The big story here is the encoder-free part, which I still don't fully understand.

That's technically encoding, just without using a dedicated model for it like SigLIP? The Developer's Guide elaborates, it's still a 35M layer which I am curious is robust enough. https://developers.googleblog.com/gemma-4-12b-the-developer-...

I am assuming that involves quantization, which due to the quality loss makes that statement somewhat misleading IMO.
