The AI21 Labs entry should distinguish historical API documentation from an available replacement. AI21's August 2026 notice directs applications away from Jamba and Maestro endpoints and announces a forthcoming platform.
For an affected application, keep a small, non-sensitive set of expected task outcomes and identify the endpoint dependencies. Confirm current access details through official channels before promising a drop-in migration. A sunset announcement alone does not document the replacement's complete request contract.
