# Limits & pricing

AI Search usage limits and pricing depend on your [Workers plan](https://developers.cloudflare.com/workers/platform/pricing/).

## Limits

The following limits apply based on your [Workers plan](https://developers.cloudflare.com/workers/platform/pricing/):

| Limit                           | Workers Free             | Workers Paid                 |
| ------------------------------- | ------------------------ | ---------------------------- |
| AI Search instances per account | 100                      | 5,000                        |
| Files per instance              | 100,000                  | 1M or 500K for hybrid search |
| Max file size                   | 4 MB                     | 4 MB                         |
| Queries per month               | 20,000                   | Unlimited                    |
| Maximum pages crawled per day   | 500                      | Unlimited                    |
| Max custom metadata fields      | 5 per AI Search instance | 5 per AI Search instance     |
| Max text metadata value length  | 500 characters           | 500 characters               |

Need a higher limit?

To request an adjustment to a limit, complete the [Limit Increase Request Form ↗](https://forms.gle/wnizxrEUW33Y15CT8). If the limit can be increased, Cloudflare will contact you with next steps.

## Pricing

During the open beta, AI Search is free within these limits. [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.

## Historical billing

Instances created before AI Search moved to managed infrastructure ran on Cloudflare services in your own account, so older invoices may include separate charges for [R2](https://developers.cloudflare.com/r2/pricing/), [Vectorize](https://developers.cloudflare.com/vectorize/platform/pricing/), [Workers AI](https://developers.cloudflare.com/workers-ai/platform/pricing/), [AI Gateway](https://developers.cloudflare.com/ai-gateway/reference/pricing/), and [Browser Run](https://developers.cloudflare.com/browser-run/pricing/).

After the move, storage, vector indexing, and Browser Run usage for crawling are included. Workers AI and AI Gateway are still billed separately.

If your instance crawled a website, those pages now live in built-in storage. The dedicated R2 bucket AI Search originally created in your account is no longer used. It remains in your account, and any objects left in it may still count toward [R2 storage usage](https://developers.cloudflare.com/r2/pricing/). AI Search no longer writes to this bucket, so you can delete it if you no longer need its contents.
