Frequently asked questions
Free access, setup, and what to expect.
Clef is available with up to 10,000 neurons / day free through Cloudflare. Free allowances can change. Check the Clef provider limits before you start.
To use Clef, choose one of the listed Clef API providers and follow the provider’s account and API-key setup guide. Copy the Clef model ID and connection settings for your chosen provider into your app or API client. Model IDs can differ between providers. API requests go directly to the provider; Free Models is a comparison site.
Clef accepts text and image as listed input formats. Listed output formats include decisions. Image or audio input support does not imply image or audio generation. Check the chosen provider’s Clef documentation for supported file types and request formats.
Clef has a listed context window of 66K tokens. Tokens are small pieces of content rather than a word count. Instructions, conversation history, and other inputs use context space, and the response also needs room. The maximum output length for Clef may be smaller than the context window and can vary by provider.
Neither reasoning nor tool calling support is listed for Clef. Reasoning enables additional processing for complex problems. Tool calling allows a model to request functions that your app executes. Check the chosen provider’s documentation for capability availability and setup.
No benchmark results are listed for Clef yet. Missing scores don’t establish poor performance.

Evaluate Clef on examples from your own task alongside context size and provider limits.
