Clef: our open-source decision models

Cloudflare’s Clef introduces open-source decision models designed to make fast, structured classifications that can be embedded directly into business workflows, reducing latency and cost versus general-purpose LLMs. For CIOs, the strategic implication is a shift toward more deterministic, automatable AI decisioning for use cases like security triage, customer support routing, and operational escalation, with less dependence on human-in-the-loop handling. IT organizations should view this as a way to improve throughput and consistency while extending AI governance and model customization through a new fine-tuning platform.
