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!

Morning. The last 48 hours of Codex and ChatGPT Work have been intense! Three important updates: - Temporarily removing the 5 hour usage limit restriction for all Plus, Business and Pro plans - Rolling out changes that will make GPT 5.6 Sol more efficient across the board and that will be reflected in less usage being used so that it can take you further. Exact impact to be quantified and shared - We hit 6M active users, and are landing a usage reset in the next hour Go do things

We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’s weekly rate limits 50% higher, through July 19.

终于知道 Codex 5.6 跑长任务时，额度为什么可能掉得特别快了。 GPT-5.6 Sol 基础价没涨。 但输入一旦超过 272K tokens， 整次请求都会按更高价格计算。 同样一次长任务，成本可能达到 GPT-5.5 的 2.34 倍。👇

GPT-5.6 系列模型新增了一个很糟糕的设计，会大幅降低模型性能。 在 Codex 里默认 tool_mode = code_mode_only。 code_mode 是 Codex 新增的一个功能，允许模型写一段 JS 脚本，同时执行多个动作。 本来是好事，但现在明显过头了，连 read、write 这些基础动作都要写 JS 脚本执行。

This is misinformation. Your tokens are not being billed at a higher rate over 272k tokens with the new expanded context window with the 5.6 family of models. If you manually expand the context window beyond that however, that’s a different story.

体验下来似乎 gpt-5.6-sol 更喜欢用 skill 了？（就是根据 meta 头去匹配用什么 skill） 感觉是好事，给一些有 cli 的 skill 和 tool 同等的地位了，不过对于 skill 装很多的人来说可能不那么好（
