Bring your own key

Choose OpenAI or Anthropic. You pay that provider directly and can switch among its supported models whenever you like.

Your provider API key

Stored in your browser only and sent through Rulebase securely when you use AI.

Using Rulebase credit. Previously, purchased checks were fixed to GPT-5.5, so you could not switch models. You can now choose and switch between GPT-5.5, GPT-5.6 Sol, Terra, and Luna whenever you need to. Sol is the flagship, full-rate option; Terra balances capability with lower-cost checks; Luna is the lowest-cost option and can make your balance go furthest. The selected model handles each check, and measured use comes from your Rulebase balance. Add your own provider key to pay that provider directly instead.

Model

Switch freely between the supported frontier models for the selected provider.

First checks may cost more while Rulebase guidance is loaded; later checks in the same session are usually cheaper.

Buy AI Checks

No API key needed — $10 gets you around 35 GPT-5.5 checks. After purchase, Terra and Luna can make the same balance go further.

Free checks

GPT-5.6 choices

Previously, purchased checks were fixed to GPT-5.5, so you could not switch models. With purchased Rulebase credit, you can now choose and switch between GPT-5.5 and the GPT-5.6 models in AI Settings. Your selection handles each check, and each check draws from your balance according to its measured use. Terra and especially Luna use lower-cost tiers, so purchased checks can go further than with the full-rate option; exact use varies by check.

Sol: — the flagship, full-rate GPT-5.6 option.
Terra: — a lower-cost balance of capability and value.
Luna: — the lowest-cost option, designed to stretch a purchased balance furthest.
