What clef costs

Provider prices per 1M tokens, updated October 5, 2026.more

These are the upstream provider rates. Pay as you go adds 5%, or 0% if you bring your own keys, and there is no per-request fee. Prompt caching and routing change what you pay against these rates, not the rates themselves.

clef questions

How much does clef cost?

clef is priced at $0.24 per million input tokens and free per million output tokens when accessed via Requesty. Those are the upstream provider rates: pay as you go adds 5% on top, or 0% if you bring your own provider keys.

What is the context window of clef?

clef has a context window of 66K tokens. That's roughly 87 words of input you can fit in a single prompt.

What can clef do?

clef supports vision input. You can call it through any OpenAI-compatible client by pointing base_url to Requesty.

How do I use clef with the OpenAI SDK?

Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "cloudflare/clef". The Quickstart above shows Python, JavaScript and cURL snippets.

Can I run clef through Requesty?

Yes. clef runs through Requesty's OpenAI-compatible API, served from Cloudflare, Inc.. You do not host the model yourself: point base_url at Requesty, set the model to "cloudflare/clef", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
