I think I found the item the grandparent commenter was presumably referring to - "Our position on open-weights models", posted by Amodei and dated July 27, 2026 - which includes: > some people have even accused Anthropic of wanting to ban open-weights models as a means of protecting our business. Anyone who has read my past writing should know that I don’t regard such bans as a useful measure, but let me state it clearly so that there is no doubt: *Anthropic has never advocated for a ban on open-weights models.* However, as you said, it also says "All sufficiently capable models, open and closed, should go through mandatory safety testing." https://www.anthropic.com/news/position-open-weights-models https://www.anthropic.com/news/position-open-weights-models
