# TiM-Toy-T2I-Dataset

This repository contains the toy dataset for text-to-image (T2I) generation used in the paper [Transition Models: Rethinking the Generative Learning Objective](https://huggingface.co/papers/2509.04394).

Transition Models (TiM) introduce an exact, continuous-time dynamics equation that analytically defines state transitions across any finite time interval. This leads to a novel generative paradigm, TiM, which adapts to arbitrary-step transitions, seamlessly traversing the generative trajectory from single leaps to fine-grained refinement with more steps. This specific dataset serves as a toy dataset for training and experimentation with TiM for text-to-image generation.

Code: [https://github.com/WZDTHU/TiM](https://github.com/WZDTHU/TiM)

## Sample Usage

To download this toy text-to-image dataset for training TiM models, you can follow the instructions from the official GitHub repository under the "Dataset Setup" section:

```bash
bash tools/download_toy_t2i_dataset.sh
```

For more details on setting up the environment, downloading models, and other training/sampling scripts, please refer to the [official GitHub repository](https://github.com/WZDTHU/TiM).
