Pangram 總部位於紐約,剛完成 900 萬美元融資。公司同時推出新一代 AI 文字偵測模型 Pangram 4,以及影像偵測模型 Pangram Image。投資者包括 Menlo Ventures、Haystack、ScOp、Script Capital 和 Cadenza。

文字偵測能力升級

新模型主打識別 AI 輔助寫作、混合人機內容,以及更常見的「AI 改寫工具」。 Pangram 稱,Pangram 4 對 AI 輔助文字的辨識準確率超過 99%。公司表示,這套系統不是依賴元資料或隱藏浮水印,而是透過大規模人類文字訓練後,再用對應的合成文本進行對照學習。

圖像模型進入預覽

Pangram Image 目前只開放研究預覽,後續幾週將擴大上線範圍。公司稱,這套影像偵測模型可以辨識不同 AI 模型產生的圖片,不只針對單一廠商的輸出。它是基於像素層面的統計差異來判斷內容來源。

面向平台和機構開放

Pangram 也提供網頁訂閱、Chrome 外掛和 API。外掛程式可在 X、LinkedIn、Substack、Reddit 和 Medium 上即時標註內容來源。公司稱,Substack 已把相關技術連接到平台,Quora、學校、出版社和招聘機構也是其 API 客戶。
