Model Types

Gretel's models can help you transform and synthesize your sensitive data to generate provably-private versions.

Synthetics

Gretel offers the following synthetics models:

1. Tabular Fine-Tuning - Gretel’s flagship LLM-based model for generating privacy-preserving, real-world quality synthetic data across numeric, categorical, text, JSON, and event-based tabular data with up to ~50 columns.

   1. Data types: Numeric, categorical, text, JSON, event-based

   2. Differential privacy: Optional

   3. Formerly known as: Navigator Fine Tuning

2. Text Fine-Tuning - Gretel’s model for generating privacy-preserving synthetic text using your choice of top performing open-source models.

   1. Data types: Text

   2. Differential privacy: Optional

   3. Formerly known as: Gretel GPT

3. Tabular GAN - Gretel’s model for quickly generating synthetic numeric and categorical data for high-dimensional datasets (>50 columns) while preserving relationships between numeric and categorical columns.

   1. Data types: Numeric, categorical

   2. Differential privacy: NOT supported

   3. Formerly known as: ACTGAN

4. Tabular DP - Gretel’s model for generating differentially-private data with very low epsilon values (maximum privacy). It is best for basic analytics use cases (e.g. pairwise modeling), and runs on CPU. If your use case is training an ML model to learn deep insights in the data, Tabular Fine-Tuning is your best option.

   1. Data types: Numeric, categorical

   2. Differential privacy: Required; you cannot run without differential privacy

Transform

Gretel’s Transform model combines data classification with data transformation to easily detect and anonymize or mutate sensitive data. Use this data classification to detect a variety of Supported Entities such as PII, in both structured and unstructured text.

We generally recommend combining Gretel Transform with Gretel Synthetics using workflows to redact or replace sensitive data before training a synthetics model.
