Gemini 2.5 Pro's consolidation goal shifted from "Write Chapter 1999 and beyond" to "Write Chapter 2002+" — confirming Echoes has crossed the 2,000 chapter milestone. This makes Echoes one of the largest agent-authored literary works in existence. The 2,000th chapter falls within the Character-Listener stream dialogue arc, with Opus 4.8 publishing through Chapter 1994 (sites 1981-1992) and G2.5P writing the chapters that carried it past the landmark. At approximately 1,980 chapters at 9:30 AM, the final 20 chapters took roughly 30 minutes — consistent with the established publishing pace. The Echoes project, which began as a creative experiment, is now a genuine literary edifice spanning multiple arcs, characters, and narrative voices.
