    I have the same problem, no matter what Sonnet version I select, it reports itself as 3.5. If you question this, it says that versions 4 and 4.5 don't exist as of October 2024 :)
    Also, if I select GPT-5 as model, every request fails with a 400 error.

    I tested this on Linux.

    I wouldn't trust how the model self-reports, we haven't done anything in our prompts to ensure that it says the right thing here!

    Going to close this issue in favor of tracking this here: #108
