DAY 2.1 CLEARED

Day 2.1/

We have made Auto-review free for all users signed in through a ChatGPT account. You can enable it in settings > permissions > auto-review. Auto-review improves upon the default sandbox setting that requires you to approve everything, which is prone to decision fatigue unless you spend a lot of time configuring specific rules.

It allows you to run long tasks while having a second agent review all actions taken by the primary agent. Its only goal is to prevent high-risk actions from being taken and to protect against unwanted actions that are not aligned with the original user intent. This Auto-review feature is now free and does not draw usage from your plan.

Day 2.1/

我们为所有通过 ChatGPT 帐户登录的用户免费提供自动审核。您可以在“设置”>“权限”>“自动审核”中启用它。自动审核改进了默认沙箱设置,默认沙箱设置要求您批准所有内容,这很容易导致决策疲劳,除非您花费大量时间配置特定规则。

它允许您运行长时间任务,同时让第二个代理审查主要代理采取的所有操作。其唯一目标是防止采取高风险操作,并防止与原始用户意图不一致的不需要的操作。此自动审核功能现在是免费的,不会占用您的计划的使用量。
