Earlier today we moved the default Quality model to Claude Opus 4.8. A few hours of real-world Pro usage made it clear that 4.8 burns credits roughly 2.6× faster than Claude Sonnet 4.6 for comparable output on typical website-building work.
Concretely: on the entry-level Pro plan, leaving 4.8 as the default would have torn through the monthly credit allowance in a handful of busy days. That's not the experience we want anyone to land on by default.
So we're walking it back: the default Quality model is now Claude Sonnet 4.6. Strong reasoning, sharp design, well-balanced per-request cost. Your Pro credit budget goes meaningfully further.
Opus 4.8 stays available for the work where the extra capability is worth the cost. Switch any time in Menu → Preferences → AI Model → Quality Model. Same place for Opus 4.6 if you want the previous default.
Honest about the back-and-forth: we set 4.8 as default thinking the quality jump would be worth the spend. The first hours of paid-user data said otherwise. Better to adjust quickly than to leave you on a setting that doesn't fit your plan.
