Model catalog
Which models vote on your claims
Up to 4 models from different providers vote on every claim you check. A separate judge model weighs their reasoning into one verdict. These are the models you can put on your panel. Each adds its credit weight to the per-claim price, so the quote reflects the panel you chose.

How the panel works
- Panel votes. Each model on your panel checks every claim on its own. In Model Fact-Check it argues from its own knowledge. In Live Research it searches the live web and cites its sources.
- A separate judge. Claude Opus 5 reads the panel's votes, reasoning, and evidence and writes one consensus verdict with a calibrated confidence score. Organization admins can pick a different judge.
- An adversarial challenger. When the panel is unanimous and confident, a cheap model that is not on the panel tries to refute the verdict before we confirm it. If it finds a dissent, the claim goes to the full judge.
- Spell & grammar (Tier 1) runs on a fixed fast model (Gemini 3.8 Flash) and isn't part of the picker.
