單圖生成逼真數位化身：Lemon Slice獲1050萬美元融資，挑戰AI「恐怖谷」
AI新創Lemon Slice發表Lemon Slice-2模型，僅需單張圖片即可生成逼真互動的數位化身，並獲1050萬美元種子輪融資，旨在解決現有AI化身的「恐怖谷」問題。
數位化身生成新創公司於12月23日宣布，已完成的種子輪融資，並發表其最新的模型「」。該模型僅需一張圖像，即可生成可即時互動的影片化身，旨在為目前以文字為主的聊天機器人增添生動的視覺層次。
技術核心：告別僵硬化身
由Lina Colucci等人於2024年創立的，其核心技術為一個參數的。據公司稱，該模型能以單一實現的即時影像串流，可應用於客服、教育輔導甚至心理健康支援等多元場景。
共同創辦人Colucci直言：「我至今所見的現有化身解決方案，都為產品帶來了負面價值。它們既詭異又僵硬。」她認為，正是品質不足阻礙了數位化身的普及，而的目標正是要跨越這道「恐怖谷」，提供令人感到自在的互動體驗。
市場布局與投資者信心
本輪融資由及領投，參與者包括Dropbox技術長、Twitch執行長等科技界巨擘。企業客戶可透過或一行程式碼（）即可嵌入的工具，將此技術整合至網站。化身的聲音生成則採用了的技術。
Y Combinator的合夥人Jared Friedman認為，採用的基礎機器學習方法，是唯一有潛力克服恐怖谷效應的公司。他指出：「這是一個通用的端到端模型，其逼真程度沒有天花板，而其他競爭者則止步於擬真之下。」
人機互動正從文字走向多模態。Lemon Slice的出現，標誌著通用影片生成模型正從技術展示走向商業應用，其核心戰場正是跨越「恐怖谷」。未來，AI不僅要能言善道，更需要一張自然、可信的「臉」，這將是決定下一代數位服務體驗的關鍵。
