repo is quite dead, for using new AI models

You can try to use this fork(not mine):

https://github.com/sheepy9/gipity.nvim

It points to gpt-5 there as default model, which doesn't work for me . but gpt-4.1 works..
The repo removed some commands (not sure why).

Let me know if I am not correct.

Not sure what it didn't work.

Start by comparing the current repository with the linked gipity.nvim fork and verify the reported gpt-5 and gpt-4.1 behavior. The issue provides no file or test entry point, so the expected model support and any command changes need clarification before implementation; done should include an agreed, reproducible result.
