字节跳动启动“豆包股”首次回购，价格13.08美元，较授予价上涨约30%。此举反映其大模型业务估值增长，为相关技术人员提供收益与退出渠道。该计划是公司去年10月推出的长期激励措施。
字节跳动AI核心部门Seed团队近一年流失近70名技术人才，流向头部大厂及AI初创公司，反映国内大模型人才竞争白热化。该团队成立于2023年，专注LLM、语音、视觉及世界模型等前沿研究，其豆包大模型已支持豆包、扣子等50多个应用场景。
字节跳动发布原生全双工语音大模型Seeduplex，实现“边听边说”同步处理，推动AI语音交互从“回合制”向“实时自然交互”演进。该技术已在豆包App全量上线，完成亿级用户规模化落地。
上汽通用与火山引擎合作，将豆包大模型引入别克至境E7，推动智能座舱从“指令交互”升级为“语义理解”。新系统能识别20多种情绪，通过语调、语速感知用户心情，实现从“执行工具”到“理解者”的转变。
