Release date: 26 October 2023
Released in Endpoints + DocumentUnderstanding + Data Extraction ML packages | v23.10.0
A new version for all out-of-the-box pre-trained ML packages is now available for general usage.
We are constantly working to improve your Document Understanding experience. For this release, we made sure to bring minor security and stability improvements to our product.
Release date: 3 August 2023
Released in DocumentUnderstanding + Data Extraction ML packages | v23.7.0
- In documents where a table runs across many pages, a table row (a line item) gets split across 2 pages, in some cases even more. The previous model versions assumed that each page break was also a row-break, and it broke items into multiple pieces. The current model version fixes this issue. To benefit from this feature in a workflow, you need to use the DocumentUnderstanding.ML.Activities package version 1.23.0-preview, and the 23.7.0 model version in that particular workflow.
- Models now have a faster prediction time per page, and use RAM more efficiently, allowing processing of larger documents.
Release date: 24 March 2023
Released in DocumentUnderstanding | v23.4.2
The UiPath Document OCR public endpoint has been updated and now provides handwriting language support for German and French, and print language support for Danish, Finnish, Norwegian, and Swedish. Here's the complete list of the new supported languages: Danish, Swedish, Norwegian, Finnish, Polish, Hungarian, Czech, Slovakian, Estonian, Latvian, Lithuanian, Slovenian, Croatian, Serbian, Turkish.
Release date: 10 May 2023
Released in DocumentUnderstanding + Data Extraction ML packages | v23.4.0
The UiPath Document OCR is now available as an out-of-the-box pre-trained package, and it is available for both GPU and CPU usage. This enables customers who prefer to avoid using public endpoints to deploy UiPath Document OCR in their own tenants, in an isolated environment.
A list of seven new Out-of-the-box pre-trained ML Packages is now available for general usage. Here's the list of the seven new models:
- Certificate of incorporation/Good Standing

Release date: 23 February 2023
Released in Endpoints + DocumentUnderstanding + Data Extraction ML packages | v23.2.0
What's new & improvements
A new version of the out-of-the-box pre-trained ML packages (23.1.0) and their public endpoints has been released, now using cutting edge LayoutLM Transformers based architecture, which is more powerful and increases accuracy overall, especially on column fields (tables).
This improvement has made the out-of-the-box pre-trained ML packages more powerful, meaning that you may experience longer latency for training and for predictions.
For all situations where latency is critical (e.g.: attended scenarios) we recommend deploying the models as ML Skills using a GPU.
We have improved how the scores are calculated after Training/Evaluation/Full pipelines to provide a separate score for each column field. Before this improvement, F1 scores were calculated as a whole, for all column fields taken together.
An upcoming removal is announced for the Manual edits feature used in the model evaluation. More information here.
Known issues
The project import from AI Center is currently disabled. We are actively working on this and expect to have it reenabled by the end of March.
Erratum 8 May 2023
Known issue
Fatal Python error: Segmentation fault is received when running a
Full or Training Pipeline. We recommend using the ML Packages with v23.4 until this
bug is fixed.
Erratum 20 April 2023
Overall score for all pipelines is now an Accuracy. Previously it was an F1 score. The evaluation artefacts in AI Center still contain both accuracy and F1 score, for backwards comparability.
Release date: 11 January 2023
Released in Endpoints and DocumentClassifier | v23.1.0
We have improved the F1 scores and they are now also displayed for Training pipelines.
The Artifacts folder has an updated list of artifacts.
The DocumentClassifier model now predicts 25 classes, instead of 26, due to the removal of the Delivery Notes class.
Release date: 13 December 2022
Released in endpoints + DocumentUnderstanding + Data Extraction ML packages | v22.11.0
This release brings significant improvements to the public endpoints of the out-of-the-box pre-trained ML packages, meaning that we are now using the latest LayoutLM based Deep Learning architecture.
This improvement provides better accuracy on all document types, especially for the Invoices model, and it also improves the accuracy on column fields and tables.
We added new extracted fields to the Invoices model that now have Shipping Date, Vendor email address, Bank name, Bank account number, IBAN, SWIFT Code, Bank Address, Bank Routing number, and Tax rate. You can check the list of extracted fields by accessing this page and clicking on the link available for each model.
Model scores are now returned by Training pipelines too, not only by Full or Evaluation pipelines.
F1 scores are now available for each column field. Until now, F1 scores were available only for all column fields taken together.

Release date: 7 March 2022
Released in UiPathDocumentOCR | v22.2.3
Superior capability
Integrated HandwritingRecognitionOCR into UiPathDocumentOCR. In many cases, there is a mix of fields. By integrating the handwriting reading capability, we are able to apply the correct recognition to each field: print recognition to print text, and handwriting recognition to handwritten text.
Altough HandwritingRecognitionOCR can detect any handwriting, please know that it is trained and optimized only for English.
Release date: 14 March 2022
Released in DocumentUnderstanding + DocumentClassifier + Data Extraction ML packages
| v22.1.6
Bug fixes
Fixed a bug that was causing a training pipeline or a full pipeline in AI Center to fail due to an ML package issue in data pre-processing for an empty line.
Release date: 2 March 2022
Released in DocumentUnderstanding + DocumentClassifier + Data Extraction ML packages | v22.1.4
What's new
The Utility Bills ML package is now generally available.
Improvements
Overall improved performance and scalability.
Significant improvements on scores when training on the new version of the DocumentUnderstanding ML package as compared to previous versions.
Dates in column fields are now parsed correctly.
Date parsing now recognizes Turkish month names.
Changes
Changed the behavior for Training Pipelines and Full Pipelines when training on GPU versus on CPU. The 21.10.x models trained on CPUs were smaller, so they trained faster than the previous versions, while having slightly lower accuracy than before.
This behavior has been reversed with this release, so the model being trained on GPU and on CPU is the exact same model, and the training speed has reverted to what it was before 2021.10, which means training on CPU is again 10-20X slower than on GPU.
Release date: 24 November 2021
Released in Data Extraction ML packages | v21.10.9
Fixed a bug that was throwing a prediction error at runtime.
Release date: 22 October 2021

InvoicesChina, DeliveryNotes, RemittanceAdvices, W2, and W9 ML packages are now in Public Preview. We recommend you check out these packages and start using them for the type of documents you need to process.
Improvements
Implemented document level evaluation. This is representative for the runtime performance in your RPA workflow.
Evaluation can also be done on datasets with fewer fields than the ML Package being evaluated. This facilitates evaluation on out-of-the-box pre-trained ML Packages.
eval.redo_ocr
needs to be set to true in the AI Center Evaluation Pipeline.
Training on CPU now uses a smaller model to obtain a 5x-7x speedup. However, you should expect a lower accuracy by 0-5% on CPU.
Evaluation.xlsx files produced by Evaluation
Pipelines.
The UtilityBills ML Package has been substantially improved.
Address parsing improvement for addresses which skip 1-2 lines of text.
Improvement on extracting negative values, very large values (11 digits or more), or dates far into the future.
