# Limits & pricing

Instances created after **April 16, 2026** include [built-in storage](https://developers.cloudflare.com/ai-search/configuration/data-source/built-in-storage/), a [built-in vector index](https://developers.cloudflare.com/ai-search/configuration/indexing/vector-search/#built-in-vector-index), and web crawling. You can see if your instance was created after the new release by checking if it has built-in storage and vector index. You can check by going on the dashboard under **AI** \> **AI Search**. Select your instance and check the **Overview** tab to see if it includes built-in storage and built-in vector database.

## New instances

If your instance was created after **April 16, 2026**, it includes built-in storage, a built-in vector index, and web crawling. During the open beta, AI Search is free within the limits below. [Workers AI](https://developers.cloudflare.com/workers-ai/platform/pricing/) and [AI Gateway](https://developers.cloudflare.com/ai-gateway/reference/pricing/) usage is billed separately. Pricing details will be communicated at least 30 days before any billing begins.
