[ DevOps in AI Agent ] Google ADK AI Agent Evaluation 概念介紹 (1/2)> The English version is below.> 此系列因文章較長,我將會將文章拆成「功能介紹篇」與「技術實作篇」,再請大家閱讀並且按鼓勵給予支持。當今天將 AI Agent 開發完成後,依照軟體開發的流程,單元測試(Unit Test)與整合測試(Integration Test)扮演著確保系統穩定與可靠的關鍵角色。然而,大型語言模型 AI Agent 的出現,帶來了全新的挑戰。由於模型本身具備機率性,相同輸入在不同情境下,從使用第三方工具到回覆結果,皆有可能產生略有差異的輸出。因此,對這類系統而言,「通過/失敗」這類二元判斷並不足以反映 AI Agent 的整體表現。本文將深入介紹 Google ADK AI Agent 開源工具中,是如何設計 Evaluation 這項功能,以及說明它如何協助開發者在機率性與可變性的環境中,依然維持對 AI Agent 的品質掌控與開發信心。Link: https://lnkd.in/gKk6QZFg===[ DevOps in AI Agent ] Introduction to Google ADK AI Agent Evaluation Concept (1/2)> Due to the length of this series, I’ve divided the article into two parts — “Feature Overview” and “Technical Implementation.” Please take some time to read them and show your support with a clap.Once an AI Agent has been developed, following standard software development practices, **unit testing** and **integration testing** play a critical role in ensuring the system’s stability and reliability.However, the emergence of **large language model (LLM)–based AI Agents** introduces new challenges. Because these models are inherently probabilistic, the same input under different conditions — from invoking third-party tools to generating responses — may produce slightly different outputs. As a result, binary judgments like “pass” or “fail” are insufficient to capture the full performance picture of an AI Agent.This article explores how the **Evaluation** feature is designed within **Google ADK’s open-source AI Agent toolkit**, and explains how it helps developers maintain quality control and confidence in their AI Agent’s performance, even within an environment of variability and probabilistic behavior.Link: https://lnkd.in/gKk6QZFg
