谷歌Chrome和微软Edge浏览器相继更新了系统要求，规定用户设备需预留约20GB可用磁盘空间才能下载本地AI模型[1]。这一变化反映了两大浏览器厂商在本地部署AI功能方面的新策略。
具体来看，Chrome浏览器允许在设备本地运行AI功能[1]，用户可在"设置>系统"中关闭设备端AI功能[1]。微软Edge对硬件的要求更为严格，除了需要20GB可用磁盘空间外，还要求GPU显存至少5.5GB[1]。微软Edge还设置了自动清理机制，当设备可用空间低于10GB时，本地AI模型将被自动删除[1]。此外，两款浏览器均要求用户必须使用不限流量或非按流量计费的网络[1]。
早在今年5月，Chrome就曾被发现会自动向符合条件的PC下载约4GB的AI模型[1]。
Google Chrome and Microsoft Edge have updated their system requirements, mandating that users reserve approximately 20GB of available disk space to download local AI models [1]. Both browsers are moving to run artificial intelligence features on devices locally, reducing reliance on server uploads [1].
Microsoft Edge has imposed additional constraints beyond Chrome's storage requirement, specifying that graphics processing units must have at least 5.5GB of dedicated memory [1]. Edge has also implemented an automatic cleanup mechanism that deletes locally stored AI models when available disk space falls below 10GB [1]. Chrome automatically downloads approximately 4GB of AI models to qualifying PCs [1]. Both browsers additionally require connection to an unlimited or non-metered network for model downloads [1].
Chrome users who wish to avoid these requirements can disable the on-device AI functionality through Settings > System [1]. The storage and hardware demands reflect the significant computational footprint of running advanced language models locally, a shift that has raised concerns among users regarding both privacy implications and storage occupation on personal devices [1].
