    研究者将 LeCun 的 JEPA 扩展为跨物理到生物的通用世界模型

    PhAI Labs 联合 Stanford、Oxford、Princeton 提出 JEPA-Anything,把 JEPA 的单一预测拆成多个专用预测模块,并让各模块在训练中分化出不同角色,从而用同一套架构覆盖物理、机器人、天气、单细胞和临床等七个领域。在简化 Pong 环境中预测误差下降 35%,未见过的干预组合下降 13%,Burgers 方程基准误差接近减半,但 50 步后优势缩小到约 3%;模拟行走机器人规划中三环境赢下两个。团队还从生物数据中筛出 IL-18 联合 CD73 阻断的肝癌候选方案,并在类器官、患者组织和小鼠中测试,论文同时指出这尚不能说明可成为疗法,代码与模型已公开。

    JEPA-Anything提出并排序实验,然后将结果反馈给模型。代码和模型已公开。 LeCun于2022年提出JEPA,作为生成模型的替代方案。2025年6月,Meta发布了V-JEPA 2,这是一个拥有12亿参数的JEPA视频模型,无需额外训练即可在陌生环境中控制机械臂。2025年11月,LeCun与Randall Balestriero随后推出了LeJEPA,这是一个旨在无需常规变通手段即可保持训练稳定的理论基础。LeCun目前正通过其初创公司AMI Labs推进这一方法,该公司于2026年3月融资超过十亿美元,用于构建世界模型。 Google Deepmind已于2025年10月在实验室中测试了一个由AI生成的癌症假说。其基于Gemma的模型C2S-Scale 27B提出使用药物silmitasertib使肿瘤细胞更容易被免疫系统识别,而利用人类细胞模型进行的实验证实了这一预测。Google Deepmind的多智能体系统Co-Scientist如今能够规划实验并操作实验室设备,覆盖了JEPA-Anything团队想要构建的循环中的部分环节。不过,将样本装入机器仍然需要人工完成。

    马里兰大学与 AWS 提出 LEGO-Anything:编码智能体从单张照片生成可编辑 3D 场景

    马里兰大学与 AWS 的研究者提出 LEGO-Anything,让编码智能体接收单张图片后编写并迭代修改 Blender 代码,生成可运行、可编辑的 3D 场景程序。配套的 LEGO-Bench 包含 104 个室内外场景的 208 张图像和 443 个注册资产,从有效性、几何重建和外观三方面评分。测试中六种 GPT 配置几乎都能交付可用场景,但几何准确率差异很大,表现最好的 GPT-6 Astra 在室内场景为 53.4%、室外为 39.6%,较弱配置约 15%;研究者发现智能体在判断两个版本哪个更接近原图时准确率接近或低于随机水平,据此提出无需额外训练的 LEGO-Plugin,使较弱智能体提升最高达 62.7%。

    Runway 详解 GWM Worlds 2 的 WorldPrompt 与实时世界生成工程

    Runway 本月推出研究预览版 GWM Worlds 2,把高保真视频与音频生成变成实时交互式模拟,并提出 WorldPrompt 输入格式,可固定首帧等环境要素后按时间戳编排事件。该模型以 720p、24fps 视频和 48000Hz 音频流式输出,做法是先微调基础音视频模型以适配 WorldPrompt,再后训练为自回归生成,最后用蒸馏做到实时。CTO Kamil Sindi 与首席研究科学家 Robin Kahlow 表示,自回归模型的误差累积、长时记忆和上下文取舍仍是待解问题,模型也没有结构化状态可供智能体读取。

Alongside Runway, there are several other notable projects in this domain: Google DeepMind’s Genie 3 (which also generates at 720p and 24 fps), Odyssey-2 Pro , and World Labs’ RTFM (Real-Time Frame Model).
