# File upload limits

File upload limits record documented size, count, page, duration, frequency, and storage limits with their scope. Accepting one test file does not establish every limit.

Terminology basis: **Measured product property** — https://docs.x.ai/grok/faq.

## Current support at a glance

File upload limits: 9 supported, 0 partial, 0 unsupported, 22 unreviewed across 31 cataloged products.

- Reviewed current products: 9 of 31
- Supported: 9
- Partial: 0
- Unsupported: 0
- Unreviewed: 22
- Not applicable: 0

Unknown or unreviewed means insufficient published evidence; it does not mean unsupported.

File support is not operationally useful without its limits. This row records per-file bytes, files per message or run, pages per document, audio or video duration, image dimensions, project storage, rolling daily or hourly quotas, and any separate organization cap.

Every number needs a scope: format, plan, model, client, workspace, region, and review date. Evidence should also describe the failure mode—preflight rejection, asynchronous processing failure, truncation, sampling, or silent omission—and whether the harness shows remaining quota before an upload.
