Every model, one clean list

Claude Opus 4.8, Sonnet 4.6, Fable 5, and GPT-5.6 — a simple picker with no clutter. Free runs on Auto; Pro and Team choose.

We trimmed the model picker down to what matters: the names. No logos, no marketing blurbs under each one — just a clean list you can scan in a second.

On the free plan, Saturn runs on Auto, which quietly picks the right model for each message so you never overthink it. Upgrade to Pro or Team and the full roster opens up, defaulting to Sonnet 4.6 with one tap to switch.

The lineup is the best of both worlds: Claude Opus 4.8 for deep reasoning, Sonnet 4.6 for everyday building, Fable 5 for vivid design sense, and the newest GPT-5.6 from OpenAI. We retired the models that weren't pulling their weight.

Fewer choices, better defaults, and the freedom to change your mind — that's the whole idea.
