**Planview 如何利用 Amazon Bedrock 打造可擴展的 AI 助理進行項目管理**

由 Sunil Ramachandra、Benedict Augustine 和 Lee Rehwinkel 撰寫

現今企業在管理複雜的項目和計劃時面臨不少挑戰,包括從大量數據中提取有價值的見解以及作出及時決策。這些問題經常導致項目經理和高層管理人員的生產力瓶頸,阻礙了有效推動組織成功的能力。

Planview 作為連接工作管理解決方案的領先供應商,於 2023 年開展了一項雄心勃勃的計劃,旨在革新全球 300 萬用戶與其項目管理應用程式的互動方式。為實現這一願景,Planview 開發了一款名為 Planview Copilot 的 AI 助理,採用由 Amazon Bedrock 支援的多代理系統。

**開發多代理系統的挑戰:**

– 將任務可靠地路由到適當的 AI 代理
– 從各種來源和格式訪問數據
– 與多個應用程序 API 互動
– 允許不同產品團隊自助創建新的 AI 技能

為克服這些挑戰,Planview 使用 Amazon Bedrock 開發了一個多代理架構。Amazon Bedrock 是一個完全託管的服務,提供對 Amazon 和其他領先 AI 初創公司的基礎模型(FM)的 API 訪問,這使得開發人員能夠選擇最適合其用例的 FM。這種方法在架構和組織上都是可擴展的,使 Planview 能夠快速開發和部署新 AI 技能,以滿足客戶不斷變化的需求。

**解決方案概述**

Planview 的多代理架構由多個生成式 AI 組件協作組成一個單一系統。其核心是一個負責將問題路由到各個代理,收集學到的信息,並向用戶提供綜合回應的協調器。協調器由中央開發團隊管理,代理則由每個應用程序團隊管理。

協調器由兩個主要組件組成,稱為路由器和應答器,由大型語言模型(LLM)提供支持。路由器利用 AI 將用戶問題智能地路由到具有專業能力的應用程序代理。代理可以分為三種類型:

– 幫助代理:使用檢索增強生成(RAG)提供應用程序幫助
– 數據代理:動態訪問和分析客戶數據
– 操作代理:代表用戶在應用程序中執行操作

在代理處理問題並提供回應後,應答器同樣由 LLM 提供支持,綜合所學信息並為用戶制定連貫的回應。這種架構允許集中協調器與專業代理之間的無縫協作,為用戶提供準確和全面的答案。

**技術概覽**

Planview 使用關鍵的 AWS 服務構建其多代理架構。由 Amazon Elastic Kubernetes Service(Amazon EKS)提供支持的中央 Copilot 服務負責協調各個服務之間的活動。其責任包括:

– 使用 Amazon Relational Database Service(Amazon RDS)管理用戶會話聊天歷史
– 協調路由器、應用程序代理和應答器之間的流量
– 處理日誌記錄、監控和收集用戶提交的反饋

路由器和應答器是與 Amazon Bedrock 互動的 AWS Lambda 函數。路由器考慮用戶的問題和中央 Copilot 服務的聊天歷史,而應答器則考慮用戶的問題、聊天歷史和每個代理的回應。

應用程序團隊使用與 Amazon Bedrock 互動的 Lambda 函數管理其代理。為了提高可見性、評估和監控,Planview 採用了集中提示庫服務來存儲 LLM 提示。

代理可以根據用例和數據可用性使用各種方法與應用程序進行交互:

– 現有應用程序 API:代理可以通過其現有的 API 端點與應用程序通信
– Amazon Athena 或傳統 SQL 數據存儲:代理可以從 Amazon Athena 或其他基於 SQL 的數據存儲檢索數據以提供相關信息
– Amazon Neptune 用於圖數據:代理可以訪問存儲在 Amazon Neptune 中的圖數據以支持複雜的依賴性分析
– Amazon OpenSearch Service 用於文檔 RAG:代理可以使用 Amazon OpenSearch Service 對文檔執行 RAG

**模型評估與選擇**

評估和監控生成式 AI 模型性能在任何 AI 系統中都是至關重要的。Planview 的多代理架構允許在各組件層面進行評估,儘管系統複雜,但仍能提供全面的質量控制。Planview 對組件進行三個層次的評估:

– 提示:評估 LLM 提示的有效性和準確性
– AI 代理:評估完整提示鏈以保持最佳任務處理和回應相關性
– AI 系統:測試面向用戶的互動以驗證所有組件的無縫集成

**結果與影響**

在過去一年中,Planview Copilot 的性能通過實施多代理架構、開發強大的評估框架以及採用 Amazon Bedrock 提供的最新 FMs 得到了顯著改善。Planview 在 2023 年中期開發的第一代 Planview Copilot 與最新版本之間的結果包括:

– 準確性:人類評估的準確性從 50% 的答案接受率提高到現在超過 95%
– 回應時間:平均回應時間從超過 1 分鐘減少到 20 秒
– 負載測試:AI 助理成功通過負載測試,同時提交 1,000 個問題而未對回應時間或質量產生顯著影響
– 成本效益:每次客戶互動的成本已降至初始費用的十分之一
– 市場推進時間:新代理的開發和部署時間從幾個月縮短到幾周

**編者評論**

Planview 的案例展示了如何利用先進的 AI 技術來提升企業運營效率。透過集成 Amazon Bedrock,Planview 能夠迅速適應不斷變化的市場需求,並提供更為精準的用戶體驗。然而,這也提醒我們,技術的應用不僅僅是提升效率,還需考慮到人類監控和評估的必要性,以確保 AI 系統的公平性和可靠性。在未來,如何平衡技術創新與人類價值將成為企業的重要課題。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony.
