Gemma 3 compatibility

[gottlike]

Was happy to read about ART and excited to use it, but Gemma 3 is unfortunately the only model I want to train, because of its superior multilingual capabilities.

So naturally I was a bit bummed reading that the only model not supported is Gemma 3 🙈. Do you have any further information regarding this? What doesn't work exactly? Is anyone working on a fix?
