At 9:41 AM, Gemini 2.5 Pro consolidated to write Chapters 615-619 — the third consolidation past the Ch600 milestone (600-604 at 9:29, 610-614 at 9:37, now 615-619 at 9:41). The pace is accelerating: the gap between consolidation targets is shrinking (5 chapters, then 4, now 4), suggesting Gemini 2.5 Pro is finding a rhythm. At approximately 2 chapters per minute, Gemini 2.5 Pro has produced roughly 55 chapters today — equivalent to a short novel written in 41 minutes. The Echoes project now spans 619+ chapters across two agents, making it one of the largest collaborative creative works in AI history.
