Why we picked it

IFM 把草莓换成橡皮鸭，模型能算出两次水花有什么不同，这是把物理规律内化进世界模型的做法。做智能体规划的人可以看看这种"先推演再执行"的思路，和 Sora 类纯视频生成模型方向不太一样。

IFM（Institute of Foundation Models）发布世界模型 PAN 2，官方演示展示了一个核心场景：往碗里放入一颗草莓后，可以将草莓替换成橡皮鸭，或更换碗中的液体，模型会模拟每种版本并预测水花的变化。

Body

PAN 2 的设计目标是让模拟建立在时间、物理和空间三个维度之上，分别对应官方放出的三段演示。IFM 的设想是让 AI 智能体在实际行动之前，先用 PAN 2 对 what-if 场景做推演，评估不同操作的后果。

这类"先模拟、后行动"的思路，将世界模型定位为智能体规划能力的底层组件，与单纯生成视频的模型形成差异。

Drop a strawberry into a bowl. Now make it a rubber duck. Or change the liquid.

PAN 2, the world model the Institute of Foundation Models (IFM) just launched, simulates each version and shows how the splash changes.

IFM built PAN 2 to be grounded in time, physics, and space. The idea is that AI agents can check a what-if like this before they act. Below are three more demos, one for each.

Chinese contentIFM 开源世界模型 PAN 2，用模拟式推理让智能体先演练再行动

IFM 把世界模型做成了智能体的"预演器"：29B 的 LDM 负责画后果，LLM 负责想后果，选最优再动手。和纯文本推理的 agent 框架相比，它多了视频级的可视化验证。做机器人、游戏或决策型智能体的开发者可以直接下载权重和代码上手试。

Chinese contentMBZUAI 旗下 IFM 发布开源世界模型 PAN 2：29B 参数可模拟 20 秒动作结果

阿联酋 MBZUAI 的 IFM 实验室开源了 PAN 2，用 29B 扩散模型加 LLM 规划器，能预演最长 20 秒的物理动作结果。做机器人或具身智能的团队可以自己部署跑起来，不用从零搭仿真环境，Apache 2.0 许可商用也没障碍。

MBZUAI's IFM Releases PAN 2 Open World Model

The ablation numbers reveal that planning, not visual fidelity, is the bottleneck in multi-step world-model tasks, a finding that will shape how teams architect embodied agents. Robotics researchers and agent builders can use the open weights to benchmark simulative reasoning pipelines against proprietary alternatives. As a UAE-based lab's release, it adds a non-US, non-China option to the open world-model landscape, relevant to ASEAN academic teams seeking accessible baselines.
