Only if decompressor and image are transmitted over the same channel at the same time, and you only have a small number of images. When compressing images for the web I don't care if a webp decompressor is smaller than a jpg or png decompressor, because the recipient already has all of those.

Of course stable diffusion's 4GB is much more extreme than Brotli's 120kb dictionary size, and would bloat a Browser's install size substantially. But for someone like Instagram or a Camera maker it could still make sense. Or imagine phones having the dictionary shipped in the OS to save just a couple kB on bad data connections.

Even if dictionaries were shipped, the biggest difficulty would be performance and resources. Most of these models require beefy compute and a large amount of VRAM that isn't likely to ever exist on end devices.

Unless that can be resolved it just doesn't make sense to use it as a (de)compressor.
