## Which one, for what

### Clairic (B)

Good for: Typed fields, estimates and next-step forecasts from emails, invoices, receipts and other text or images inside Cloudflare, each with a null probability and confidence.

Ahead on:
- Agent ergonomics, 78 against 70
- Payments & pricing, 40 against 20

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Preview only. Cloudflare calls the endpoint an early checkpoint and expects to replace it under the unversioned ID `@cf/cloudflare/clairic`

### 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 51
- Security & auth, 80 against 72
- Maintenance & community, 80 against 57
- Transparency & trust, 90 against 80

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

## Verdicts

**Clairic.** Clairic's price is public at $0.10 per million input tokens with no output charge, and its docs publish JSON Schemas, limitations and when to use a decision model instead. It is a preview that Cloudflare calls an early checkpoint, served under an unversioned ID with no SLA, and its promised open weights have no date or licence.

**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.

## Before you call either

### Clairic

1. Send `model` as `clairic` in the body as well as in the URL. The input schema requires `model` and `fields`
2. Set `reference_date`, or add a line giving today's date to the state, for any field that depends on the current date
3. Treat a null `value` as not found, and read `p_null`, `confidence` or the 80% interval before acting. Typed output is well formed, not necessarily correct
4. Extract the inputs and do multi-step sums and table totals in code. Cloudflare says long arithmetic chains aren't reliable yet
5. Embed images as data URLs or base64 objects, at most four, 4 MiB each and 8 MiB in all. Remote image URLs are refused
6. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent, 3040 means capacity, so retry later

### 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
