Partly. ChatGPT's Free plan includes Codex in the desktop app for quick coding tasks on GPT-6 Luna, as it rolls out, and Go, at $8 a month, does the same for lightweight ones. The CLI, the editor extension, Codex on the web and cloud tasks are listed from Plus, at $20 a month. The Codex CLI is open source, and with an API key you pay API rates instead of a plan.

How much does Codex cost?

It comes with ChatGPT plans: Free at $0, Go at $8 a month, Plus at $20, and Pro at $100, $200 or $500. Business costs $25 a user a month, or $20 billed yearly for 2 users or more, and Enterprise and Edu are priced through sales. Used with an API key instead, Codex costs what its tokens cost at API rates.

What are the usage limits for Codex?

They aren't fixed counts. On Plus and a standard Business seat, OpenAI estimates about 15 to 160 local messages every five hours on GPT-6.1 Sol and 350 to 3,000 on GPT-6 Luna, and weekly limits may apply too. Local messages and cloud chats share the allowance, and cloud tasks can use more of it. Pro currently has no five-hour limit. The usage dashboard, or /status in the CLI, shows what is left.

Should I get ChatGPT Plus or Pro for Codex?

Codex works the same on both; Pro buys more of it. Plus, at $20 a month, counts use in five-hour windows, and the pricing page pitches it for a few focused coding sessions each week. Pro, at $100, $200 or $500, currently has no five-hour limit, and Pro $500 adds Ultrafast mode. On Plus you can also buy credits past the limits instead of moving up.

How much does Codex cost with an API key?

With an API key, Codex runs in the CLI, the SDK and your editor and is billed per token at OpenAI's API rates, not from a ChatGPT plan. Per million tokens in and out, GPT-6.1 Sol costs $2 and $10, GPT-6 Luna $0.10 and $0.50, and GPT-6 Astra $10 and $50. An API key leaves out the cloud features: cloud tasks, GitHub code review and Slack.

How much does Codex cost for a team?

Business costs $25 a user a month, or $20 billed yearly, for 2 users or more, with SAML single sign-on, MFA, larger cloud machines, and no training on your business data by default. A standard seat gets the same usage estimates as Plus, and the workspace can buy credits past them. Enterprise and Edu are priced through sales, with SCIM, role-based access, audit logs and data residency controls.

Can Codex host the app it builds?

Through Sites, yes: it builds and hosts websites and web apps from ChatGPT or Codex, with a database, file storage and Sign in with ChatGPT. Sites is included with eligible ChatGPT plans during its public beta, connects a domain you already own, and can take payments through a third-party processor, with the integration, refunds and taxes left to you. Otherwise, Codex writes code you deploy to the host you pick.

Do I need to know how to code to use Codex?

For Codex itself, mostly yes: it works in a codebase, reading, changing and running code while you review what it did. Sites, in ChatGPT or Codex, builds a website from a description without code. If you want an app built from a description, with its database and sign-in, Fabricate, which we make, does that too.

What happens when Fabricate credits run out?

Nothing is lost: your apps stay in your account, and apps on a paid plan stay online. You can upgrade, or wait until your credits refill next month. On Pro and Max you can also buy extra credits, which never expire: 100 for $10, 300 for $27, 600 for $51, 1,000 for $80, 2,500 for $185, 5,000 for $350 or 10,000 for $650.

How Codex's usage limits and credits work

On ChatGPT's plans, Codex isn't priced by the request. It draws on the plan's usage allowance, which local work and cloud chats share, and which ChatGPT Work, for larger tasks in ChatGPT, uses too. OpenAI gives estimates, not fixed counts: on Plus and a standard Business seat, about 15 to 160 local messages every five hours on GPT-6.1 Sol, 5 to 45 on GPT-6 Astra and 350 to 3,000 on GPT-6 Luna, and weekly limits may apply as well. Cloud tasks can use more than local messages. Pro currently has no five-hour limit.

How fast the allowance goes depends on the model, the size of the task, the context the agent holds and the speed you pick. Fast mode uses it at 2.5x the standard rate and Ultrafast, on Pro $500, at 8x, and image generation uses it 3 to 5x faster on average. Voice in the desktop app costs $0.05 a minute of the same budget. The usage dashboard shows what is left, as does /status in the CLI.

At a limit, a turn already running can finish. After that, Plus and Pro can buy ChatGPT credits and keep going without changing plan, Business and Enterprise workspaces on flexible pricing buy workspace credits, and anyone can run local chats with an API key at API rates. Credits are spent per million tokens: GPT-6.1 Sol costs 50 credits in and 250 out, GPT-6 Luna 2.5 and 12.5, and GPT-6 Astra 250 and 1,250, and what a credit costs depends on the plan. Through the API, GPT-6.1 Sol costs $2 per million tokens in and $10 out, though OpenAI notes that API prices don't measure what a plan includes.

What one app costs on Fabricate

Most of a month's credits go on changes, not the first build. Here is an example month on one app, drawn against Pro's 350 credits, and a way to price your own.

An example month: one app and 30 changes

First build: about 23
30 changes: about 267
People using the live app: Not billed
In all: Inside Pro's 350, with about 60 to spare; about 290

One exception: on Pro and Max, when your app uses AI for its visitors, answering them or reading documents they upload, each use is paid from your credits. Serving the app itself never is.

The plan price is the easy part. These four decide what a month really comes to.

Running out mid-month
- CodexAt the limit, a turn already running finishes, then Codex waits for the five-hour window or the week to reset. On Plus and Pro, ChatGPT credits keep it going without a bigger plan, and with an API key you can keep working locally at API rates.
- FabricateOn Pro and Max, extra credits start at $10 for 100 and never expire, and apps on a paid plan stay online when credits run out.
Your own domain
- CodexCodex writes the code, and the domain comes from where you deploy it. Sites, ChatGPT's hosting for what you build in ChatGPT or Codex, connects a domain you already own but doesn't register one, and custom domains aren't in Enterprise workspaces at launch.
- FabricatePro connects up to 5 domains you own and Max up to 20, with the secure padlock set up for you.
Traffic to the live app
- CodexSites is included with eligible ChatGPT plans during its public beta, and OpenAI's docs point to its help center for the limits. Deployed anywhere else, the app's traffic is billed by that host.
- FabricateNot billed. Serving your published app never touches your credits.
AI inside your app
- CodexYour app's own calls to OpenAI's models go through the OpenAI API, billed per token apart from the ChatGPT plan: GPT-6.1 Sol costs $2 per million tokens in and $10 out, and GPT-6 Luna $0.10 and $0.50.
- FabricateOn Pro and Max, each AI answer your app gives and each document it reads is paid from your credits, and "Where your credits went" lists them for each app.

When Codex is the better buy

If you write code, Codex is built for that work. It reads a repository, edits files, runs commands and tests, reviews pull requests on GitHub, and runs cloud tasks that keep going while your computer sleeps, from the CLI, your editor, the desktop app, the web or iOS, and the code stays in your own repository. Plus costs $5 a month less than Fabricate's Pro, and it pays for ChatGPT as well, so if you already pay for ChatGPT, Codex costs nothing more until you reach the limits.

Pro, at $100 to $500 a month, suits a full day of coding, with no five-hour limit for now, and Sites can host a site or web app you build with it on eligible plans while it is in beta. If you work in code, Codex is the better fit. We make Fabricate, so we say this part plainly.
