// The short answer

Which Azure service should you use?

Use Azure Content Understanding if you are paying for OCR or layout at volume, if a meaningful share of your files are digital Word, Excel or email documents, or if you also need to process audio and video. It is 33% cheaper for OCR, 50% cheaper for layout, and 150 times cheaper on digital files, because it bills those on a Minimal meter at $0.01 per 1,000 pages instead of running OCR they never needed. Stay on Azure AI Document Intelligence if you need a flat and forecastable per-page rate, if you send documents longer than 300 pages, if you route high volumes through the $3 per 1,000 pages classifier, or if the prebuilt invoice and W-2 models already return what you need. Microsoft has not deprecated Document Intelligence, has announced no end of support, and its meters are still live, so there is no deadline forcing this decision.

The structural difference

Document Intelligence is a self-contained service: one call, one per-page rate, one bill.

Content Understanding is an orchestration layer that runs generative work on a Foundry model deployment you provision. Those tokens are billed to that deployment, not to the service.

Cheaper at the meter. Two bills. And a cost that moves with the model you pick.

// Setting the record straight

Is Content Understanding replacing Document Intelligence?

No. Microsoft has announced no end of support for Azure AI Document Intelligence, and every one of its billing meters is still live and active in the official Azure price feed, including meters that took effect as recently as January 2026. The service is being sold and supported.

What is genuinely true, and worth acting on, is narrower: two preview API versions of Content Understanding are being retired. That is a Content Understanding deadline, not a Document Intelligence one, and the two keep getting conflated in blog posts. Nothing on the Document Intelligence side has a published sunset.

The one real deadline

Content Understanding API versions 2024-12-01-preview and 2025-05-01-preview are being retired on July 15, 2026.

The generally available version is 2025-11-01. If your code still points at a preview endpoint, move it now. The GA release also changed how generative features are billed, so re-check your cost model while you are in there rather than assuming the old estimate still holds.

Document Intelligence has no equivalent deadline. If you are on it and it works, you are not on a clock.

When Content Understanding is worth the move

You are paying for plain OCR or layout at scale

This is the clearest win. The same OCR is $1.00 per 1,000 pages instead of $1.50, and layout is $5.00 instead of $10.00. On 5 million pages of layout a year, that is $25,000 rather than $50,000, for identical work.

A lot of your input is digital, not scanned

Word, Excel, PowerPoint, HTML, text and email files bill on the Minimal meter at $0.01 per 1,000 pages, because no OCR is performed. Document Intelligence has no digital meter and charges the full Read rate of $1.50 to read a file that was never a scan. That is a 150-fold difference.

Your layouts are irregular and a trained model keeps missing

Content Understanding lets you define a schema in JSON and improve it with a handful of labeled examples in context, without retraining anything. On documents that vary by supplier or by state, that iteration loop is far shorter than training and redeploying a custom model.

You need confidence scores you can act on

Confidence scores and source grounding, tracing every field back to where it appeared on the page, are first-class output. If a human reviews low-confidence fields, that is the signal that decides what reaches them.

Your content is not only documents

Audio and video content extraction is not something Document Intelligence can do at any price. If call recordings or video sit in the same pipeline as your documents, one service now covers all of it.

// Stay put

When Document Intelligence is still the right answer

A cheaper meter is not automatically a cheaper project. Four cases where the older service is genuinely better, not just familiar.

You need a flat, forecastable per-page cost

Document Intelligence publishes a rate for every model and bills nothing else. Content Understanding's generative cost moves with your schema, your feature flags and the model you attach, which is harder to put in a budget.

You send documents longer than 300 pages

Content Understanding caps a single document at 300 pages and 200 MB. Document Intelligence takes 2,000 pages and 500 MB, the highest single-call ceiling of any major vendor.

You classify and route high volumes

The Document Intelligence classifier is $3.00 per 1,000 pages, flat. On Content Understanding, categorization is a generative feature, so it costs contextualization plus model tokens on every page you route.

The prebuilt models already fit your documents

If your invoices, receipts, W-2s and 1099s already come back correctly from a Document Intelligence prebuilt model at $10.00 per 1,000 pages, a migration buys you very little and adds a model deployment to run.

// Frequently asked

Content Understanding vs Document Intelligence: FAQ

Is Azure Content Understanding replacing Document Intelligence?
No. Microsoft has announced no end of support for Azure AI Document Intelligence, and its billing meters are still live in the official Azure price feed. Both services are sold, supported and updated. Content Understanding is a newer, broader service that also handles audio, video and images, but it is an addition to the lineup rather than a declared successor. Anyone telling you Document Intelligence is dead is speculating.
What is the difference between Content Understanding and Document Intelligence?
Document Intelligence is a self-contained document service: you call it, it returns fields, and it bills you one per-page rate. Content Understanding is a multimodal orchestration layer that runs generative features on a Foundry model deployment you provide, so it also reads audio, video and images, and it returns confidence scores and source grounding as first-class output. The trade is that Content Understanding gives you two bills instead of one.
Should I migrate from Document Intelligence to Content Understanding?
Migrate if you are paying for plain OCR or layout at scale, because Content Understanding is 33% to 50% cheaper on those meters, or if you process a lot of digital Word, Excel and email files, where it is 150 times cheaper. Stay on Document Intelligence if you need a flat forecastable rate, if you rely on the prebuilt invoice or W-2 models, if you use the $3 per 1,000 pages classifier, or if you send documents longer than 300 pages.
Which is cheaper, Content Understanding or Document Intelligence?
Content Understanding is cheaper on every content extraction meter: $1.00 per 1,000 pages for OCR against $1.50, $5.00 for layout against $10.00, and $0.01 for digital files against $1.50. Structured field extraction is the exception, because Content Understanding has no flat rate for it. Microsoft's own invoice example lands at $8.37 per 1,000 pages on a small model, against a flat $30.00 for Document Intelligence custom extraction, but a large model pushes the same job to about $33.00.
Does Content Understanding have prebuilt models like invoice and receipt?
It ships prebuilt analyzers such as documentSearch, invoice, callCenter, imageSearch and videoSearch, but the model is different. Document Intelligence gives you a fixed, trained model with a fixed schema and a flat per-page price. Content Understanding gives you a schema you define in JSON, executed by a generative model you supply, which is more flexible on unusual layouts and less predictable in cost.
What are the Content Understanding page and file size limits?
A single document can be up to 200 MB and 300 pages. Digital and text files are capped at 1 million characters, and plain text or email files at 1 MB. Throughput on the standard S0 tier is 1,000 pages or images a minute and 3,000 operations a minute. Document Intelligence accepts far longer files: 500 MB and 2,000 pages in one call.
When do the Content Understanding preview APIs retire?
API versions 2024-12-01-preview and 2025-05-01-preview are being retired on July 15, 2026. The generally available version is 2025-11-01. If your code still targets a preview endpoint, it needs to move to the GA version, and the GA release also changed how generative features are billed, so re-check your cost model at the same time.
Which models does Content Understanding support?
You bring your own Foundry deployment. Microsoft currently lists GPT-5.2 and the GPT-4.1 family (gpt-4.1, gpt-4.1-mini, gpt-4.1-nano) for chat completion, plus text-embedding-3-small, text-embedding-3-large and text-embedding-ada-002 for embeddings. Note that the GPT-4.1 family is scheduled for retirement in October 2026, so new work should target GPT-5.2.
Can Content Understanding process audio and video?
Yes, and this is the clearest capability gap between the two services. Content Understanding extracts content from audio and video, billed at $0.36 and $1.00 an hour respectively, with speech to text, speaker diarization, shot detection and frame sampling at roughly one frame per second. Document Intelligence handles documents only and has no audio or video capability at all.
Does Document Intelligence still have anything Content Understanding does not?
Three things that matter. A 2,000-page ceiling per call against 300. A flat, forecastable $30 per 1,000 pages for custom extraction with no second model bill. And a dedicated document classifier at $3 per 1,000 pages, which on Content Understanding becomes contextualization plus generative model tokens. For high-volume routing of long documents on a fixed budget, the older service is still the cleaner answer.

Both services hand you a JSON response, not a workflow

Whichever Azure service you land on, the output is an API response. Routing each document to the right analyzer, reviewing the fields the model was unsure about, applying your validation rules and pushing the result into your accounting system or ERP are all still yours to build and maintain. On most projects that work costs more than the meter ever will.

DocuOCR charges more per page, roughly $14 to $20 per 1,000, and ships that pipeline finished. If your team would rather own the integration, an Azure API is the cheaper path. If not, this is what the alternative looks like.

Compare the output, not the rate card
