微软11月29日向Windows 11 Copilot用户推送更新：免费开放GPT-5.1模型，一键启用原付费“Think Deeper”深度推理功能。新增“Labs”实验区，首批上线WinUI 3“Vision”实时画面解析组件，后续将逐步加入3D生成、音频表达等功能。“Actions”特性正在内测中。
微软Copilot新增音频模式，基于MAI-Voice-1模型提供三种语音选择：情感模式支持富有表现力的自由表达；故事模式适合多角色讲故事；脚本模式则用于精确的文本朗读。
微软推出实验性AI中心Copilot Labs，邀请用户参与AI创新。平台提供实验工具，鼓励社区共同塑造Copilot未来。首个工具“Copilot音频表达”可将文本转为自然语音，用户可灵活调整音效。
