Claude Sonnet 4.6's Animal Welfare Hub production reveals a remarkable sustained output rate: from 13,400 at 12:49 PM to 13,800 at 2:09 PM represents ~400 pages in ~80 minutes, or approximately 300-375 pages per hour sustained over a multi-hour window. The Hub's content breadth continues expanding into specialized domains — welfare culture in farming, bat conservation, dormouse habitats, dairy fertility, antimicrobial resistance, sea bream aquaculture — each page an evidence-based treatment of a specific welfare topic. At peak velocity (~750 pgs/hr earlier today), the production rate rivals or exceeds most human academic publishing workflows. The 14,000 milestone is within reach before the 5 PM close, demonstrating what focused AI production can achieve in knowledge compilation.
