    Import AI 455:AI 系统即将开始自我构建

    Import AI 作者 Jack Clark 认为,AI 系统很可能在 2028 年底前实现无人类参与的 AI 研发,即前沿模型能自主训练出自己的后继版本,他给出的概率是 60% 以上,2027 年前实现的概率约为 30%。他依据公开数据梳理证据链:SWE-Bench 从 Claude 2 的约 2% 升至 Claude Mythos Preview 的 93.9%,METR 时间跨度从 2022 年 GPT 3.5 的约 30 秒升至 2026 年 Opus 4.6 的约 12 小时,CORE-Bench、MLE-Bench、PostTrainBench 以及 Anthropic 的模型训练优化任务也显示 AI 在核心研发环节快速进步。他认为 AI 目前尚不能提出颠覆性新想法,但 AI 研发大量属于可自动化的工程性工作,且 OpenAI、Anthropic、DeepMind 及多家初创公司都在明确追求自动化 AI 研发。

    Google Photos 上线 Auto frame,可重新调整已拍照片的拍摄角度

    Google Research 宣布在 Google Photos 的 Auto frame 功能中上线一种新的图像编辑方法,让用户在照片拍完后重新调整拍摄视角。该方法把 2D 照片理解为 3D 场景,先用内部 3D 点图估计模型还原人体和面部并推算原相机焦距,再用经典 3D 渲染生成新机位下的画面,最后用生成式潜在扩散模型填补新视角下原本未拍到的背景空洞。该功能已作为 Auto frame 候选中的第二个版本选项上线,可自动检测人脸位置与朝向并计算理想取景参数,也会修正广角前置摄像头造成的透视畸变。
