Mixtral-8x22Bをllama.cppで実行する #LLM

Hugging Faceのトレンドに上がっていた、Mixtral-8x22Bを試してみました。

Mixtral-8x22Bとは

The Mixtral-8x22B Large Language Model (LLM) is a pretrained generative Sparse Mixture of Experts.

としか書かれていないので、謎が多いですね。

実行環境

実行環境としては、llama.cppを使います。
PCのスペック：

CPU: E5-2680v4
Memory: 64GB
SSD: WD_BLACK_SN770
GPU: GeForce RTX 4060Ti 16GB
OS: Windows 10 + WSL2

最初はHDDにモデルファイルを置いていたのですが、実行に1日以上掛かってしまいました。SSDだと1時間掛かりません。、

llama.cppのビルド

最新のllama.cppをダウンロードしてビルドしてください。バイナリで出回っているものでは動かないようです。

git clone https://github.com/ggerganov/llama.cpp.git
cd llama.cpp
make LLAMA_CUDA=1

自分の環境では、CUDAでオフロードできるので、CUDAを使う設定でビルドします。
ただ、実行中はあまり使っていないようです。

モデルをダウンロード

MaziyarPanahi/Mixtral-8x22B-v0.1-GGUF　から、2-bitのモデルをダウンロードする。

Mixtral-8x22B-v0.1.Q2_K-0000[12345]-of-00005.gguf

の５つのファイルをダウンロードしました。トータルで約50GBになります。

実行

~/llama.cpp/main -m Mixtral-8x22B-v0.1.Q2_K-00001-of-00005.gguf -p "Building a website can be done in 10 simple steps:\nStep 1:" -n 1024 -e

モデルファイルは５つとも全て同じディレクトリにある必要があります。今回はカレントディレクトリに置いて実行しています。

考察

トータルの実行時間は、1953秒でとなりました。

2bitsのモデルですが、まあ、普通に回答していますね。
ちょっと分からないのは、二重に回答していて、それぞれが全然対応取れてないということでしょうか。

日本語で質問してみましたが、回答は英語となります。日本語で回答してという指示に対しては、最初は日本語で出てきましたが、少しすると英語に変わってしまいます。日本語は苦手のように思いました。

以上、とりあえずのお試しです。規模が大きいので、4bitsや8bitsを試すのは難しそうです。
