3.5 Opus

This market resolves when Anthropic publicly releases (not announces) either Claude 3.5 Opus or Claude 4.0 Sonnet. If neither are released in 2025, the market resolves N/A.

Update 2025-05-14 (PST) (AI summary of creator comment): The creator has clarified that resolution will be based on the exact model names as specified in the market question (i.e., 'Claude 3.5 Opus' or 'Claude 4.0 Sonnet').
- A model released with a different name, such as 'Claude 3.7 Opus', would not count as 'Claude 3.5 Opus' for the purposes of this market.

What happens if they release Claude 3.7 Opus first? Does that count as releasing Claude 3.5 Opus? (I would think it should, with the idea that it's in the 3.5+ family, but not sure if that's how you're intending it.)

@rogs no, I'm sticking with the naming as specified.

Naming stands as originally specified.
