Cloudflare launches open-source decision models Clef and Clef-flash

By PulseAugur Editorial · [1 sources] ·

Cloudflare has released two open-source decision models, Clef and Clef-flash, designed for tasks like classification and choice selection without generating text. Built on Qwen3.8-27B and Qwen3.5-9B respectively, these models are compatible with the Jev API and are available on OpenRouter and Hugging Face. Initial tests suggest Clef models are faster than Jev, though Jev performs better on more complex reasoning tasks. AI

IMPACT These specialized decision models could offer more efficient and cost-effective solutions for classification and choice-based AI tasks.

RANK_REASON Cloudflare released new models, but they are specialized decision models rather than general-purpose frontier models.
