| We still use GANs a lot. They're way faster than diffusion

| series cards. They are just naturally computationally cheaper,

| another and few revisit. But when revisits happen, they tend to
| be competitive. See ResNets Strike Back for even CNNs vs ViTs.
| But there's more nuance here).

| There is a reason your upscaling model is a GAN. Sure, diffusion
| can do this too. But why is everyone using ESRGAN? There's a
| reason for this.
|
| Also, I think it is important to remember that GAN is really
| about a technique, not about generating images. You have a model
| generating things, and another model telling you something is a
| good output or not. LLM people... does this sound familiar?
|
| To the author: I think it is worth pointing to Tero Karras's
| Nivida page. This group defined the status quo of GANs. You'll
| find that the vast majority of GAN research built off of their
| research. As quite a large portion of are literal forks. Though a
| fair amount of this is due to the great optimization they did,
| with custom cuda kernels (this is not the limiting compute factor
| in diffusion). https://research.nvidia.com/person/tero-karras
