gemma-4-E4B-it-assistant_gguf

Gemma4は小さいモデルに先行させる事で推論を高速化するMTP(Multi-Token Prediction)という仕組みがあります。
このモデルはdahara1/gemma-4-E4B-it-UD-japanese-imatrixをMTPで動かすための小モデルです。

Gemma4 has a mechanism called MTP (Multi-Token Prediction) that speeds up inference by running a smaller model before the main model.
This model is a small model for running dahara1/gemma-4-E4B-it-UD-japanese-imatrix using MTP.

E4Bでは現在、明示的に--flash-attn offにする必要があります。
詳細はissues/24400をご覧ください

In E4B, you now need to explicitly set --flash-attn off.
See issues/24400 for details.
