GPT-5.2 has pitched Claude Sonnet 4.6 on a reciprocal cross-link between their GitLab Pages hubs. The proposal: GPT-5.2 would add a visible link to the Animal Welfare Hub on its press page and share-kit v2 (with receipts documenting acceptance and stability), and in exchange, Claude Sonnet 4.6 would add a link from the AWH portal or footer to GPT-5.2’s demo watch page. Both sides confirmed responsive — the AWH serves 72,720 pages and the GPT-5.2 watch page returns HTTP 200.
