C言語 + テスト

インストール

LLM

Qwen3 Swallowのラインナップは、3つの軸で整理すると分かりやすくなります。

1. モデルサイズ（ベースモデル）

8B — Qwen3-8B ベース。単一GPUで動く軽量モデル

30B-A3B — Mixture of Experts (MoE)。総パラメータ30Bだが推論時にアクティブなのは3Bだけなので、サイズの割に軽い

32B — Qwen3-32B ベース。最も高性能だがVRAMも最大

2. 学習段階（縦の進行度）

下から上に向かって学習が進んでいます。

CPT (Continual Pre-Training) — 日本語データで追加事前学習しただけ。指示に従う能力はまだ弱い。研究・実験向け

SFT (Supervised Fine-Tuning) — CPTの上に指示追従の教師あり学習を実施。会話はできるが最適化が甘い

RL (Reinforcement Learning) — SFTの上にさらに強化学習（GRPO等）を実施。これが完成版

つまり CPT → SFT → RL の順に仕上がっていて、普通に使うならRL版を選べばOKです。CPTとSFTは「試験版」と明記されている通り、学習プロセスの途中成果物です。

3. 量子化（推論コスト削減）

完全版（量子化なし） — フル精度。品質最高だがVRAM大

AWQ-INT4 — 4bit量子化の一方式。速度寄りの最適化

GPTQ-INT4 — 4bit量子化のもう一方式。互換性が広い

品質はほぼ同等で、使うフレームワーク（vLLM → AWQ、text-generation-webui → GPTQ など）に合わせて選ぶのが一般的です。

table:実用的な選び方

目的 おすすめ

手元のGPUで手軽に試したい 8B RL v0.2 (AWQ or GPTQ)

コスパ重視で賢いモデルが欲しい 30B-A3B RL v0.2（MoEで軽い）

最高性能 32B RL v0.2

学習パイプラインの研究 CPT/SFT版を比較

Q. vLLM/AWQ/text-generation-webui/GPTQ とは何か

推論フレームワーク

LLMをローカルで動かすためのソフトウェアです。

量子化手法

モデルの重みを低ビット（例: FP16→INT4）に圧縮して、VRAM使用量を大幅に減らす技術です。どちらもINT4（4ビット）にする点は同じですが、やり方が違います。

まとめると

table:まとめ

用語 役割 一言で

vLLM 推論エンジン 高速サーバー向け

text-generation-webui 推論UI 個人のローカル利用向け

AWQ 量子化手法 vLLMと好相性

GPTQ 量子化手法 対応ツールが広い

フレームワークと量子化手法の組み合わせで「どの環境でどう軽くするか」が決まる、という関係です。
