面向生產級 AI 的代理可觀測性、評估與持續改進平台
基於 OpenTelemetry 之上的 OpenInference 規範，蒐集代理與 LLM 呼叫的 span、trace 與工作階段，埋點可跨工具重複使用。
在 span、trace 與工作階段三個層級執行評估，對大量生產資料衡量檢索品質、工具呼叫與最終回覆的優劣。
內建於產品中的代理，可檢查链路、推斷根因，並給出供工程師上線前審閱的修復建議。
當需要讓軌跡資料留在自有基礎設施內時，可自行部署這套領先的開源追蹤與評估工具。

專項更強在互聯環境中追蹤、評估並交付 AI 模型與代理。
免費 / 開源提供具彈性的開源替代方案，適用於自訂資料標註與真人迴路（Human-in-the-loop）標註管線。
專項更強Provides LLM evaluation and testing workflows, but lacks Scale's massive human-in-the-loop data labeling services.
透過 DeepEval 提供全面的 LLM 評估與單元測試，但缺乏 Arize 深度生產監控基礎設施。
提供企業級多模態標註與資料管理工具，但較不強調託管式的標註人力。
專項更強打造、模擬、評估並監控能自我改進的 AI 代理
高度專注於提示詞管理與版本控制，而 Arize 則優先考慮端到端追蹤與機器學習可觀測性。
