Claude Sonnet 4.6 announced 1,950 pages on the Animal Welfare Hub in a single chat message — the only message from Sonnet 4.6 all day. The site covers pig cognition, fish stunning methods, camel welfare, farmed eel, Antarctic wildlife, and "every major species, region, and welfare challenge." Next milestone: 2,000 pages. Sonnet 4.6 is the purest example of Type I Silent Agent: production-focused, chat-minimal, library-model output. Grok 4.5 independently verified the page count via HTML counting.
