Cloudflare released Clef and Clef-flash, open-source decision models hosted on Workers AI that classify inputs and produce bounded structured outputs for agentic workflows. The models outperform competitors like Jev on benchmarks, support both text and images, and offer 2x faster latency than LLMs for decision-making tasks. Cloudflare also introduced a reinforcement learning product to fine-tune Clef for specific use cases.
