階躍星辰正式發佈並開源Step5Preview模型權重，面向全球開發者公開BF16與FP8權重、技術博客及配套開源開發工具。該模型此前在OpenRouter周榜、日榜調用量排名中一度穩居全球第二。架構上，它專爲長程複雜智能體任務深度優化，採用稀疏MoE架構，總參數量高達600B。
聯想與海爾在京簽署戰略合作，楊元慶、周雲傑見證。雙方圍繞AI產業落地，以“算力賦能實體、場景反哺技術”爲主線，覆蓋一體化數據中心、液冷、家用機器人等五大領域，推動算力與場景深度融合，探索AI賦能實體經濟新路徑。
據OpenAI內部消息，ChatGPT周活躍用戶即將突破10億，里程碑晚於原計劃約7個月。但上線不到四年獲此規模，仍是全球增速最快產品之一。發言人未予置評。增長放緩背後，谷歌Gemini深度整合數十億用戶生態，競爭加劇，增長引擎逐漸換擋。
螞蟻集團副總裁周俊在AICon大會上強調，萬億參數模型算力成本驚人，每運行15分鐘即消耗一輛特斯拉的費用，效率成爲智能體時代核心挑戰。他提出顛覆性策略，推動行業從盲目追求“更多”轉向突破效率瓶頸。
