画像タグ付け（Tagger）のモデルについて
初めに
２０２６年９月時点の情報です。
WD14系
WD EVA02-Large Tagger
タグ数：10,861（一般：8,106、キャラクター：2,751、レーティング：4）
カテゴリ：一般（General）、キャラクター、レーティング
所感：WD14系は安定していて使いやすい。タグは各モデルで共通だがモデルごとにTag判定のアーキテクチャが違う。
WD ViT-Large Tagger
WD SwinV2 Tagger
WD ConvNext Tagger
WD ViT Tagger
Pixai系
Pixai tagger v09
タグ数：13,641（一般：9,741、キャラクター：3,720）
カテゴリ：一般（General）、キャラクター
所感：公式にある通り、キャラクターの閾値は高め（0.75）にしないとかなり誤検知がある。複数キャラクターで学習しているためか、同一作品や、ペア・グループになっているキャラクターも同時に検知されがちになる。
ML Danbooru
ML-Danbooru m36
タグ数：12,547
カテゴリ：一般
所感：標準の閾値は0.7となっているが、閾値を下げても誤判定は少ない。他と違って、一般タグにはカテゴリが混ざっていないため、キャラクターの判定はできないが個人的にはメリットの方が大きい（キャラクターは最新のに対応していなかったり誤判定も多いので手動でタグをつけたほうが安定する）。服装判定の〇〇(Cosplay)や作品の制服（〇〇 uniform）などは判定される。
その他
Camie tagger v2
タグ数：70527
カテゴリ：一般（General）、キャラクター、年（Year）、アーティスト、版権（Copyright）、メタ（Meta）、レーティング
所感：カテゴリが多い分タグ数も多いが細かい分誤判定も多く感じる。一般タグ以外は特に誤判定が多いように思える。特に年（Year）は年代ではなく１年単位なので正しい判定はほぼできない気がする。
Oppai Oracle v1.1
タグ数：19,294
カテゴリ：一般（General）
所感：閾値は高め（0.7前後）。カテゴリ分けはされていないが、キャラクターや版権・作品、絵師、メタなどのタグも含まれる。特定のカテゴリだけを除外できないので誤判定がそのまま出力に含まれてしまうので使いづらい部分もある。V2を作成予定のようなのでV2に期待。
CL tagger v1.02
タグ数：42,163（一般：22,367、キャラクター：16,210、版権：3,329、メタ：224、モデル：25、レーティング：4、クオリティ：4）
カテゴリ：一般（General）、キャラクター、版権（Copyright）、メタ（Meta）、モデル（Stable Diffution）、レーティング、クオリティ
所感：タグは多いが学習素材かタグ付けに問題があるのか誤判定も多い。Taggerにとって色は難しいが特に誤判定が多いように思われる。
Z3D E621 Convnext
タグ数：9,525（一般：6,249、アーティスト：924、キャラクター：541、版権：516、メタ：223、種（生物）：1,060、設定（lore）：12）
カテゴリ：一般（General）、キャラクター、版権（Copyright）、メタ（Meta）、種（生物）、設定
所感：E621という、擬人化（ケモナー）向けサイトをもとにしただけあってタグのカテゴリ、内容ともに独特。Danbooruとも違うので個人的には使いづらい。
Taggerine
タグ数：74,625
カテゴリ：一般（General）、アーティスト、キャラクター、版権（Copyright）、メタ（Meta）、種（生物）、設定（lore）、カラリスト（Colorist）
所感：E621+Danbooruでタグ付けされ、DINOv3 ViT-H/16+で学習したモデル。誤検知もそこそこあるので高めの閾値が望ましい。
各モデルごとの出力例
モデルごとに閾値の意味も値も変わるのでタグの多い少ないは比較対象になりません。サンプル画像はAI生成でわざと色々な要素を詰め込んでいます。
