WORKERS AI

Cloudflare shipped Radar Researcher, a natural-language agent that answers questions about global internet traffic with real interactive charts. The architecture - MCP code mode, chart specs that never let the model touch raw numbers, and a three-model fallback chain - is the interesting part for developers.

Cloudflare published the serving playbook behind Workers AI running Moonshot Kimi K2.6 and Zhipu GLM 5.2: FP8 KV caches double Kimi's resident context to 1.37M tokens, INT4 weights shrink GLM 5.2's checkpoint 40%, and a page-tagging integrity check protects the shared cache at under 1% overhead. The numbers show what actually matters when open frontier models run on GPU fleets.
