Questions

What is Clef?

Clef is a family of decision models from Cloudflare. You give it a state (text, JSON, images or video) and a schema of typed questions, and it returns a probability for every allowed answer instead of free-form text.

What is the difference between Clef and Clef-Flash?

Clef-Flash is the fast 9B model ($0.09 per million input tokens). Clef is the larger 27B model ($0.24 per million input tokens). Both use the same API and question types.

What does “noul” mean?

A noul question is a yes/no question. The answer is a single number: the probability that the answer is yes.

How many images can I sort at once?

Up to 4 images per run, judged together in one model request. Larger batches are on the way.

Is this playground free?

It’s free to try: 3 runs per visitor, no sign-up. After that, a $9 pack gives you 20 runs that work here and in the image checker.

Is this an official Cloudflare site?

No. clefdecide.com is an independent site that calls Cloudflare Workers AI. It is not affiliated with or endorsed by Cloudflare.

Do you store what I type or upload?

No. Playground input is sent to Cloudflare Workers AI to produce the answer and is not saved by this site.
