Microsoft Foundry の評価

FoundryEvals は、Agent Framework の評価 API を Microsoft Foundry のマネージド評価サービスに接続します。 品質、安全性、ツール利用、エージェントの動作、ルーブリックの評価機能を提供し、保存済みレポートは Foundry ポータルで利用できます。

EvalItem、ローカル チェック、カスタム エバリュエーター、会話分割戦略については、「エージェントの評価」を参照してください。

前提条件

• Microsoft Foundry プロジェクトとモデルの配置。
• プロジェクトを対象とした Foundry エンドポイント。
• 評価を送信し、レポートを読み取るアクセス許可。

品質ゲート

結果が実行全体で比較可能である必要がある場合に、データセット、モデル デプロイ、エバリュエーター バージョン、ルーブリック バージョンをピン留めします。 必要なメトリクスが悪化した場合に CI を失敗させるには、結果アサーションヘルパーを使用します。
