Diffusion Model vs GAN vs VAE vs Flow Matching: A Production Deployment Guide
Most generative AI architecture guides read like a competition. Diffusion wins on quality. GANs are obsolete. Flow matching is the future. These rankings are easy to write and nearly useless for engineering decisions. GANs, VAEs, diffusion models, and flow matching were each built for a different job. The right choice depends on the constraints of the system being built. That
