On October 6, 2026, Tibo announced the Day 2.1 improvement, saying Auto-review is free for all users signed in through a ChatGPT account and no longer draws from plan usage. OpenAI's Codex plan documentation updated the same day confirms this rule and states that other Codex activity remains subject to normal usage limits and applicable charges. This should not be described as all Codex usage becoming free, an increase in quota, or a quota reset.
The exact backend activation time was not separately published.
