レスポンスモデルがあると、FastAPI は中間ステップ（他の場合に行われる `jsonable_encoder` による変換など）を介さずに、Pydantic を使ってデータをJSONにシリアライズします。

内部的には、Pydantic はJSONシリアライズに `orjson` と同じRust由来の仕組みを用いているため、レスポンスモデルを使うだけで最良のパフォーマンスが得られます。

## デフォルトレスポンスクラス { #default-response-class }

**FastAPI** クラスのインスタンスや `APIRouter` を作成する際に、デフォルトで使用するレスポンスクラスを指定できます。

これを定義するパラメータは `default_response_class` です。
