耶魯學者倡CCAI授權：你用開原始碼訓練AI，就要公開模型架構

Q: 首先要驗證的關鍵點是什麼？

CCAI係耶魯DEC提出嘅新型授權框架，旨在將傳統「Copyleft」原則延伸到生成式AI領域 [3][4]。 核心概念係將經受保護開源程式碼訓練嘅AI模型，視為該程式碼嘅「衍生著作」，從而觸發Copyleft義務 [3][4]。

AI公司長期被批評「食免費午餐」——佢哋用GitHub等平台上面嘅開源程式碼訓練自家嘅閉源AI模型，賺到盆滿缽滿，但開發社群就乜都收唔返。耶魯大學數位倫理中心（DEC）嘅研究團隊近日就提出一個可能嘅解決方案：情境式Copyleft AI授權（Contextual Copyleft AI License，簡稱CCAI），嘗試用法律框架逼使AI開發者「回水」畀開源社群。

CCAI係咩玩法？將Copyleft概念搬去AI世界

Copyleft本身係自由及開源軟件（FOSS）世界嘅概念，最基本嘅運作原理係：你可以自由使用、修改、散佈呢個軟件，但任何衍生作品都必須繼續沿用同樣嘅開放授權條款，唔准「鎖返埋」變做閉源產品。

CCAI嘅核心諗法，就係將呢個原則由傳統軟件延伸去生成式AI模型。根據呢個授權框架，一個用受CCAI保護嘅開源程式碼訓練出嚟嘅AI模型，會被法律上視為該程式碼嘅「衍生著作」（derivative work） 。換句話講，你只要拎人哋嘅開源碼去「餵」你個AI，你個AI本身就即刻跌入Copyleft嘅管轄範圍，必須遵守相同嘅開放規則。
