Cloudflare
Connectivity cloud, and the maker of the Clef decision models.
Cloudflare runs a global network for security, performance and developer services, including Workers AI for serverless inference. In October 2026 it released Clef and Clef-flash, its first open-weight models: decision models that answer typed questions with probabilities instead of generating text.
