騰訊混元於4月23日發佈並開源Hy3preview語言模型，這是一個融合快慢思考的混合專家模型，總參數295B，激活參數21B，支持256K上下文。作爲重建後訓練的首個模型，它在複雜推理、指令遵循、上下文學習、代碼和智能體等能力上顯著提升，是混元迄今最智能的模型。2026年2月，騰訊混元重建了預訓練和強化學習基礎設施，注重模型實用性。
騰訊發佈開源AI模型Hy3Preview，參數達295億，支持長上下文，在推理、指令遵循和代碼處理等方面表現提升，強調實用性、真實評測和高性價比。
騰訊推出新一代AI大模型混元3.0（Hy3），在編程能力方面表現突出。該模型由AI專家姚順雨加盟後性能顯著提升，目前以Hy3preview名義在openrouter上免費開放體驗。
