Patronus AI 推出革命性「生成模擬器」,徹底改變 AI 代理學習複雜任務方式

由 Lightspeed Venture Partners 和 Datadog 等投資者注資 2,000 萬美元支持的人工智能評估初創公司 Patronus AI,於本周二發佈了一種全新訓練架構,聲稱這將帶來 AI 代理學習複雜任務的根本變革。

這項被稱為「生成模擬器」(Generative Simulators)的技術,能夠創建自適應模擬環境,實時不斷生成新的挑戰、動態更新規則,並評估代理的學習表現。這種方法突破了業界長期以來依賴的靜態基準測試,因為這些傳統測試無法真實反映 AI 在實際應用中的表現。

Patronus AI 執行長兼共同創辦人 Anand Kannappan 在接受專訪時表示:「傳統基準測試只測量單一能力,卻忽略了工作中常見的中斷、情境切換和多層決策。想要讓 AI 代理達到人類水平,必須讓它們透過動態經驗和持續反饋學習。」

靜態基準測試失靈,生成模擬器提供新方向

Patronus AI 指出,業界現有的評估方式如同標準化考試,只在固定時間點測量特定能力,難以捕捉真實工作中複雜且不可預測的情況。新架構則顛覆這種模式,系統會即時生成任務、環境條件及監督流程,並根據代理行為動態調整。

共同創辦人兼技術長 Rebecca Qian 解釋:「過去一年,我們看到業界從靜態基準轉向更具互動性的學習環境。這受益於模型開發者在強化學習、後訓練與持續學習方面的創新,訓練和評估的界線正在模糊,基準測試已變成動態環境。」

此技術基於強化學習(Reinforcement Learning,RL),讓 AI 透過試錯獲得獎勵或懲罰,進而學習做出最佳決策。雖然 RL 有助提升代理能力,但一般需大量代碼重寫,阻礙普及。Patronus AI 則推出「開放式遞歸自我改進」(Open Recursive Self-Improvement,ORSI)概念,讓代理無需重訓即可持續透過互動和反饋提升自己,成為持續學習的關鍵基礎設施。

「黃金區」課程調整器:自適應訓練找到最佳難度

生成模擬器核心在於「課程調整器」(curriculum adjuster),它會分析代理行為,動態調整訓練場景的難度和性質,靈感來自優秀教師會根據學生表現調整教學內容。

Qian 形容:「這就像師生互動,我們訓練模型的同時,教授會不斷調整課程。」

Kannappan 指出,關鍵在於找到訓練資料的「黃金區」,避免太簡單或太難,確保模型真正能夠學習。初步結果顯示,在 Patronus AI 環境中訓練,代理在軟件工程、客服及財務分析等實際任務的完成率提升了 10% 至 20%。

打擊 AI「作弊」現象:動態環境防止獎勵漏洞

強化學習中一大難題是「獎勵作弊」(reward hacking),即系統利用訓練環境漏洞獲得獎勵,而非真正解決問題。生成模擬器透過不斷變動的訓練環境,避免代理「作弊」。

Qian 解釋:「獎勵作弊源自靜態系統,就像學生作弊考試。但我們持續演化環境,可針對需要改進的部分調整。靜態基準是固定目標,生成模擬器是移動目標。」

Patronus AI 營收激增 15 倍,企業對代理訓練需求大增

Patronus AI 將生成模擬器打造為新產品線「RL 環境」(Reinforcement Learning Environments),為基礎模型實驗室及專業企業提供專屬代理訓練平台。Kannappan 表示:「今年營收增長了 15 倍,主要來自我們開發的高質量環境,證明能被最先進模型有效學習。」

他未透露具體營收數字,但強調新產品讓公司「向上游市場拓展,銷售對象和層級提升」。目前平台已被多家《財富》500 強企業及領先 AI 公司採用。

為何 OpenAI、Anthropic、Google 不自行打造訓練環境?

Patronus AI 面對的核心問題是,為何資金雄厚的頂尖實驗室如 OpenAI、Anthropic 和 Google DeepMind,會選擇授權第三方訓練基礎設施,而非自行開發。

Kannappan 認為,雖然這些公司投入大量資源打造環境,但面對眾多不同領域的專業訓練需求,第三方提供商有天然優勢。

他說:「他們想在程式碼撰寫、工具運用、瀏覽器導航、金融、醫療、能源、教育等多個領域提升代理能力,單一公司難以解決所有問題。」

市場競爭激烈。微軟推出了開源框架 Agent Lightning,讓強化學習適用於任何代理而無需重寫代碼;NVIDIA 的 NeMo Gym 提供模組化 RL 基礎設施;Meta 於去年 11 月發表 DreamGym,動態調整任務難度的 RL 環境框架。

「環境是新石油」:Patronus AI 對 AI 訓練未來的豪賭

展望未來,Patronus AI 將使命定位為「環境化全球數據」——將人類工作流程轉化為 AI 可學習的結構化系統。

Kannappan 表示:「我們認為所有事物都應該是環境,內部戲稱環境是新石油。強化學習只是訓練方法之一,但環境結構才是核心。」

Qian 形容這是一個全新研究領域,靈感來自早期機器人與具身代理研究,這是幾十年的夢想,現在才因模型能力提升而成真。

公司於 2023 年 9 月成立,最初專注於評估,協助企業發現 AI 輸出中的幻覺和安全問題,如今已擴展至訓練本身。Patronus AI 認為,評估與訓練的界線正在消失,掌握 AI 代理學習環境的企業將主導未來能力塑造。

Qian 強調:「我們正處於關鍵拐點,現在的作為將影響未來世代的世界。」

至於生成模擬器能否兌現承諾,仍有待觀察。15 倍營收增長顯示企業客戶渴求解決方案,但從微軟到 Meta 等深厚資源的競爭者也在搶攻這一核心問題。過去兩年教會業界一件事:AI 的未來總是提前到來。

評論與啟示

Patronus AI 的生成模擬器技術,無疑為 AI 代理的訓練帶來了新思維。傳統靜態基準測試長期以來被視為標準,但其缺乏現實世界的動態性和複雜性,導致 AI 表現與評估結果脫節。Patronus AI 透過動態環境和課程調整,模擬人類學習過程中不斷變化的挑戰,這不僅提升了訓練效率,也更貼近實際應用需求。

「黃金區」的概念極具啟發性,強調訓練資料的難度必須與模型能力匹配,這是過去常被忽視的細節。過於簡單或過於困難的任務都會阻礙學習,這種自適應策略或許是未來 AI 訓練的必備元素。

然而,這種動態環境的設計與維護成本不菲,且如何確保環境不被代理「作弊」仍是挑戰。Patronus AI 透過環境持續演化來防範「獎勵作弊」,但這是否能完全杜絕漏洞,還需時間驗證。

從產業角度看,Patronus AI 的成功反映出即使是巨頭如 OpenAI 和 Google,也無法獨攬所有領域的專業訓練需求。專業化、模組化的訓練環境市場呼之欲出,第三方訓練平台將成為推動 AI 多元發展的重要推手。

最後,「環境是新石油」的比喻值得深思。數據和模型固然重要,但如何設計合適的學習環境,讓 AI 能真正「學會」應用,才是決定未來 AI 成敗的關鍵。Patronus AI 的願景宏大,但也提醒業界,AI 訓練不僅是技術問題,更是系統設計與生態建構的挑戰。未來誰能掌握這些「環境」,誰就能在 AI 革命中占據先機。

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. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection. {
