Auto routing: Saturn picks the right model for every message
New projects default to Auto — Haiku for quick questions, Sonnet or Opus when the build needs depth.
We shipped Auto routing so you don't have to guess which model to pick. Saturn classifies each message — new app, feature, tweak, fix, or question — and routes it to the model that fits.
On Free, big builds use Saturn Smart (Sonnet) to keep quality high without burning credits on overkill. Pro and Team get Saturn Advanced (Opus) for scaffolds and substantial features.
You can still override Auto anytime from the model picker. Your choice is remembered per project.
