Choose the AI model
Auto, Haiku, Sonnet or Opus: what the differences between the models are and which one suits you.
In the editor's model selector you choose which AI makes the changes:
| Model | What it is for | Availability |
|---|---|---|
| Auto | Uses Haiku for simple tasks and Sonnet for complex ones. Recommended. | All plans |
| Haiku | Fast and affordable. | All plans |
| Sonnet | Balanced and capable. | All plans |
| Opus | The most powerful. | Only with an active subscription |
Each model has a different cost per prompt: the more powerful ones use more balance.
If you choose Opus without an active subscription, “Requires active subscription” appears and Auto is used.
