Could be an option

I use AI as a sort of junior developer, I know the problem domain but a bit to lazy to write all the code. I develop on a remote Linux VM with tmux, nvim and opencode. Have the ai tmux session and my development session on a different project. Make sure to have a clean git tree and then I detach from one session to the ai session and check the progress.

The ai makes mistakes so a cautious review of all the code is needed.

I mostly use Claude and I can NOT recommend any kimi k2 model. If you need something okish and cheap use open router gpt-oss 120.

AI is a power tool if you don’t know what are you doing you get burned.

I can confirm that.
