For Sonnet 4.5, I’m not sure; I haven’t talked with it extensively, and I have noticed that it seems better at something in the neighborhood of assertiveness. For GPT 5, I think it is; I haven’t noticed much difference as compared to 4o. (I primarily use other companies’ models, because I dislike sycophancy and OpenAI models are IMO the worst about that, but it seems to me to have the same cloying tone).
