Hidden ChatGPT Checkout Text Says Plan Usage Will Share One Limit Across ChatGPT and Codex Starting in December
ChatGPT web app now has a new hidden shared usage limit checkout disclaimer - "Starting in December, plan usage will have a shared limit across all of ChatGPT and Codex"
Context
If it ships, heavy Codex users would draw down the same allowance they use for everyday ChatGPT, changing how much paid plans are really worth for coders and casual users alike.
Codex is OpenAI's coding agent, included with ChatGPT plans. OpenAI's help pages currently say Codex and ChatGPT Work share one usage allowance, while regular ChatGPT Chat has separate message limits. Tibor Blaho is an independent developer who regularly finds unreleased features in OpenAI's apps. This is a secondhand finding from app text, and OpenAI has not announced the change.
Deep dive
Tibor Blaho, who tracks unreleased changes in OpenAI's apps, posted on Thursday evening that the ChatGPT web app has a new hidden disclaimer on its checkout page. His screenshot shows the line: Starting in December, plan usage will have a shared limit across all of ChatGPT and Codex, followed by a Learn more link.
Today OpenAI's help pages describe a split. Codex, ChatGPT Work and some other agent features draw from one shared allowance, while ordinary Chat messages have their own limits. The checkout text says all of ChatGPT, which would bring Chat into the same pool as Codex.
This is an unconfirmed finding. OpenAI has not announced the change, and the text gives no date beyond December and no details on how the allowance would be divided. A write up citing forum users says the notice appears behind a feature flag that is off by default, so most people may not see it yet. Blaho suggested it could be linked to OpenAI's plan to combine Chat and Work features, but that is his inference.
The finding landed on the same day OpenAI doubled usage limits on Pro and Business Premium plans, a separate story in this deck.
What to expect next
Watch for OpenAI to confirm or deny the change, and for the help article behind the Learn more link to go live with the actual allocation rules. Key details include whether limits grow to cover both products, whether credits can top up the shared pool, and whether all plans are affected. User reaction from heavy Codex users will likely shape how OpenAI words any final announcement.
