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。

All right, we’re locking in. Only things being worked on are simplifications, more efficiency for more usage, groundbreaking features or new models.

Sometimes you have to invest ahead of the curve, but feedback is clear that you all want things to get simpler. On it.

好吧，我们正在锁定目标。唯一要做的就是简化、提高使用效率、突破性功能或新模型。

有时你必须提前投资，但反馈很明显，大家都希望事情变得更简单。在它上面。
