騰訊混元與WorkBuddy聯合發佈Hy4 preview升級公告，針對用戶反饋的複雜任務長思考、過度自我驗證等問題進行專項優化並全量上線。經Bench指標與人工評測雙重驗證，新版在保持任務效果的同時，顯著降低任務輪次及輸入輸出消耗。
9月7日，騰訊混元與WorkBuddy聯合團隊宣佈混元Hy4preview模型升級全量上線。此次升級基於用戶與開發者反饋，專項優化複雜任務下長思考、過度自我驗證等問題，並通過Bench指標與人工評測雙重驗證，確保優化不犧牲任務效果。
據OpenRouter數據，8月31日至9月6日全球AI大模型調用量115萬億Token，環比增1.77%。中國模型周調用量56.72萬億Token，環比增2.83%，連續19周超美國居首；美國16.54萬億，環比降3.1%。全球前五中四款中國模型，混元Hy4 preview登頂。
姚順雨稱大模型並無祕密，騰訊混元4（Hy4preview）近期表現印證此言。面對智譜、月之暗面、DeepSeek、千問等競爭，騰訊四個月內完成混元大語言與多模態部門重組，推出770B參數、支持百萬上下文的模型，顯示所謂技術壁壘並非不可逾越。
