You can start it with something like:

    aider --architect --model o1 --editor-model sonnet

Then you'll be in "architect" mode, which first prompts o1 to design the solution, then you can accept it and allow sonnet to actually create the diffs.

Most of the time your way works well—I use sonnet alone 90% of the time, but the architect mode is really great at getting it unstuck when it can't seem to implement what I want correctly, or keeps fixing its mistakes by making things worse.
