LicensePro

Runs a Workers AI model under a Cloudflare account, named as the string’s host or by CLOUDFLARE_ACCOUNT_ID. The model’s protocol sets what it does:

`protocol=`	Models	Runs as
`typesafe`	Decision models, such as Clef	`typesafe` does: navigator only, choosing among listed alternatives
`openai`	Chat models, such as `@cf/openai/gpt-oss-120b`	A chat provider, which also formats and writes

Without protocol=, a model under @cf/cloudflare/clef speaks typesafe and any other openai. A bare model name names one of Cloudflare’s own, so clef is @cf/cloudflare/clef.

Options

Option	On Cloudflare
`protocol`	`typesafe` or `openai`, from the model when absent
`gateway`	The AI Gateway each call goes through, as `CLOUDFLARE_GATEWAY_ID` names it
`vision`	A decision model is shown screenshots at `stall:3`. A chat model is off by default; `vision=true` opts in one that reads images
`body.<path>`	Chat models; fields OpenAI’s chat request names
`header`, `max_tokens`, `temperature`, `top_p`, `frames`, `timeout`	As listed; the chat options apply to chat models
