Evaluation and Benchmarks
Frechet Inception Distance - metric measuring similarity between generated and real image distributions using feature statistics.
Stable Diffusion 3 achieves FID of 22.5 on COCO validation vs FID of 45.2 for Stable Diffusion 1.5 - used to compare generative image model quality and track improvement across versions.
Adobe Firefly uses FID alongside human preference studies to validate image quality before production deployment - FID alone can miss perceptual quality issues, so both metrics are used together.
BigGAN (DeepMind) achieved FID of 7.4 on ImageNet in 2018, establishing a new SOTA - the score is used in academic papers to claim superiority over prior generative models.
