Cloudflare Workers AI

Cloudflare documents regional controls for Workers via Data Localization Suite: Regional Services can ensure processing of a Workers project occurs only in-region for a custom domain, but this does not apply to subrequests or other triggers. For Developer Platform compatibility, Cloudflare states Workers AI supports Customer Metadata Boundary EU, but Jurisdictional Restrictions (data location/storage) are not supported today, and Workers AI analytics datasets are an exception that are supported. Cloudflare also describes Workers AI as running on GPUs on Cloudflare's global network.

Cloudflare states Workers AI customer content is not used to train models or improve services without explicit consent. Customer content may be stored only if the customer uses storage services such as R2, KV, Durable Objects, or Vectorize with Workers AI. Cloudflare's general privacy policy says personal information is retained for as long as needed for business purposes and legal obligations. Workers Logs retention is 3 days on Free and 7 days on Paid plans if logs are enabled.

Workers AI inputs, outputs, embeddings, and training data are treated as Customer Content. Cloudflare says it does not make that content available to other customers and does not use it to train AI models made available on Workers AI or to improve Cloudflare or third-party services unless it receives explicit consent.
