ClefBench user guides

Learn the browser workflow, understand model results and find the evidence behind our comparisons.

ClefBench compares structured decisions from Clef, Clef-flash and Jev. These guides describe the website, its controls and its usage rules. They are not documentation for a public ClefBench API.

Start with the browser workflow

User guide: make your first comparison — enter text or JSON, define questions, select models and read results.
Open the playground — try a public example or a task you are allowed to share.
Understand subscriptions and credits — free sharing requirements, paid model access and usage examples.

Understand the models and the evidence

Cloudflare Clef guide — model variants, hosted limits and a recorded example.
Independent benchmark and methodology — fixed samples, reference answers and original results.
Confidence and human review — interpret probabilities without treating confidence as guaranteed accuracy.
Worked support-message example — inspect a real recorded model disagreement.

Integrating with a model provider

The playground's Copy request control exports an OpenRouter request body for each selected model. It does not create an API key or a public ClefBench endpoint. Use your own provider account and the provider's current documentation for integration.

The official API pricing page links to provider sources and separates their charges from the ClefBench subscription. Contact support for questions about this website.
