 * `1/8/2025`: **Text generation with foundation model APIs** based on the paper [`Differentially Private Synthetic Data via Foundation Model APIs 2: Text`](https://arxiv.org/abs/2403.01749) has been integrated into the library! If you want to reproduce the results in the [paper](https://arxiv.org/abs/2403.01749), please refer to [our original codebase](https://github.com/AI-secure/aug-pe).
 * `11/21/2024`: The refactored codebase for **image generation with foundation model APIs** based on the paper [`Differentially Private Synthetic Data via Foundation Model APIs 1: Images`](https://arxiv.org/abs/2305.15560) has been released! It is completely refactored to be more modular and easier to use and extend. The code originally published with the [paper](https://arxiv.org/abs/2305.15560) has been moved to the [deprecated](https://github.com/microsoft/DPSDA/tree/deprecated) branch in this repository, which is no longer maintained.
