It reads a state — text, JSON, an image or a video — and answers typed questions with probabilities: yes/no, a choice between options or a score. 32K-token context. Models run on GPUs that are started on demand, so the first request after a quiet spell waits for a worker to boot — usually one to five minutes. Everything after that answers in seconds.

Clef Flash

Cloudflare

It offers adjustable reasoning, parallel tool calls and schema-conforming JSON, and suits latency-sensitive uses such as search agents, voice pipelines and coding sub-agents. Text only, with a 260K-token context.
