这是通过“二次预训练”实现的，第一次预训练，我们让模型知道各个物体是什么；第二次预训练，我们通过“热力图”让模型重点关注操作对象，让模型学会分辨“什么才是当前任务最重要的东西”。
There is a plan to prevent such a strike—the Space Surveillance Network, a bevy of sensors that the military uses to track space debris. NASA monitors what’s unofficially known as the “pizza box,” a sort of no-fly zone around the ISS. When pieces of debris are predicted to enter the box—if there’s at least a 1 in 100,000 chance of collision—mission controllers order avoidance maneuvers, firing thrusters that move the ISS and dodge the trash. The technique has been used dozens of times since the first ISS module launched in 1998. But the system only tracks about 45,000 larger pieces, and all sensors have noise. Plus, risk thresholds can miss stuff, sometimes badly. In 2025, Chinese astronauts were briefly stranded at their station after debris hit their return vehicle.

第二天，销售回复开始涌入。Stuyvenberg 让 AI 继续操作：每隔几分钟检查邮件，把最低报价转发给其他经销商，要求他们“看看能不能给出更低的价格”。当销售试图打电话或发短信推进沟通时，AI 礼貌地把对话引回邮件，让整个流程更可控。
值得一提的是，近期 Google 正式发布了其最新 AI 模型 Genie 3 以后，便有不少声音开始担忧 AI 技术对传统游戏开发底层的颠覆性冲击。
