ChainCatcher message, August 21: OpenAI responds to differences in Codex usage limits, stating that it will not change the related rules without communicating with the community first. The official investigation found that affected users mostly convert subscriptions into API traffic via sub2api and then redistribute and share them; such behavior will be flagged by anti-fraud prevention systems.

OpenAI said that using subscriptions normally via Sign in With ChatGPT in official or OSS clients (such as Pi and OpenCode) is completely fine.
