# OpenAI checkout notice: from December, ChatGPT and Codex will share one plan usage limit

A ChatGPT checkout notice spotted on Nov 2, 2026 says 'Starting in December, plan usage will have a shared limit across all of ChatGPT and Codex'. OpenAI has not announced it publicly or said how usage will be counted or which tiers are affected.

## Key facts
- Notice text: 'Starting in December, plan usage will have a shared limit across all of ChatGPT and Codex' (Windows Report)
- Seen on what appears to be the Plus checkout page; reports say Instant chats are exempt (unverified)
- No OpenAI help-centre page or post found as of Nov 3
- Related: TechCrunch (Nov 2) reports OpenAI is merging ChatGPT's Chat and Work tabs; Codex lead Tibo Sottiaux posted on Oct 28 (~1.81M views) that the merge was being worked on but 'not rolling out just yet'

## What happened
