New AI Search<\/a> instances created after today will work differently. New instances come with built-in storage and a vector index, so you can upload a file, have it indexed immediately, and search it right away.<\/p>\n

Additionally new Workers Bindings are now available to use with AI Search. The new namespace binding lets you create and manage instances at runtime, and cross-instance search API lets you query across multiple instances in one call.<\/p>\n

Built-in storage and vector index<\/h4>\n

All new instances now comes with built-in storage which allows you to upload files directly to it using the Items API<\/a> or the dashboard. No R2 buckets to set up, no external data sources to connect first.<\/p>\n

Namespace binding<\/h4>\n
The new ai_search_namespaces<\/code> binding replaces the previous env.AI.autorag()<\/code> API provided through the AI<\/code> binding. It gives your Worker access to all instances within a namespace<\/a> and lets you create, update, and delete instances at runtime without redeploying.<\/p>\n
