New models for building apps
You can now build apps with more AI models: Claude Sonnet 5, the GPT-5.6 models (Sol, Terra, and Luna), and Claude Fable 5. Choose a model for each thread in the app builder's Chat tab. Admins can set the organization's default app building provider and model in the AI settings.
Claude Sonnet 5 can be used on paid plans with a Retool-managed key or your own key. The GPT-5.6 models and Claude Fable 5 require you to bring your own key, which is available on the Enterprise plan.
