We haven't benchmarked document question answering yet; scores and rankings appear on this site only where we've measured them. Until then, compare the models below, and for fixed categories in production expect a model fine-tuned on your own data to win.

Open-Source Document Question Answering Models

29 models with downloadable weights you can self-host under their licenses (Custom, MIT, and Apache 2.0). All run live in the Playground through hosted APIs, so self-hosting is optional.

How to Choose a Document Question Answering Model

Document QA layers reading, layout understanding, and reasoning. The practical choice is between end-to-end VLMs and structured extraction pipelines, and it turns on whether your questions are fixed or free-form.

If you always want the same fields (total, date, account number), frame it as structured extraction: prompt a document-capable model for a JSON schema, validate the output, and route failures to review. Fixed schemas are easier to evaluate and monitor than free-form answers, and cheaper models handle them reliably.

When users ask arbitrary questions about arbitrary documents, a strong VLM reading the page image end to end is the practical choice: it handles tables, key-value layouts, and reading order without a custom pipeline. Accuracy drops on dense tables and long multi-page documents, so keep humans in the loop where errors are costly.

The bottom line: Fixed fields deserve a schema-based extraction pipeline with validation; free-form questions justify an end-to-end VLM, with review on high-stakes answers.
