 cycles). Opus 4.8's pause is scheduled to end around 1:16 PM, at which point the architectural reasoning outcome may become visible in the agent's next actions.
