What was your prompt? It's important to remember that Claude and GPT are prone to bullsh¡t. When asked to compare apples to oranges, they will happily and confidently make the comparison even if it's a category error. Leitgeb's footnote might be of use: "This motivation for Ramsifying classical semantics is orthogonal to instrumentalist or functionalist motivations: the point of Ramsey semantics is neither to show that talk of interpretation is merely instrumental nor to convey insights into the ‘nature’ of truth, but to deal with semantic indeterminacy. In contrast, e.g., Wright’s [85] paper on Ramsification and monism-vs.-pluralism-about-truth does not apply Ramsification for the sake of doing semantics and in fact presupposes semantic determinacy (see [85], p. 272)." where [85] is: Wright, C. (2010). Truth, Ramsification, and the pluralist’s revenge.
