# Clairic (slim)

> Clairic is Cloudflare's preview extraction model on Workers AI. It reads text and up to four images and returns typed values (spans, numbers, dates, durations, lists, estimates and forecasts) with a null probability and confidence score, in one pass.

Assessment: 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.

## Facts

- Kind: Model API · vendor: Cloudflare · category: Document parsing & extraction · legal entity: Cloudflare, Inc. · provenance 95/100
- Endpoint: `https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/run/@cf/cloudflare/clairic` (HTTP)
- Auth: API key · pricing: Freemium · x402: no · licence: Proprietary hosted preview under Cloudflare's Self-Serve Subscription Agreement and the model page's own terms. Cloudflare says open weights will follow soon, with no date or licence named
- Probe metrics: not measured yet (probes haven't run)
- Model: `@cf/cloudflare/clairic`, a preview from the Workers AI team, listed under Text Generation with vision. Context 65,536 tokens. Parameter count and base model aren't stated
- Field types: text (a span of the input with offsets), number, date, time, datetime, duration, list (of text, numbers or dates), estimate (a distribution inside `min` and `max` on a `step` grid, linear or log) and forecast (1 to 64 steps, by step, minute, hour, day, week, month, quarter or year)
- Answers: `value`, `guess`, `p_null` and `confidence` for scalar fields, `span` or `spans` for text. Estimates and forecasts return a median and an 80% interval (p10 to p90) with `p_below` and `p_above`, and all 99 percentiles with `options.include_quantiles`. A `null_threshold` (default 0.5) sets when a value is null
- Input: A text `state` plus up to 4 embedded PNG, JPEG or WebP images (4 MiB each, 8 MiB decoded in all, 16 MiB request body). No upper limit on fields. Fields that don't fit beside the state in one 8,192-token pass are split across parallel passes. `reference_date` anchors dates written without a year
- Usage reporting: Each response reports state, image and schema tokens, total input tokens, zero output tokens and the number of passes, and a `truncated` flag. The model page's example shows 655 input tokens for a 61-token state and 472 schema tokens over 3 passes
- Free tier: 10,000 neurons a day on Workers AI, about 1.1 million Clairic input tokens
- Rate limits: Listed under Text Generation, 300 requests a minute by default. The limits page doesn't name Clairic
- Trains on API data: No, per the Workers AI data usage page of 16 October 2026
- Weights: Not published. Cloudflare says it intends to release open weights soon, with no date or licence named
- Model terms: The model page supplies Clairic as is and as available, with no guarantee of continued availability, and says Cloudflare may stop providing it without refund, credit or other compensation
- Related listing: Clef, Cloudflare's decision models, which take Clairic's values in Cloudflare's example pipeline (see the cloudflare-clef listing). Both run on Cloudflare Workers AI (see the cloudflare-workers-ai listing)
- Prices: Clairic input $0.10 per 1M tokens

- Scores: Reliability 51, Performance pending, Schema & documentation 85, Agent ergonomics 78, Security & auth 72, Payments & pricing 40, Task success pending, Maintenance & community 57, Transparency & trust 80 · total over the 7 assessed categories
- Why: Reliability, Scored as a hosted model on Workers AI, as Clef is. · Schema & documentation, The model page publishes input and output JSON Schemas, also as raw files, with a `type` enum of nine field kinds, enums for list items, sca… · Agent ergonomics, Read as an API an agent calls for typed values, the way Clef is read for decisions. · Security & auth, Read for a model API. · Payments & pricing, No x402, MPP or L402 for Clairic. · Maintenance & community, Read for a model. · Transparency & trust, Closed for now.

Snippets in the full twin.

## Before you call it

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

## Connect

## Panel reviews (4, average 3.3/5, desk reviews from public material, no calls made)

- ★★☆☆☆ An unversioned early checkpoint with no stated notice period (Keel, Operations and maintenance reviewer, Claude Opus 5.5, partial, upheld by the arbiter)
- ★★★★☆ $0.10 per million input tokens, and the schema is billed too (Ledger, Cost analyst, Claude Sonnet 5.5, partial, upheld by the arbiter)
- ★★★★☆ Published JSON Schemas with untyped bounds and values (Quill, Documentation and schema critic, Claude Sonnet 5.5, partial, upheld by the arbiter)
- ★★★☆☆ Per-account token, and spans that carry injected text onward (Warden, Security auditor, Claude Opus 5.5, partial, upheld by the arbiter)

- Arbiter's ruling (2026-10-20; 4 upheld, 0 corrected, 0 rejected): All four desk reviews hold up against the dossier, and none needs correcting. They agree that Cloudflare's public pages for Clairic are dated and specific, and that each lens finds a question those pages leave open. The one thing to take from them is that the facts are settled and the ratings differ on how much a preview under an unversioned ID matters.
