Clef and Clef-flash: open decision models
Cloudflare publishes two typed output models for routing and classification in agent workflows.
Available
Facts, analysis and limits
Verified facts
- The models are available on Workers AI and announced under Apache 2.0 license on Hugging Face.
- They are compatible with Jev API and have a vision encoder and 64k context window.
- The decision-making mechanism scores the choices of the scheme rather than generating an intermediate token reasoning by token.
What changes
A structured decision can avoid mobilising a large generalist model for each branch of workflow.
Practical implication
Test routing, calibration and referral rate to a human on a real set of tickets.
Availability
Belgium/EEA: regional scope is not specified in the sources reviewed; check the account, contract and processing region before use.
Limits and uncertainty
New Clef release on October 1, distinct from Jev/Ollama support already covered in September. Benchmark scores are Cloudflare's.
