Codex account / subscription
Codex is OpenAI's AI coding agent, available in the desktop app, CLI, IDE extensions and the cloud.

About this product

Codex is OpenAI's coding agent. It understands your repository and, as asked, builds features, fixes bugs, writes tests and reviews pull requests, runs code in an isolated sandbox to check the result, and hands the changes back for your approval. Since 2026 it can also operate apps on your computer, remember your coding preferences and generate interface images. Codex signs in with a ChatGPT account, and its usage is included in paid ChatGPT plans. You can use it in:

  • The ChatGPT desktop app (macOS, Windows): since the 2026 redesign, Codex sits in the same app as chat and ChatGPT Work, with a built-in browser and terminal
  • Codex CLI: change code and run commands right in your terminal
  • Editor extensions: VS Code and compatible editors such as Cursor
  • The web (chatgpt.com/codex): run tasks in parallel in the cloud, and connect GitHub to review pull requests automatically

Which plan to choose

  • Plus: includes Codex, good for everyday coding.
  • Pro 100: much higher coding usage, for developers who use Codex for long hours every day.
  • Pro 200 / Pro 500: even higher usage for heavy users running several tasks at once.
  • Business: for teams; every member can use Codex.

Prices and limits are shown in "Official membership info" at the top of this page (checked against the official site). Our new accounts and plan activations are exactly the same as for ChatGPT; one account works in both ChatGPT and Codex.

⚠️ Before you buy

Your registration mailbox may have its own risk controls that stop you from receiving verification codes, which can block sign-in. We recommend turning on ChatGPT's multi-factor authentication (MFA): it does not depend on the mailbox and reliably prevents this kind of sign-in problem.

What Codex can do for you
Watch videos · 1
Fixing · Beginner
Fix bugs and verify
Paste an error; it reproduces it in a sandbox, fixes it and runs the tests to confirm.
Building · Intermediate
Build features from a brief
From a brief to code, tests and notes, with every change listed for your review.
Parallel · Advanced
Run several tasks in the cloud
Send several independent tasks to the cloud at once, then review and merge each.
Review · Intermediate
Review pull requests
Connect GitHub and it reviews pull requests, flagging likely bugs and risks.
Computer · Advanced
Operate apps on your computer
In the desktop app it can see the screen, click and type, working alongside tools like Figma and Xcode.
Learning · Beginner
Understand code and learn new tech
Have it explain an unfamiliar project or a piece of code, or walk you through a new framework.

Getting started

  1. Install the CLI: with Node.js installed run npm install -g @openai/codex; on Windows we recommend WSL. Other install options, the desktop app and editor extensions are on the official Codex page.
  2. Sign in: run codex in your project folder, choose to sign in with ChatGPT and follow the sign-in guide above (MFA must be on first).
  3. Write project notes: put an AGENTS.md file in the repository root describing the structure, run and test commands and conventions; Codex reads it before every task.
  4. Choose permissions: let it only suggest, edit files but ask before running commands, or run fully automatically in trusted projects.
  5. Hand off to the cloud: send several tasks to run in parallel from the web or desktop app, then review each change before merging.
  6. Code review: connect GitHub and let Codex review pull requests and point out problems.

Tips

  • Describe the expected result and how to check it, e.g. "fix this error and make npm test pass".
  • Split big jobs into smaller tasks — they are easier to review.
  • Ask it to reproduce the problem and write a failing test before changing code.
  • Commit to Git before changes so you can roll back any time.
Check before buying
Codex is included in paid ChatGPT plans; limits differ by plan — compare in "Official membership info" above.
Codex requires multi-factor authentication (MFA) to be turned on first; see "Sign-in & subscription".
Accounts work in both ChatGPT and Codex, and the after-sales rules are the same as for ChatGPT; see "Delivery & support".

Skills 39

aspnet-core✓ Build, review, refactor, or architect ASP.NET Core web applications using current official guidance for .NET web development. Use when working on Blazor Web Apps, Razor Pages, MVC, Minimal APIs, controller-based Web APIs, SignalR, gRPC, middleware, dependency injection, configuration, authentication, authorization, testing, performance, deployment, or ASP.NET Core upgrades. chatgpt-apps✓ Build, scaffold, refactor, and troubleshoot ChatGPT Apps SDK applications that combine an MCP server and widget UI. Use when Codex needs to design tools, register UI resources, wire the MCP Apps bridge or ChatGPT compatibility APIs, apply Apps SDK metadata or CSP or domain settings, or produce a docs-aligned project scaffold. Prefer a docs-first workflow by invoking the openai-docs skill or OpenAI cli-creator✓ Build a composable CLI for Codex from API docs, an OpenAPI spec, existing curl examples, an SDK, a web app, an admin tool, or a local script. Use when the user wants Codex to create a command-line tool that can run from any repo, expose composable read/write commands, return stable JSON, manage auth, and pair with a companion skill. cloudflare-deploy✓ Deploy applications and infrastructure to Cloudflare using Workers, Pages, and related platform services. Use when the user asks to deploy, host, publish, or set up a project on Cloudflare. define-goal✓ Help the user define a concrete, measurable goal before starting work, especially when they ask to use the goal tool, create a goal, set an objective, clarify success criteria, or turn a fuzzy intention into a quantitative outcome. Use this skill for goal creation and goal refinement only; it does not manage durable snapshots, decision logs, or long-running execution artifacts. figma✓ Use the Figma MCP server to fetch design context, screenshots, variables, and assets from Figma, and to translate Figma nodes into production code. Trigger when a task involves Figma URLs, node IDs, design-to-code implementation, or Figma MCP setup and troubleshooting. figma-code-connect-components✓ Connects Figma design components to code components using Code Connect mapping tools. Use when user says "code connect", "connect this component to code", "map this component", "link component to code", "create code connect mapping", or wants to establish mappings between Figma designs and code implementations. For canvas writes via `use_figma`, use `figma-use`. figma-create-design-system-rules✓ Generates custom design system rules for the user's codebase. Use when user says "create design system rules", "generate rules for my project", "set up design rules", "customize design system guidelines", or wants to establish project-specific conventions for Figma-to-code workflows. Requires Figma MCP server connection. figma-create-new-file✓ Create a new blank Figma file. Use when the user wants to create a new Figma design or FigJam file, or when you need a new file before calling use_figma. Handles plan resolution via whoami if needed. Usage — /figma-create-new-file [editorType] [fileName] (e.g. /figma-create-new-file figjam My Whiteboard) figma-generate-design✓ Use this skill alongside figma-use when the task involves translating an application page, view, or multi-section layout into Figma. Triggers: 'write to Figma', 'create in Figma from code', 'push page to Figma', 'take this app/page and build it in Figma', 'create a screen', 'build a landing page in Figma', 'update the Figma screen to match code'. This is the preferred workflow skill whenever the u figma-generate-library✓ Build or update a professional-grade design system in Figma from a codebase. Use when the user wants to create variables/tokens, build component libraries, set up theming (light/dark modes), document foundations, or reconcile gaps between code and Figma. This skill teaches WHAT to build and in WHAT ORDER — it complements the `figma-use` skill which teaches HOW to call the Plugin API. Both skills s figma-implement-design✓ Translates Figma designs into production-ready application code with 1:1 visual fidelity. Use when implementing UI code from Figma files, when user mentions "implement design", "generate code", "implement component", provides Figma URLs, or asks to build components matching Figma specs. For Figma canvas writes via `use_figma`, use `figma-use`.

After-sales policy

① ChatGPT accounts come with one week of after-sales support. If the account is banned, we will replace it.

② If a Plus monthly membership loses its Plus status, we refund the remaining days: refund = price paid ÷ 30 × remaining days − ¥10 handling fee. (Example: a Plus monthly membership bought for ¥165 is banned after 7 days; the refund is 165 ÷ 30 × (30 − 7) − 10 = ¥116.50.) Note: no after-sales support if the account is banned.

③ If a Pro monthly membership loses its Pro status, we refund the remaining days: refund = price paid ÷ 30 × remaining days − ¥30 handling fee. (Example: a Pro monthly membership bought for ¥1,550 is banned after 7 days; the refund is 1550 ÷ 30 × (30 − 7) − 30 = ¥1,158.33.) Note: no after-sales support if the account is banned.

④ Team (Business) monthly memberships currently have no after-sales support.

⑤ The Cyber verification service may lead to the account being banned; our Cyber verification service comes with no warranty.
