But I do use claude code tui because I have a sub: it is a good model and I like its aesthetics. If I could use the sub in my own harness I would. It's also a foil to GPT's models that overengineer everything.
I have a Codex subscription that I use in my own harness, dreamcoder.ai, which has a tiling window manager and all the other mod cons you'd expect a frontier harness to have.
In addition to that, I run Qwen 3.8 27B NVFP4 with ninfer on my 5090. It's a great model for local development. I also use that in dreamcoder.
