Cloudflare's fast 9B open-weight decision model that returns probabilities for typed choice, score and yes/no questions about text or images
Clef Flash by cloudflare is offered by 4 providers on this page. No official API price is listed for it; the prices below come from third-party channels. The lowest paid channel is Melious at $0.034 / $0 per 1M. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it. Prices vary about 2.7× across the providers that host it.
The context window is 1,800 tokens at the reference host, but hosts report different limits, from 1,800 to 24,576, so the usable window depends on the provider you pick. It supports structured output. Accepted input modalities are Text and Image. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use.
