Anthropic指控中國AI新創公司「智譜」曾試圖透過蒸餾技術竊取模型能力,並宣布將大幅減少模型推理資料的擷取量。
美國AI公司Anthropic宣布新防護措施,透過限制模型推理資料擷取,大幅降低競爭對手利用「模型蒸餾」複製Claude能力的風險。公司並點名中國智譜AI曾試圖以此方式開發自家模型,目前已封鎖數萬個相關帳號。
AI-generated summary
模型蒸餾技術允許競爭對手透過探查先進模型輸出,以較低成本複製其推理能力。Anthropic將此視為保護知識產權與國家安全的必要手段。
美國人工智慧(AI)公司Anthropic 12日表示,為了防範競爭對手透過「模型蒸餾」技術,複製其AI模型Claude能力,已祭出新措施,使「蒸餾」能夠擷取的資料量大幅減少90%到99%。Anthropic並點名中國AI新創公司「智譜」,指其曾試圖以「蒸餾」方式開發自家模型。
路透12日報導,Anthropic指出,新防護措施限制外界取得Claude的推理內容,大幅減少資料遭擷取,蒸餾者能擷取的推理詞元(reasoning tokens)數量,現在「已降低到之前的10分之1到100分之1」。該公司也提高利用「代理網路」反覆探查Claude受保護推理內容的難度,阻擋資料擷取行為,並使大規模模型蒸餾更難以進行。
隨著美中AI競爭加劇,「模型蒸餾」已成為領先AI業者一大關切問題。Anthropic、OpenAI及Google等公司認為,競爭對手可利用這種做法以更低成本、更快速度,複製先進AI模型的能力。
Anthropic表示,這套防護機制的安全程度,大約相當於「防止Claude被用於協助製造生物武器的安全系統」,並且「誤判率低於0.1%」。
該公司已封鎖數萬個與模型蒸餾活動有關的帳號,並點名中國AI新創公司「智譜」(Z.ai),指其在開發GLM-5.3模型期間,曾試圖從Claude「蒸餾」取得相關能力。Anthropic警告,這類行為可能帶來安全和國安風險。智譜尚未回應此事。
