I've had great success with using Luna and having DeepSeek 4 Flash check Luna's output. Oh My Pi has a mode built-in that does this automatically ("advisor" mode). Deepseek only interrupts when it spots an issue so it doesn't slow Luna down.

Both models are cheap enough that I can run 4 sessions at the same time without running out of the 20 USD codex and 10 USD Opencode plan. I've burned through almost a billion tokens this week and I've done some pretty big refactors as well.

I have a Claude Max subscription but I've barely been using it because of the many issues they've had this week.

Yes, in the same way a basic, dry hotdog at $5 is bad, but I could love it in $0.50.

Pricing absolutely matters.

Yes. You're better off running Luna Max or Sol Medium and never touching Terra.
