Highlights
Each model is specifically trained for Japanese document images, supporting the recognition of over 7,000 Japanese characters, including vertical text and other layout structures unique to Japanese documents. (It also supports English documents.)
Equipped with four AI models trained on Japanese datasets: text detection, text recognition, layout analysis, and table structure recognition. All models are independently trained and optimized for Japanese documents, delivering high-precision inference.
By leveraging layout analysis, table structure parsing, and reading order estimation, it extracts information while preserving the semantic structure of the document layout.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay by the hour for each host the document analysis model runs on. Pricing splits along two lines: instance type and inference mode. You choose from GPU instances (ml.g4dn.xlarge, ml.g5.xlarge, ml.g6.xlarge) and CPU instances (ml.c7i.xlarge, ml.c7i.2xlarge). Each instance runs in either batch mode, for processing large document volumes, or real-time mode, for on-demand requests. Not every instance offers both modes. Your total cost scales with the instance size you pick and how many host-hours you run. You add SageMaker instance charges on top.
Top-of-mind questions for buyers
What does one host-hour cover, and am I charged when the endpoint is idle but running?
One host-hour is one hour that a SageMaker endpoint instance runs the document analysis model. Charges accrue for every hour the instance stays active, even without incoming requests. Shutting the endpoint down stops software charges. You control this by deploying and deleting endpoints through the client tool.
How do the software charges combine with the SageMaker instance charges on my bill?
Two charges apply at the same time. You pay the per-hour software fee shown in the table for the model. You also pay AWS separately for the underlying SageMaker instance. Both meter the same running hours. Larger instance types and longer run times raise both charges together.
When should I pick batch mode versus real-time mode for an instance type?
Batch mode fits processing large document volumes in one job, such as directory or S3 bulk analysis. Real-time mode fits on-demand requests where you call the endpoint and get results back immediately. Each mode bills per host-hour. Not every instance type offers both modes, so check the table.

An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Real-time inference
Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference .
Batch transform
Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI .
