GigaGAN: Scaling up GANs for Text-to-Image Synthesis

Scaling up GANs for Text-to-Image Synthesis

present our 1B-parameter GigaGAN, achieving lower FID than Stable Diffusion v1.5, DALL·E 2, and Parti-750M. It generates 512px outputs at 0.13s, orders of magnitude faster than diffusion and autoregressive …
