About

What is micro_diffusion?

micro_diffusion is an open-source repository from Sony Research that provides a minimalistic implementation for training large-scale diffusion models from scratch with an extremely low budget. Utilizing only 37 million publicly available real and synthetic images, it can train a 1.16 billion parameter sparse transformer for approximately $1,890, achieving a strong FID score on the COCO dataset. The repository includes training code, dataset code, and pre-trained model checkpoints for off-the-shelf generation. It supports progressive training from low to high resolution and incorporates patch masking for performance optimization and reduced training time.

Best used for

Ideal for AI researchers and developers who need to train large-scale diffusion models efficiently and cost-effectively, reproduce published research, and experiment with optimized training techniques. Especially valuable for those with limited computational budgets seeking high-performance models.

FAQs

What is the estimated cost to train a model using micro_diffusion?

The repository highlights that a 1.16 billion parameter sparse transformer can be trained for approximately $1,890, achieving an FID of 12.7 on the COCO dataset. This cost is based on using 37 million publicly available real and synthetic images.

What kind of hardware is recommended for training with micro_diffusion?

The documentation specifies that the estimated training time for the end-to-end model on an 8xH100 machine is 2.6 days. This suggests that access to powerful GPUs is beneficial for efficient training.

Does micro_diffusion provide pre-trained models?

Yes, the repository releases four pre-trained models, which are available for download. These checkpoints allow users to perform off-the-shelf generation without needing to train models from scratch.
