OpenAI to pool ChatGPT and Codex usage allowance from December
According to OpenAI's help center, from December the usage allowance on Plus, Pro and Business plans will be shared between ChatGPT and Codex. The Chat and Work tabs in the desktop app are merging, and separate help pages cover GPT-6 Astra and Ultrafast usage.
Who is affected and how
- senior developer
- Codex and chat draw on one allowance, so schedule heavy agent tasks deliberately.
- tech lead
- Recalculate the team's subscription allowance, because Codex use will crowd out other ChatGPT use.
