Description
Clef and Clef-flash are open-source decision models built by Cloudflare, hosted on Workers AI for high-speed classification and agentic workflows. Alongside them, Cloudflare is launching a reinforcement learning fine-tuning platform that lets developers fine-tune decision models using their own data.

Could you build this?
No Training custom fast-classification/decision models and building an RL fine-tuning infrastructure platform on edge compute requires foundational ML research, model architecture design, and specialized infrastructure engineering.
What it would actually take: Building Clef requires training compact transformer/decision architectures (or distilling larger models) with custom tokenizers and fast inference kernels. The fine-tuning platform requires a distributed RL training pipeline (e.g., PPO or DPO), orchestration across GPU clusters, and an ultra-low-latency runtime integrated into edge workers (like Cloudflare Workers / V8 isolates). This demands deep machine learning research expertise and massive compute infrastructure.
