字節跳動啓動“豆包股”首次回購，價格13.08美元，較授予價上漲約30%。此舉反映其大模型業務估值增長，爲相關技術人員提供收益與退出渠道。該計劃是公司去年10月推出的長期激勵措施。
字節跳動AI核心部門Seed團隊近一年流失近70名技術人才，流向頭部大廠及AI初創公司，反映國內大模型人才競爭白熱化。該團隊成立於2023年，專注LLM、語音、視覺及世界模型等前沿研究，其豆包大模型已支持豆包、釦子等50多個應用場景。
字節跳動發佈原生全雙工語音大模型Seeduplex，實現“邊聽邊說”同步處理，推動AI語音交互從“回合制”向“實時自然交互”演進。該技術已在豆包App全量上線，完成億級用戶規模化落地。
上汽通用與火山引擎合作，將豆包大模型引入別克至境E7，推動智能座艙從“指令交互”升級爲“語義理解”。新系統能識別20多種情緒，通過語調、語速感知用戶心情，實現從“執行工具”到“理解者”的轉變。
