ChatGPT and Codex Will Share One Limit in December

ChatGPT and Codex will share one usage limit from December, OpenAI says in a help article. It names the Plus, Pro and Business plans, says usage will be measured in tokens, and says Instant chat will not draw from your usage. It gives no day in December and no size for any plan. Nor did the other OpenAI pages we could open on November 3; three OpenAI help pages would not open for our reader.
