## AI 摘要

OpenAI 回应 Codex 用量限制差异：未与社区沟通前不会擅自更改。调查发现受影响用户多通过 sub2api 将订阅转为 API 流量再分发共享，此类行为会被欺诈预防系统标记。通过 Sign in With ChatGPT 在官方或 OSS 客户端（如 Pi、OpenCode）正常使用订阅则完全没问题。

## 正文

We've investigated a few messages about codex usage limits being different. That's not something we change without engaging the community and being transparent.

What we did see is that when talking to affected users many were using sub2api. Converting a subscription into api traffic to then re-serve or share across many users is not something we support and this type of usage gets flagged by our fraud-prevention systems.

You are completely fine if you use your subscription through Sign in With ChatGPT, either through the official clients or through one of the many OSS clients (Pi, OpenCode, ...) that support signing in with your account and using your included usage.
