Gemma 4 12B

Gemma 4 12B

Gemma 4 12Bの概要

Gemma 4 E4Bと26B MoEの中間に位置するモデル

音声入力をネイティブでサポートする初のミドルサイズモデル

特徴的な統合アーキテクチャ

画像・音声専用の独立したエンコーダーを排除

画像は軽量な埋め込みモジュールで処理

音声信号は生のデータを直接テキストトークンと同じ次元空間に投影

性能と効率性

26B MoEに近い推論能力を実現

16GBのVRAMまたはユニファイドメモリで動作可能

推論レイテンシ低減のためマルチトークン予測（MTP）ドラフターを搭載

beta runtimeにアップデートして成功

派生GGUFを使うとメッセージのやりとりでエラーが起きる

lmstudio-community製に搭載されているプロンプトテンプレートを移植すると使える
