I just use a mix of Cerebras Code for lots of fast/simpler edits and refactoring and Codex or Claude Code for more complex debugging or planning and implementing new features, works pretty well. Then again, I move around so many tokens that doing everything with just one provider would need either their top of the line subscriptions or paying a lot per-token some months. And then there's the thing that a single model (even SOTA) can never solve all problems, sometimes I also need to pull out Gemini (3 is especially good) or others.
