MAI 模型使用 Common Crawl，尽管承诺了“清洁数据”
微软的技术论文揭示 MAI-1 的训练使用了 Common Crawl 和未授权的网络数据，这与其关于仅使用企业级、商业许可数据的声明相矛盾。
microsoft's technical paper for maia-1 reveals that the models were trained on common crawl and other publicly available, unlicensed web data. this finding contradicts microsoft's explicit marketing promises that the models were built using only enterprise-grade, clean, and commercially licensed datasets. while microsoft claims to respect robots.txt and standard web protocols, it effectively shifts the burden of content protection to site owners rather than securing explicit licensing. this highlights the ongoing discrepancy in the industry between marketing 'clean' ai products and the legal reality of relying on fair use for training data.
