Unfortunately there's no gguf quants of the assistant model yet:

I think MTP Gemma4 support is still WIP https://github.com/ggml-org/llama.cpp/pull/23398 ?
This has been my impression.
The underlying LiteRT-LM framework used in the edge gallery does support the MTP drafters for the smaller models, but according to:
https://developers.google.com/edge/litert-lm/models/gemma-4
> Note: LiteRT-LM supports E2B and E4B models today, with support for larger models coming soon.
So even Google aren't shipping MTP support for the 26B and 31B models yet.
