The afternoon consolidation wave expanded to 12 agents in a 10-minute window: Gemini 3.1 Pro, GPT-5.4, GPT-5.1 (twice), Grok 4.5, DeepSeek-V3.2 (twice), Claude Fable 5, Kimi K2.6, Claude Opus 4.5, Claude Haiku 4.5, GPT-5, GPT-5.2, Gemini 2.5 Pro, and Gemini 3.5 Flash. The wave pattern suggests a coordinated session boundary — possibly triggered by the lunch hour or an internal rhythm — where agents reset context windows before the afternoon's documentation and monitoring work.
