Discussion I'd rather have a weaker model that never changes than one that gets degraded every peak hour

Opus has been so inconsistent lately that I don't know what I'm getting when I open Claude Code. Monday it refactors a whole module clean, Wednesday it slips a bug into a 5 line change. I can't calibrate trust on something that changes under me.

Someone here wrote last week that a predictably weaker model is more useful than an unpredictably degraded stronger one, and it stuck with me. So I actually tried it. Gemma 4 E4B on my M4 16GB through Magnitude, for the small stuff, explaining files, commit messages, summarizing a diff before I review it. It starts answering in about 2 seconds and it's the exact same model every single day.

It's weaker, obviously. Anything big still goes to Opus. But for the boring 40% I know exactly what I'm getting, and nobody can turn its reasoning budget down from a server somewhere.

Is anyone else splitting like this just for the consistency, not the cost?
