    --- GA: UA-34467841-15 --- # Serverless, WebAssembly (Wasm) - 莊翔任(Sean) ###### tags: `HelloWorld2025` `HWDC2025` `2025` `A 會議室` `AI 如何改變產品規劃與需求定義` <blockquote> 在 AI 日益強調即時性、隱私與低功耗的時代,Edge AI 成為許多企業與開發者的重要佈局。然而模型部署仍面臨平台相容性、執行效能與資源限制等挑戰。本演講將分享如何透過 WebAssembly(Wasm)技術,實現高可攜、可離線運行的 AI 推論模組,並介紹在 MediaPipe + Gemini Nano + WebAssembly 架構下的實測經驗。 本次深入探討 AI 模型如何轉換為適合瀏覽器的輕量型格式,結合向量資料庫與 SLM(Small Language Models)進行本地推論。歡迎對 AI 輕量部署、Web 技術與 Edge Intelligence 有興趣的開發者一同交流與討論。 聽眾收穫: 了解 WebAssembly 在 AI 模型本地推論上的應用場景與優勢 如何將 LLM/SLM 模型轉換並部署於瀏覽器與邊緣裝置 實際掌握 MediaPipe + Gemini Nano + Wasm 的整合技巧與潛在限制 掌握從雲端架構遷移至邊緣部署的技術挑戰與解決策略 </blockquote> {%hackmd @HWDC/announcement-2025 %} ## 會議資訊 **時間:** 10:05 ~ 10:35 **地點:** A 會議室 **日期:** 2025年10月15日 **語言:** 中文 **難度:** 中階 **相關連結:** - [Hello World Dev Conference 2025 官方網站](https://hwdc.ithome.com.tw/2025) [target=_blank] - [Hello World 2025 議程表](https://hwdc.ithome.com.tw/2025/agenda) [target=_blank] ## 筆記區 ### Edge AI 資料不必上傳雲端 -> 提升隱私與安全性 可離線運作 -> 提升穩定度以及可靠性 #### 應用 - 手機影像辨識 - 智慧監控 ### WebAssembly (wasm) 前端加速: 影像處理、影片編碼、3D 渲染、遊戲引擎 Edge AI 推論 跨平台運算: nodejs demo Iot Example: Google Earth, Figma, Photoshop (on web) ### Edge AI & wasm ### Small Language Model (SLM) 參數較少(1億-100億) 推理速度快 延遲低 較易調整模型 Google MediaPipe - cross platform AI framework ### Edge AI Chatbot ### Integration Question -> Edge AI -- if not good --> (Server) RAG -> LLM -> Answer -- if good --> Answer ### AI memo 根據您的筆記內容,這是一個關於邊緣AI(Edge AI)與WebAssembly技術結合的完整技術分享。筆記涵蓋了以下主要內容: **WebAssembly在AI應用中的優勢:** - 提供接近原生的執行效能,適合處理AI推理的低延遲需求 - 在沙盒模式下運行,確保隱私和安全性 - 支援跨平台部署,包括瀏覽器端和IoT設備端 - 可以調用WebGL和設備CPU資源進行高效運算 **小語言模型(輕量化AI模型)的特點:** - 參數量在1億到10億之間,相比大型模型(100億以上參數)更輕量 - 運算需求低,不需要昂貴的GPU硬體 - 部署成本低,適合中小企業使用 - 主流模型包括Phi系列、Llama3 8B系列等 **實作架構與測試結果:** - 使用Google MediaPipe框架進行開發 - 建立了類似ChatGPT的Web應用,整合多個AI模型(Gemma2B、Phi2等)進行比較測試 - 本地端模型能力雖不如遠端API,但在特定場景下仍可提供基本回答 - 結合RAG技術處理內部文件,建立多層次的AI問答系統 **實際應用場景:** - 在專案中將複雜的決策邏輯運算轉移到WebAssembly執行 - 使用微前端架構分離主線程與計算密集型任務 - 預先處理功能避免直接調用伺服器端資源 整體而言,這個技術方案展示了如何在瀏覽器端實現AI功能,兼顧效能、安全性和成本效益。 ## 討論區 > 歡迎在此進行討論與 Q&A ## 相關資源 - 投影片連結:(待講者提供) - 相關文件:(待更新)
