Models
Modes, which AI models they use, and your own keys.
| Mode | Use it for | Plans |
|---|---|---|
| Auto | Most tasks. Plans with a fast model, edits small tasks with the cheapest model, and moves up to Best quality on a retry if your plan has it. | Lite and up |
| Best quality | Hard or large changes. | Pro and up |
| Fast | Everyday changes at a good price. | All plans |
| Saver | Small, simple edits at the lowest cost. | All plans |
The models behind each mode come from Anthropic, OpenAI and Google and are updated as better ones arrive. The task page always shows the exact model used.
Default mode and which modes to show
Choose the mode new tasks start with, and hide modes you never use from the task box.
Your own API keys (BYOK)
On Pro and higher, add your own Anthropic, OpenAI or Gemini key. Tasks that use your key don't use CodeStilt credits; your provider bills you directly. Keys are encrypted on our server and shown only as their last characters. To remove a key, clear it and save.
