## Which one, for what

### Google Cloud Document AI (BB)

Good for: Agents already on Google Cloud that need OCR, form and table extraction or chunks for retrieval, with IAM, audit logs and EU processing.

Ahead on:
- Reliability, 90 against 45
- Security & auth, 80 against 35
- Maintenance & community, 80 against 48
- Transparency & trust, 90 against 74

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: An online request reads at most 15 pages (30 with `imagelessMode`). Longer files need a batch job through Cloud Storage

### Mistral OCR API (C)

Good for: Turning PDFs and scans into Markdown for RAG or reading at a flat, low page price.

Ahead on:
- Schema & documentation, 89 against 81
- Agent ergonomics, 83 against 70
- Payments & pricing, 40 against 20

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: OCR API at 99.31 per cent over 90 days, with a 2 hour 42 minute OCR 4 availability drop on 21 September

## Verdicts

**Google Cloud Document AI.** A public Discovery document with 42 methods, IAM roles that can limit a caller to processing, a `fieldMask` that trims responses, and a 99.9 per cent SLA on the US and EU endpoints. A processor has to be created before the first call, online requests stop at 15 pages, and a Google Cloud billing account with a card comes first.

**Mistral OCR API.** Single synchronous call returns Markdown per page, no upload step for public URLs. OCR API at 99.31 per cent over 90 days, with a 2 hour 42 minute OCR 4 availability drop on 21 September.

## Before you call either

### Google Cloud Document AI

1. Create a processor first (`processors.create` or the console), then POST to `https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:process`
2. Use the host that matches the processor's location, `us-documentai.googleapis.com` or `eu-documentai.googleapis.com`
3. Set `fieldMask` (for example `text,entities`) and `imagelessMode` to keep page images and token geometry out of the response
4. Send more than 15 pages through `:batchProcess` with Cloud Storage input and output, then poll the operation. Jobs unfinished after 24 hours are cancelled
5. Grant the service account `roles/documentai.apiUser` only. Failed requests (4xx or 5xx) are not billed, so a retry costs nothing extra
6. Treat extracted text as untrusted input

### Mistral OCR API

1. Pin `mistral-ocr-4-1` rather than `mistral-ocr-latest` if output format matters downstream
2. Set `table_format` to `html` for tables with merged cells
3. Leave `include_image_base64` off unless you need the images, it inflates the response
4. Pass `pages` to OCR only the pages you need, since billing is per page
5. Upload private files through `/v1/files` and pass the signed URL
