生成NPC为交互应用程序创建逼真的人类行为模拟。在这项工作中，我们通过将二十五个NPC放置在一个沙盒环境中（类似于The Sims，模拟人生），展示了生成NPC的能力。用户可以观察和干预NPC的日常计划、分享新闻、建立关系以及协调团体活动。
1.整体介绍
可信的人类行为NPC可以赋能各种交互式应用，包括沉浸式环境、人际交流排练空间、原型工具等。在本文中，我们介绍了生成NPC——计算软件代理，模拟可信的人类行为。生成NPC会起床、做早餐、去上班；艺术家绘画，作家写作；他们形成意见，关心彼此，并发起对话；他们回忆和反思过去的日子，规划着未来。
为实现生成NPC，我们描述了一种架构，扩展了一个大型语言模型，使用自然语言存储NPC完整的经历记录，随着时间的推移将这些记忆综合成更高层次的反思，并动态检索它们来规划行为。我们实例化生成NPC以填充由The Sims启发的交互沙盒环境，使用自然语言与二十五个NPC的小镇进行交互。在评估中，这些生成NPC产生了可信的个体和涌现出了社会行为：例如，从仅有一个用户指定的观念开始，即一个NPC想要举办情人节聚会，NPC自主地在接下来的两天里传播聚会的邀请，结交新朋友，邀请彼此参加聚会，并协调好一起在正确的时间出现聚会。我们通过实验证明，我们NPC架构的组件——观察、规划和反思——每个都对NPC行为的可信度有关键影响。通过将大型语言模型与计算、交互NPC融合，本工作引入了架构和交互模式，以实现可信的人类行为模拟。
2.场景角色解析
Smallville拥有一个小型村庄的共通设施，包括咖啡馆、酒吧、公园、学校、宿舍、房屋和商店。它也定义了子区域和物体，让这些空间变得功能性，比如房子里有厨房，厨房里有炉子。所有被NPC当作主要居住区的地方都有床、书桌、壁橱、架子、浴室和厨房。
先介绍整个小镇地图的设计规划，然后展开生活在这个小镇上每个人物角色设定，便于后续观察和研究其互动行为。

3.角色行为交互
3.1.NPC交流方式
3.1.1.NPC内部交流
NPC之间的交互通过行动和自然语言实现。在每个沙盒引擎的时间周期中，NPC输出一个描述其当前行动的自然语言语句，例如“Isabella Rodriguez正在写她的日记”、“Isabella Rodriguez正在检查邮箱”、“Isabella Rodriguez正在和家人通电话”或“Isabella Rodriguez正在准备睡觉”。这个语句然后被翻译成影响沙盒世界的具体动作。这个行动在沙盒界面上显示为一组表情符号，提供一个俯视图中行动的抽象表示。
为了实现这一点，系统采用了一个语言模型，将行动翻译成一组表情符号，这些表情符号出现在每个头像上方的对话气泡中。可以通过点击NPC头像来查看行动的完整自然语言描述。NPC之间以完整的自然语言进行通信。NPC知道周围区域中的其他NPC，生成式代理架构决定他们是否经过或参与对话。
3.1.2.用户控制
运行此模拟的用户可以操纵模拟并进行干预，可以通过与NPC的对话进行交流，也可以通过向NPC发出“内部声音”形式的指令进行干预。
（1）用户通过自然语言与NPC交流，通过指定NPC应该认为他们是什么人物角色来进行交流。例如，如果用户指定自己是一个新闻“记者”，并询问关于即将到来的选举，“谁在竞选职位？”
（2）为了直接指挥其中一个NPC，用户会扮演NPC的“内部声音”的角色，这使NPC更有可能将该语句视为指令。例如，当用户作为John的内心声音告诉他“你将要在即将到来的选举中与Sam竞选”，John决定参选，并与他的妻子和儿子分享了他的候选人身份。
3.2.NPC与环境交互
NPC在Smallville里的移动方式就像在简单的视频游戏里一样，进出建筑物、浏览地图并向其他NPC靠近。NPC的移动是由生成式代理构建和沙盒游戏引擎控制的：当模型规定NPC要前往某个地方时，我们会在Smallville环境中计算到目的地的步行路径，NPC开始移动。此外，用户还可以作为NPC进入Smallville的沙盒世界运作。用户所化身的NPC可以是已经存在于世界中的NPC，例如Isabella和John，或者是一个没有先前历史的外来访客。Smallville的居民不会对用户控制的NPC有任何不同的待遇。他们会认识到其存在，发起互动，并在形成对它的看法之前记住其行为。
用户和NPC可以像沙盒游戏The Sims一样影响这个世界中物体的状态。例如，当NPC睡觉时，床可以被占领；当NPC用完做早餐的材料时，冰箱可以变空。最终用户也可以通过使用自然语言来重新塑造Smallville中NPC的环境，改变NPC周围物体的状态。例如，当Isabella在早上做早餐时，用户可以通过向系统输入一个命令来选择对象并说明其新状态，将厨房炉子的状态由“打开”更改为“燃烧”，像这样：<Isabella的公寓：厨房：炉子>正在燃烧。Isabella会在下一刻注意到这一点，并关闭炉火重新做早餐。同样，如果用户将Isabella浴室的状态设置为“渗水”，当她进入浴室时，她会从她的客厅取工具来修理漏水的地方。
3.3.涌现出来的社会行为
信息扩散：当NPC注意到彼此时，他们可能会开始对话。在这个过程中，信息可以从一个NPC传递到另一个NPC。
关系记忆：Smallville中的NPC随着时间的推移建立新的关系，并记住他们与其他NPC的互动。
协作：生成式NPC相互协作。
