Free vs. paid plans and usage limits

Can I start free? Understanding plans and usage limits
We’ll untangle subscription fees and API costs, starting with what trips people up.

The big picture

You don’t need to pick an expensive plan right away. Try a small task first, then choose based on the features and amount of use you actually need.

First, tell four things apart

Most importantly, don’t treat a ChatGPT subscription and API billing as the same thing. First check which way you’re signed in when you work.

What plans are there?

With annual billing, the monthly price is the yearly total divided by 12. Check the actual billing cycle and commitment terms too.

Codex is included in ChatGPT plans, but which environments, models, and features you get, and how much you can use them, depend on your plan. Whether Free and Go include it, and how much, can also change as features roll out.

When using Codex, check how you’re signed in

The same Codex task can be billed differently depending on whether you use it with your ChatGPT account or with an API key.

Limits aren’t just “so many messages a day”

How long your request is, attached files, chat history, and which models and tools you use can all affect usage. One short question and one big round of changes to a project don’t use the same amount.

So this guide won’t promise “this plan gets you exactly X uses.” Go by the usage screen in your own account and the current terms.

• Tell apart “this feature isn’t available to me” from “I’ve hit my usage limit”
• Check when your limit resets and how much you have left
• Before paying for more, check what it covers and how you’ll be charged

Breaking work into small pieces and clearly giving it the files and conditions it needs also makes the results easier to review and fix.

How do I pick the right plan?

1. Write down what you want to do. Writing? Analyzing files? Building a web page?
2. Check what the free account includes. Try the feature you want on a small scale first.
3. Figure out why you’re stuck. Is the feature not supported, did you hit a limit, or is it a settings issue?
4. Compare plans that have what you need. Look beyond price at where you can use it and team management features.

If it’s for work, check your company’s approved accounts and data policies before paying for a personal plan. Team plans come with their own admin and security terms.

Prompts you can copy

Before you pay, use the prompts below to sort out what you need. Double-check any prices and features the AI suggests against the official documents.

Where people get stuck

Quick check: If I subscribe to ChatGPT Plus, are API costs from a separate program included too?

Answer: “No, the API is billed separately”
Costs from using an API key are separate from your ChatGPT subscription.
