What OpenAI's own docs say about Work and Codex
If you pay for ChatGPT Plus, Pro or Business, one line in OpenAI's pricing docs is worth five minutes of your time. OpenAI's docs say ChatGPT Work and Codex share usage, and Work inside ChatGPT uses the same pricing, credits and usage limits as Codex. Put plainly, it is one bucket, not two.
So if one person on your plan runs a long Work task in the morning and a Codex job in the afternoon, both come out of the same allowance.
The difference between Chat and Work comes down to the size of the job. OpenAI describes Chat as the place for a question or a back-and-forth, and Work as the switch you turn on when you want ChatGPT to carry a larger task through to a result you can review. A quick question about a supplier email sounds like Chat. Going through a folder of invoices and writing up a summary sounds more like Work.
A workspace administrator can control access to ChatGPT Work, plugins, browser use and network access. On a small Business plan, that administrator is probably you, or whoever set up the account.
What makes the allowance run out faster
There is no single number for how far your plan goes. How many messages you get depends on the model, the size and complexity of the task, and whether it runs on your computer or in the cloud. A short question costs little, and a long task that works through many files costs more.
OpenAI's message estimates for Plus and Standard Business are counted per five-hour period. Pro plans currently have no five-hour limit, according to the same page.
Moving a task from the cloud to your own computer does not get you a second bucket. Work on your computer and work in the cloud draw from the same plan allowance, and weekly limits may apply on top.
Images are the one to watch. OpenAI says making images uses the included limits 3 to 5 times faster on average than a similar request without an image. If someone is making social posts or menu graphics all week, that is a likely place for the allowance to go.
Where to see how much is left
OpenAI suggests checking the usage dashboard every week or two to see your pace and how much is left. Put it on the calendar next to whatever else you check on a Monday. If it is Wednesday and most of the allowance is already gone, you know before a deadline instead of during one.
Connected apps have their own view. In ChatGPT, the screen Settings > Usage shows how connected apps are using your plan. That matters because app use counts toward your existing limits.
Putting a cap on connected apps
If one app is eating more than its share, you can set a ceiling on it. The steps:
- In ChatGPT, open Settings > Usage.
- Find the section called App limits.
- Open the percentage menu next to the app and pick a limit.
- Look again in a week or two and adjust the cap if the app keeps running into it.
Start with the apps you use least. They are the easiest to cap without getting in anyone's way.
What happens when you hit the limit
Running out in the middle of a job does not cut it off on the spot. If you reach the limit in the middle of a task, that turn can keep going, subject to fair use limits. It is the next request you send that runs into the wall.
You also do not have to jump to a bigger plan. Plus and Pro users who reach the limit can buy extra credits instead of upgrading. Business plans with flexible pricing can buy workspace credits.
Before you buy either, open the dashboard and see what used the allowance. If it was one app, a cap may solve it. If it was a week of image requests, cutting back may cost less than credits.
What to do
- Open the usage dashboard this week, and set a reminder to check it every week or two, the pace OpenAI suggests.
- Go to Settings > Usage in ChatGPT and see which connected apps are drawing on your plan.
- Under App limits, cap any app that does not need the full allowance, and remember the cap sets nothing aside for it.
- If you run a Business workspace, check whether ChatGPT Work, plugins, browser use and network access are turned on in your workspace, and turn off what you do not use.
- Decide now whether you would buy extra credits or wait when someone hits the limit, so nobody has to decide in the middle of a busy day.
- If you would rather have a task built once for your shop than run it by hand each week, Your Wish Is Our Code puts a written plan in front of you before a price, and the automations page explains what that covers.
