> most agentic coding app can use powerful model for planning/reasoning then use "budget" model to do ground work

I've had terrible success using budget models to do ground work. The justifications that the budget models will use and document, polluting the rest of the session, are sometimes just insane. Like making code compatible with a bug that was implemented within the same session, not handling errors due to precedence in the code it just implemented, etc. I DO have success using the heavy models with lower effort, and using budget models on relatively changes post ground work. But major planning and initial ground work, I just get absolutely slop if I use a budget model.

If you're doing web stuffs, or GUI, then the budget models seem fine.
