Greasy Fork

I saw in the comments that the script works even without a subscription. I tried it on Brave, but it didn't work.
Here's what I did:
1. The requirements say an old version of CAI Tools. You can find it on GitHub by downloading the code and unzipping the archive. You can install the unzipped extension in the extensions section by enabling developer mode.
2. I installed the script itself.
3. I launched any chat and clicked on the script itself, and got: "SUCCESS! Nyan model is set to default. Refresh the page!"
4. I refreshed the page.
5. The neural network model is the same (Pipsqueak).

What am I doing wrong?

So, I got it. The steps are the same, but with a slight difference.
Here's what I did:
1. The requirements say an old version of CAI Tools. You can find it on GitHub by downloading the code and unzipping the archive. You can install the unzipped extension in Extensions, enable developer mode, and then install it.
2. I installed the Tampermonkey script itself.
3. I launched any chat and clicked on the script itself, and I got: SUCCESS! Nyan model is set to default. Refresh the page!
4. Refresh the page.
5. The neural network model is the same (Pipsqueak). LOL! It doesn't work! That's what I thought and even considered deleting it :D.
6. I clicked *new chat*. And finally, I saw the coveted Nyan model.
