I use it with Qwen 3.5 running locally when my daily limits run out on my other subscriptions.
The harness is great. Local models are just slow enough that the subscription models are easier to use. For most of my tasks these days, the model's capability is sufficient; it is just not as snappy.
I briefly dabbled with Aider some months back but never got any real work done with it. Without installing each one of these new tools I'm having trouble grokking what is changing about them that moves the LLM-assisted software dev experience forward.
I just did a one hour vibe session today, ripping out a library dependency and replacing it with another and pushing the library to pypi. I should take my task list and let the local model replicate the work and see how it works out.
