Tutorial: Pixart-α diffusion transformer for text-to-image generation at 10.8% of Stable Diffusion training cost
Training state-of-the-art text-to-image models like Stable Diffusion v1.5 demands enormous computational resources — 6K A100 GPU days costing approximately $320,000 — along with significant CO2 emissions, creating serious barriers for researchers and entrepreneurs.

Outcome
Pixart-α achieves competitive image quality with state-of-the-art generators at only 10.8% of the training time of Stable Diffusion v1.5, generating high-resolution images up to 1024 pixels with stronger text-image alignment than Stable Diffusion XL.
