What is Clef
Clef is an open-source decision model from Cloudflare. It is a 27B multimodal model that turns a state and a schema of typed questions into decisions, reading states as text, JSON, images, or video and returning a probability for every allowed option of every question in a single forward pass. No free-form text generation or output parsing is involved, and the Clef API is fully compatible with Jev and SystemOne.
Key Features
Use Cases
- High-speed classification tasks
- Agentic workflows that require structured decisions
- Fine-tuning decision models on custom data via reinforcement learning
Why do startups need this tool?
Startups building classification or agentic workflows can use an open-source decision model that returns structured probabilities in a single forward pass, avoiding free-form text generation and output parsing, with the option to fine-tune on their own data.
