5.6 上下文怎么缩回 258k 了

大家抱怨 token 消耗太快，又改回去了

@molvqingtai #1 原来就是这样解决的吗。离谱

@molvqingtai 笑死

准确说是 272K ，之前是 372K 。TiBo 原文：- We have landed inference optimizations and are passing down savings to all the subscriptions for GPT-5.6 Sol. That should result in around 10% more usage on its own.
- We noticed that by changing the context size limit in the product to 372k for GPT-5.6 Sol, up from 272k for GPT-5.5, it resulted in more usage being charged than intended. We have reverted to 272k and will work to roll back out to 372k in the days to come. You should notice that usage drains significantly less after this change.
- To understand where the extra usage was coming from, we ran some experiments where reasoning efforts were changed (referred to as juice values under the hood) and have reverted this.
- There is slightly more usage of multi-agent than intended in high and xhigh reasoning effort, we are fixing this going forward. Also fixing a small other thing we noticed with auto-review where we can be more efficient.

@honjow #2 应该是临时解决，估计哪些地方有 bug
