为了在具身环境中解决复杂任务，智能体需要深入理解世界并选择成功的行动。世界模型通过学习从智能体（如机器人或电子游戏玩家）的视角预测潜在行动的 未来结果，为实现这一目标提供了一种有前景的方法。 通过这种方式，世界模型使智能体能够深入理解世界，并具备通过在想象中进行规划或强化学习来选择行动的能力。此外，原则上世界模型可以从固定数据集中 学习，这使得智能体能够纯粹在想象中进行训练，而无需在线交互。对于许多实际应用而言，离线优化行为很有价值，例如物理世界中的机器人，在这种情况 下，与未充分训练的智能体进行在线交互往往不安全。 世界模型智能体 —— 如 Dreamer 3—— 是迄今为止在游戏和机器人领域表现最佳且最为稳健的强化学习算法之一。虽然这些模型在其特定的狭窄环境中速度快且 准确，但其架构缺乏拟合复杂现实世界分布的能力。可控视频模型，如 Genie 3，已在多样的真实视频和游戏上进行训练，并实现了多样的场景生成和简单交互。 这些模型基于可扩展架构，如 diffusion transformer。然而，它们在学习物体交互和游戏机制的精确物理规律方面仍存在困难，这限制了它们在训练成功智能体方面 的实用性。此外，它们 ...
