What's new in MOSTLY AI
v113
Sep 14th, 2023
Auto-adding of child tables
When you add database tables to a synthetic dataset, MOSTLY AI now also automatically adds all related child tables. You no longer need to add related tables manually.
Better guidance for _RARE_
values
You can now find more explanation about _RARE_
values after you hover over each in the preview of synthetic samples in the Summary page.
Improvements in handling nested table relationships
For multi-table setups with a 3-level hierarchy, any correlation between the 3rd level entities and all the 2nd level entities, that link to the same subject, are now retained. For example, for a User
> Order
> Item
setup, all Items
now retain correlations to all other Orders
that belong to the same User
.
Resolved issues
We resolved an issue with the use of the Numeric:Auto encoding type which caused the generation of synthetic datasets to fail for very large or very small datasets.
v112
Aug 31st, 2023
Welcome, Synthetic datasets! (Goodbye, Jobs)
Synthetic datasets is why you use MOSTLY AI! High accuracy, high data quality, privacy-protected synthetic datasets.
We want you to focus on generating synthetic data and we are adding the term to the top-level menu in the MOSTLY AI Synthetic Data Platform!
With that, we also want to say goodbye to Jobs. You served our users well and we are thankful for it!
Source and destination connector types
You can now define each connector as either a data source or a destination. That way, you can only select destination connectors for your synthetic dataset destination and prevent the risk of selecting a data source as the destination.
New design for synthetic datasets summary
When you now open a synthetic dataset from the new Synthetic datasets tab, a new summary page provides easier access to the preview of sample data, the QA report, the tracking of the synthetic dataset progress, and the configuration of the synthetic dataset.
You can use the sidebar on the right to quickly access each section.
- Overview
- Sample data
- QA Report
- Logs
- Configuration
Numeric (Auto) encoding type
The new encoding type Numeric (Auto) is now auto-assigned to columns that contain numeric data. Numeric (Auto) uses heuristics to automatically assign the relevant one of the available Numeric encoding types: Discrete, Digit, or Binned.
You no longer need to worry about which Numeric encoding type you need to use. Just select Numeric (Auto).
v111
Aug 17th, 2023
New Numeric encoding types
You can now select from three different Numeric encoding types: Digit, Discrete, and Binned.
For more information, see Numeric encoding type.
Preview of synthetic data is now available for shared jobs
The Synthetic data tab in a completed job is now available on shared jobs. When you share a link to a completed job with your team, they can now access the Synthetic data tab in the job and preview the generated synthetic data in the job.
Drop tables in the destination
The new option Drop tables in the destination in the Output settings will drop any tables that match the names of the tables in your synthetic data job. MOSTLY AI drops the tables at the start of the job before it completes AI model training and data generation.
You can enable Drop tables in the destination after you start a new job and select a database connector as the destination. The option is not available for cloud storage connectors.
Search database tables when adding them to a catalog
In v110, MOSLTY AI introduced a drop-down to add tables from a database. You can now enter a search term in the drop-down to filter the list of tables and more easily find the table you want to add.
v110
Aug 3rd, 2023
Support for multiple tables in ad hoc and cloud storage jobs
You can now create and configure multi-table jobs not only with databases, but also with file uploads and cloud storage catalog jobs.
New Tables tab in job configuration
For each job configuration, the new Tables tab gives you a list of all tables in the job. The Tables tab is also the new home of all training settings that were previously available in the Training settings tab. Moving forward, the Training settings tab will be no longer available.
In the Tables tab, you can now also add and remove tables from a job.
When you start a job, the Tables tab opens and contains no tables. You can add new tables with the Add table button. This action is supported in all job types: ad hoc, database catalogs, and cloud storage catalogs.
Easier database catalog creation flow
With the new database catalog flow, you no longer need to identify subject tables and rank them.
After you select a database connector, MOSTLY AI shows the new Tables tab where you can now add tables from your cloud buckets or databases and remove any tables that you no longer need.
Easier configuration of table relationships
You can now use the Foreign key option in Generation method to define relationships between tables. This is now available in the Data settings tab during job configuration.
To mark a table as a linked table, specify which of its columns is set as a Context foreign key to another table.
Table relationships configuration is no longer required to start a job
You can now start a job with two or more subject tables. You no longer need to define a relationship and mark any of the tables as a linked table.
Reference tables are now only available in old catalogs
With v110 of MOSTLY AI, the concept of reference tables is no longer available for any newly created jobs or catalogs. All tables in a job are either a subject table (by default) or a linked table (after you set a foreign key to another table). You can only view reference tables in catalogs that you created before v110.
However, you can no longer change the configuration of reference tables, such as set any primary or foreign keys.
Updates in Generate more data
You can now use Generate more data for all job types including database catalog jobs.
With the capability to have ad hoc jobs with multiple uploaded subject tables, for such jobs you will now need to specify the number of new generated subjects or provide a table seed for every subject table in the job.
Resolved issues
- MCD-2071 Implemented better precision when handling primary keys
v109
Jul 19th, 2023
Use different types of data sources and destinations for the same job
Regardless of the type of data source you use for your original data, you can now deliver the generated synthetic data into any type of destination that suits your downstream tasks.
You can now select a different type of connector for the delivery of your synthetic data, so you can mix and match, such as use original data from Databricks but deliver the synthetic data into Snowflake, or use original data from a Microsoft SQL Server database and deliver the synthetic data into a PostgreSQL database.
v108
Jul 6th, 2023
Preview generated synthetic data
When a synthetic data job completes, you can now preview the first up to 100 samples from each generated synthetic table.
Share links to generated synthetic data
With MOSTLY AI, you can now share links to completed synthetic data jobs with anyone. Send the links to colleagues or data-minded friends and they can download the generated synthetic data and review all available QA reports.
Improved star schema support with better handling of correlations between linked tables
We improved the support of star schemas and now provide better handling of the correlations between linked tables. In such cases, synthetic linked tables with correlations now have better quality and accuracy.
SSL support in PostgreSQL connectors
You can now configure your PostgreSQL connectors to use secure SSL connections to the database.
Job progress is now updated every second
As you track the progress of a running job from the Jobs tab or in the View tasks drawer, the progress is now updated every second to provide a more responsive experience.
Resolved issues
- MPD-3220 - In the previous version, when you clicked Stop generation while looking at a job progress in the View tasks drawer, the job would continue generating data and ignore the action. We have now resolved this issue and clicking Stop generation now takes immediate effect.
- MCD-1952 - When a column is set as both a primary key and a foreign key in the original data, MOSTLY AI prioritizes the foreign key relationship and the issue is handled gracefully.
- MCD-1951 - Resolved an issue when MOSTLY AI writes primary keys in UUID format that are longer than the maximum number of characters allowed by the column data type in the destination database
v107
Jun 21st, 2023
Databricks support
You can now create Databricks connectors and use Databricks catalogs as a data source or destination for your generated synthetic data.
Coherence report for linked tables
The Model QA report and Data QA report now contain a Coherence tab for linked tables (event & time-series data). In the Coherence tab, you can find bivariate plots that show how well the sequence and logic of events is preserved in the synthetic data.
Auto-update of training settings based on selected training goal
When you set the Training goal for a synthetic data job, MOSTLY AI now auto-updates the training settings Maximum training epochs and Training samples to values appropriate for the selected training goal.
Accuracy | Maximum training epochs is set to 100 |

A smarter, faster & more efficient MOSTLY AI
For the past few months, we have been working to make synthetic data work for your business. Here are some of the highlights:
-
We achieved a more than two-fold increase in synthesization speed, significantly reducing the resource footprint of synthetic data in your company.
-
Preparing synthetic data has become much simpler. The engine now determines the best AI model and outlier protection settings for your dataset and use case.
-
Benefit from better resilience for missing files, rows, columns, and so on. Defects in your data sources will no longer cause issues.
Increased speed
Benefit from a smaller synthetic data footprint and shorter time-to-data
-
MOSTLY AI can not only process datasets virtually limitless in size, it can now ingest and encode them faster than before.
-
Overall AI model training speeds halved, and wide tables now benefit from a faster training time for the first epoch.
-
We achieved a ten-fold increase in synthetic data generation performance. What MOSTLY AI used to generate in minutes can now be done in seconds.
Better synthetic data
Privacy-security is now out-of-the-box and takes zero effort to realize
-
MOSTLY AI protects rare categories by replacing them with non-rare categories. Release 2.2 replaces them in a context-aware manner. For instance, if a female data subject has a rare name, it will be replaced with a female non-rare name.
-
Rare category protection can no longer be adjusted or turned off.
-
Extreme values are now protected in all numerical formats, including datetime and ITT.
-
Lists, sequences, and time-series data now benefit from extreme sequence length protection.
-
Improved accuracy of sequence length distributions in the synthetic data, as minimum sequence lengths are now respected.
Simpler preparation
-
Use the batch size AI model training parameters to balance training speed with memory availability. The appropriate learning rate is now calculated in the background.
-
If your synthesization job doesn't run as desired, you can choose a smaller or bigger AI model size to mitigate the issue.
-
The job summary now shows a progress bar for each epoch, giving you an indication of how long AI model training will take.
-
The "generate more data" function for synthesization jobs created with release 2.2 will now work with all upcoming versions of MOSTLY AI.
Manage users and groups
Create groups and let users share assets across them
-
As an admin, you can now create groups and manage group-level access permissions. This makes it easier to manage permissions for multiple users or reassign individual users if they change jobs in the organization.
-
As a user, you can now share synthetic data assets with your group or with other groups.
MySQL Data connector
Use the MySQL family of databases for synthetic data
The MySQL data connector enables synthetic data in the cloud and integrates MOSTLY AI with cloud databases like AWS Aurora, Google Cloud SQL, and many more.
Resolved issues
- MPD-1781 - License issues due to restarted VMs.
- MPD-1439 - The data connector details view doesn't show the database name.
- MCD-952 - The AI server crashes when there's an issue with assigning foreign keys using Smart Select.
- MCD-939 - Generation crashed if the precision is specified for columns with floating point numbers.

Our new Text encoding type allows you to synthesize unstructured natural language. MOSTLY AI 2.1 now covers all tabular data types, from categories to geolocation data and beyond. The world is all yours!
-
Benefit from searchable and interactive charts in the QA report, allowing you to intuitively spot opportunities to further improve synthetic data quality.
Synthetic text
Put unstructured natural language texts to use in your AI/ML applications.
Insurance claim reports, medical diagnoses, and other types of unstructured texts are very rich sources of information, capturing details that aren't present in numbers or other structured forms of data.
Our new Text encoding type allows you to privacy-protect these texts and put them to use in various AI/ML use cases, for example:
- Named-entity recognition
- Sentiment analysis
- Testing—by generating real descriptions
- E-commerce analytics—by synthesizing customers' search keywords
DB2 Data connector
Use DB2 databases for synthetic data
You can now connect MOSTLY AI to the DB2 family of databases. + Use them as a data source or as a destination, and enable synthetic data for mainframe applications.

v2.0
Nov 2nd, 2021
Synthetize your data wherever it is
Mostly AI 2.0 is now capable of synthesizing entire databases!
It connects to your data sources, recognizes its columns and their relationships, and provides you with a synthetic version of your data wherever you need it.
There are no more limits to what you can synthesize. Connect to your databases, buckets, and files without any hurdles.
Be ready for the synthetic data revolution. It’s already here.
New UI
A new customer centric UI
With Mostly AI 2.0 we introduce a new UI!
The new UI has been redesigned with a customer centric approach.
The task of creating a new synthesization job has never been easier.
And it looks cool too!
Multi-table data catalog
Synthesize complex data structures
With Mostly AI 2.0 it is now possible to define multi-table data catalogs!
The complexity of your data source is now represented in the data catalog:
- Support of primary keys,
- Support of foreign keys,
- and Referential integrity.
The platform understands the relationships between all the tables and create a synthesization plan based on these relationships.
The result is synthetic version of your data in its original form!
Parallel computing
Better performance thanks to parallelization
Thanks to a major architectural redesign, the Mostly AI platform now supports parallel computing.
In case of multi-table synthetic generation, the Mostly AI platform will intelligently divide the tasks that can be calculated in parallel in the available VMs.
Data connectors
Create your data source once and re-use it!
You can now define data connectors in the Mostly AI platform!
Data connector can be used as a source of data or as a data destination.
You can fetch data from your production data lake or database and push them wherever you need!
Mock data
A perfect way to test the extremes
Some of the biggest challenges when testing software can be getting the software into some very specific states. You want to test that the new error message works, but this message is only shown when something breaks. You may have no direct control over and you really need to manipulate this data in order to perform your tests.
You can now define Mock Data in the generation process!
Mock data makes it possible to simulate errors and circumstances that would otherwise be very difficult to create in a real world environment.
New QA report
A new and intuitive QA report
The new QA Report is available directly in the UI. You can explore the results of your generation job and see if there are privacy or accuracy warnings!
