Cloudflare this week: Workers AI retirements

Transcript

Workers AI models on the retirement list will fail with errors from November 20. Plus AI Search billing, AI Gateway authentication, Durable Object retries, and four more Cloudflare updates this week.

The date moved from November 15, 2026, and calls to the listed language, image, speech and embedding models will then fail.

AI Search billing is postponed to December 1, and the default sync interval changes from 6 to 24 hours.

AI Gateway now requires new gateways to enable authentication, and the API rejects turning it off later.

Durable Object calls now retry fetch and RPC up to four times within 10 seconds, and the retry limit accepts 0 to 10.

The Workers module registry will be the default for compatibility dates from November 17, and a legacy flag opts out.

Browser Isolation has a preview option to allow read-only actions, blocking data entry while keeping find, copy, print and zoom.

Private load balancers now support hash endpoint steering and session affinity, so each user stays on the same endpoint.

Account Abuse Protection now shows which recognized AI assistant made login or sign up requests, and for which account.

That's your week in Cloudflare. If this affects you, check the details before November 15, 2026.
