OpenAI 为 Codex 和 ChatGPT Work 用户推送更新，核心是优化推理效率并降低使用成本。主要变化包括：落地推理优化，使 GPT-5.6 Sol 订阅用户获得约 10% 的额外使用量；将上下文窗口从 372k 回退至 272k（此前从 272k 提升至 372k 导致用量超预期），后续将重新推出；调整了推理努力（juice values）实验并回滚；修复高/极高推理努力下多智能体使用量略超预期的问题，以及 auto-review 的效率问题。5 小时限制继续暂时取消。

Updates for Codex and ChatGPT Work users. No nerfing, only good stuff!
- 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.
And we continue to have the 5h limit temporarily not apply. Enjoy the rest of the weekend!
OpenAI has reduced GPT-5.6 Sol's thinking budgets in an effort to make the model more efficient They essentially bumped everyone's reasoning down by 1... so if you were running Sol Extra High, you now have to set it to Max to get the same effort So we basically don't have Max reasoning anymore, how do you feel about these changes? 🤔在 X 查看被引用的帖子
