AI models
Wyber uses Claude by Anthropic to power code generation, agent planning, and workflow logic. Higher-tier plans unlock access to more powerful model versions.
Available models
| Model | Speed | Quality | Available on |
|---|---|---|---|
| Fast (Haiku) | Fastest | Good | All plans |
| Standard (Sonnet) | Fast | Great | All plans |
| Premium (Opus) | Slower | Best | Builder & Team |
| Fable | Slowest | Most powerful | Team (BYOK) |
How model choice affects output
For most app builds, Standard (Sonnet) is the sweet spot — fast generation, excellent output quality, and 1 credit per message. Use Fast (Haiku) for quick edits and small changes where speed matters more than detail. Premium (Opus) is best for complex multi-screen apps with intricate logic, detailed UI, or large data models — it produces noticeably more complete output at the cost of longer generation time.
Using your own Anthropic key (BYOK)
You can bring your own Anthropic API key to use any Claude model — including Fable — at your own rate limits. Your key is stored encrypted and never exposed in generated code. See Bring your own keys for setup steps.
