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

26 models with downloadable weights you can self-host under their licenses (MIT, Apache 2.0, and Modified MIT). 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.

Frequently Asked Questions About Document Question Answering Models

Document question answering is the task of answering questions grounded in document images: invoices, forms, contracts, and reports. It layers three abilities: reading the text (OCR), understanding layout structure such as tables, key-value pairs, and reading order, and reasoning over both to locate the answer. Layout-aware transformers pioneered the recipe and modern vision language models now do it end to end from the page image. Benchmarks like DocVQA score answer accuracy. It automates data entry, claims and loan processing, compliance review, and contract analysis. This page lists 75 document question answering models, including 26 open-weight options you can self-host; all of them run live in the Playground so you can test them on your own images.

It depends on your task and constraints. For fixed categories in production, a model fine-tuned on your own data typically beats any general-purpose model. Compare the document question answering models on this page and try them on your own images to see which fits.

Yes. 26 of the 75 document question answering models here are open-weight (for example GLM 5.3 Flash, Qwen3.8 27B, and Muse Glimmer 30B), free to self-host under their licenses (MIT, Apache 2.0, and Modified MIT).
