According to @emollick, Nous Research’s Hermes Agent published a 79,456-word, 19‑chapter AI-written novel, The Second Son of the House of Bells, using an autonomous pipeline that mirrors Karpathy’s Autoresearch loop for fiction, including world-building, chapter drafting, adversarial editing, Claude Opus review loops, LaTeX typesetting, cover art, audiobook generation, and landing page setup; links to the book and code were provided (nousresearch.com/bells; github.com/NousResearch/autonovel) as reported by Ethan Mollick on X. According to Nous Research via the shared code and announcement, the modify‑evaluate‑keep or discard loop operationalizes agentic writing workflows that can reduce human-in-the-loop costs for long-form content production and enable scalable editorial QA with model-in-the-loop review. As reported by Ethan Mollick, early reader feedback highlights stylistic LLM artifacts (staccato dialogue, heavy metaphors, limited character differentiation), underscoring quality ceilings and offering clear benchmarks for model selection, adversarial editing rigor, and multi-model critique in commercial AI publishing workflows. According to the publicly shared repo, the stack demonstrates a reproducible template for AI-first publishing operations—combining narrative generation, typesetting automation, and multimodal assets—pointing to business opportunities in low-cost serialized fiction, audiobook pipelines, and white-label agent frameworks for publishers.
