Cloudflare releases Clairic, a single-pass document extraction model, in preview on Workers AI

TL;DR

Cloudflare has released Clairic, a model that extracts named fields from unstructured text in a single pass instead of generating tokens one at a time. It is in preview on Workers AI, with open weights promised soon. Cloudflare claims a multi-step agent chain using Clairic runs in 19.3 seconds, versus 61.7 seconds for GLM-5.3 alone.

Cloudflare has released Clairic, a document extraction model that answers every requested field in a single pass rather than generating text token by token. The model is available in preview on Workers AI, and Cloudflare says open weights will follow soon. No release date for the weights has been given.

How Clairic works

Users specify the fields they want, such as an order number or invoice total. Clairic returns a matching value for each field in the correct format, along with a confidence score. If a value is not present in the source text, the model returns null.

Because it is not an autoregressive text generator, Clairic does not produce free-form output. Beyond extraction, Cloudflare says it can handle simple calculations, estimates, and forecasts over the extracted values. It works on unstructured text and is designed as one component in a larger agent pipeline.

Chained with other "System One" models

Cloudflare positions Clairic to run alongside LLMs and other task-specific "System One" models, including one called Jev. Its example is a customer complaint email:

  1. Clairic extracts the order number, amount, and damage, then estimates the repair cost.
  2. Clef, a decision model, applies company rules to choose between a refund and a repair.
  3. GLM-5.3 writes the reply to the customer.

According to Cloudflare, this chain completes in 19.3 seconds. It says GLM-5.3 handling all three steps alone takes 61.7 seconds, roughly 3.2x longer, and costs almost twice as much. These figures come from Cloudflare and have not been independently verified. The workload, token counts, and hardware behind the comparison were not detailed.

Known limitations

Cloudflare says Clairic cannot yet reliably handle longer chains of calculations. For now, it advises developers to run those steps in their own code rather than relying on the model.

What this means

Clairic is a bet that much of what teams use LLMs for in document workflows, such as pulling fields, normalizing formats, and flagging missing values, does not need autoregressive generation. A single-pass design gives predictable latency and per-field confidence scores, which matter in production pipelines where a silent hallucination is costlier than a null.

The real test is accuracy, and Cloudflare has published no extraction benchmarks, parameter count, or context window. The 19.3 versus 61.7 second comparison measures a chain in which an LLM does all the work against one that offloads two steps, so it says little about Clairic's extraction quality in isolation. Teams should wait for the open weights and independent evaluations on their own document types before replacing an LLM-based extractor.

The stated limit on multi-step calculations also means Clairic suits narrow, well-defined extraction tasks, not general reasoning over documents. If the open weights ship with permissive terms, it could become a cheap default for the extraction stage of agent pipelines.
