Day 7 receipt
ChatGPT and Codex shared usage allowance
Day 1 of 7Not a launch yet: OpenAI updated its help page on 31 Oct 2026 saying the change starts 'in December'. No exact start date is given. Subscribers also report an email, and an earlier checkout notice was spotted on 29 Oct.
OpenAI says that from December the usage allowance on three paid plans will be shared across ChatGPT and Codex, counted in tokens, with Instant chat left out.
Launch dayWhat they claimed, quoted word for word · 4
“Starting in December, Plus, Pro, and Business plans’ usage allowance will be shared across ChatGPT and Codex”
Not yet in effect. No exact date in December has been given, and outlets note the page does not cover Free, Enterprise or Edu plans.
“Your usage for ChatGPT and Codex will be measured in tokens”
No token amounts per plan are published, so users have nothing to compare against today's limits.
“Instant chat will not draw from your usage.”
Outlets point out the page does not define which model counts as Instant once Work is folded into the main app. Nothing to test until the change is live.
“We expect most users won't need to wait for their usage to reset more often than they do now.”
A forward-looking expectation with no figures behind it. Several commenters who use chat and Codex together say they expect to hit limits sooner.
Day 7What real users report · 4
A subscriber says they received an email from OpenAI saying chat and work are coming together, with the shared allowance for ChatGPT and Codex as the real headline.
A Plus subscriber who almost never uses the coding side says they will keep the plan until the merge and leave if it limits their chat use, and notes that Instant seems set to stay unlimited.
A researcher on the top plan says a main reason they pay OpenAI is that the strongest chat model and Codex are billed separately, which the shared allowance appears to end.
A commenter says not losing everyday queries when coding usage runs out was a big plus of ChatGPT and Codex over Claude, and the shared pool removes it.
