Current purchase and access routes

Pricing rechecked October 8, 2026: OpenAI’s pricing page now explicitly lists Pro plans at $100, $200 or $500 USD per month. That currency statement applies to Pro. The other quoted plan displays do not establish an ISO currency, universal regional availability, taxes or a checkout total. Access, security and historical statements retain the review dates stated below.

Answer first: OpenAI’s current Codex pricing page displays Free at $0/month, Go at $8/month, Plus at $20/month and Pro from $100/month. The Free, Go and Plus cards do not name an ISO currency or universal region, so Kingy preserves their dollar symbols. Pro explicitly lists $100, $200 and $500 USD monthly tiers. Business is displayed at $20 per user per month with two or more users when billed annually, or $25 per user per month when billed monthly; that card likewise does not name an ISO currency or universal region. Enterprise and Edu require sales contact.

Codex purchase routes: displayed pricing rechecked October 8, 2026; access descriptions retain their September 8 review
Route Captured display Access boundary
Free $0/month For quick coding tasks; no fixed task or message allowance is asserted here.
Go $8/month For lightweight coding tasks; availability can depend on account and region.
Plus $20/month The page explicitly lists web, CLI, IDE extension and iOS access plus cloud integrations.
Pro $100, $200 or $500 USD/month Choose the tier that fits your usage; the price does not establish a fixed number of completed tasks.
Business $20/user/month with 2+ users when billed annually; $25/user/month when billed monthly Workspace and administrative features; taxes, regional terms and total contract cost are not asserted.
Enterprise & Edu Contact sales No numeric price is published in this capture.
API key Usage-based at standard API rates Local CLI, SDK and IDE workflows; the pricing page says cloud features such as GitHub code review and Slack are unavailable on this route.

What the subscription price covers

ChatGPT Work and Codex share pricing, credits and usage limits. Running more agents or starting Work tasks uses that shared allowance. A plan’s monthly price does not promise a fixed number of completed tasks: consumption varies with the model, context, reasoning, tools, retrieval and caching.

Additional credits can extend eligible plan usage. Their purchase price and applicable discounts depend on the plan or agreement. API-key usage follows separate OpenAI Platform billing at API rates; it does not use included ChatGPT plan credits. Check the account’s current balance, limits and billing terms before starting recurring or parallel work. This review did not buy credits, run a paid task or verify a billing charge.

The sign-in method changes what is available

The authentication guide separates ChatGPT subscription access from API-key usage-based access. The desktop app, CLI and IDE extension support both for local work, while Codex cloud requires ChatGPT sign-in. API-key usage is billed through the OpenAI Platform and follows API organization controls instead of ChatGPT workspace controls.

The CLI guide documents local repository inspection, edits, installed tools and codex exec automation. The IDE guide documents VS Code and compatible editors, plus separate Xcode and JetBrains integrations. The cloud guide documents isolated environments, repository selection and review before opening a pull request.

Treat permissions as a setup decision

OpenAI’s sandbox guide separates the technical sandbox from the approval policy. Local workspace-write can edit within the approved workspace and run routine commands; broader filesystem or network actions depend on the configured boundary and approval flow. Full access removes those sandbox restrictions. Review the active profile, repository scope, network access and credentials before assigning work.

Kingy has not purchased a plan, signed in, connected a repository, submitted code, run Codex, compared model output, measured task success, audited security or verified a billing charge for this update. The pricing, access and control statements above are first-party documentation claims, not hands-on results.

What remains unknown

  • Only Pro has an explicitly stated USD currency in the retained pricing capture. No currency is inferred for the other quoted displays; region-wide availability, a tax-inclusive total and negotiated Enterprise/Edu prices remain unconfirmed.
  • No fixed task, token or message allowance is asserted; OpenAI says usage depends on model, task size, local or cloud execution, context, reasoning, tools, retrieval and caching.
  • Temporary referral offers and current usage estimates are omitted because they are not durable plan entitlements.
  • No benchmark, code-quality score, security certification, market-share claim or recommendation is asserted.

Update sources and freshness

For the October 8 pricing recheck, Kingy compared retained HTTP 200 responses from the official pricing page and its Markdown response, captured at 05:36 UTC. Both explicitly list the three Pro tiers in USD. This body correction does not turn the other dollar displays into normalized currency amounts or establish a regional checkout total. The earlier September 20 pricing assessment remains historical evidence.

Kingy retained exact first-party Markdown responses and HTTP headers for pricing, authentication, CLI, IDE, cloud and sandboxing between 00:38:13 and 00:38:28 UTC on September 8, 2026. Any change to a bound price, plan name, access route or control statement requires a new source comparison and independent editorial review before publication.

Retained June 29 editorial note

Historical disclosure: The following June 29, 2026 text is retained unchanged as earlier editorial opinion. Its superlative comparisons and alternatives were not re-tested for this purchase-and-access update and should not be read as the current sourced comparison.

Codex is OpenAI’s software-engineering agent for working on coding tasks in isolated cloud environments and developer workflows.

Kingy AI Take

Codex matters because it moves OpenAI from coding assistance toward delegated software work. The strongest use case is not asking for a snippet; it is assigning bounded engineering tasks, reviewing the resulting diff, and using the agent to accelerate maintenance, tests, bug fixes, and implementation chores.

Best Use Cases

  • Delegating small-to-medium code changes with clear acceptance criteria.
  • Generating tests, migration notes, and implementation drafts.
  • Investigating issues across a repository before a human reviews the fix.
  • Comparing cloud-agent workflows against editor-first tools like Cursor.

Best Alternatives

Claude Code is the closest Anthropic alternative, Cursor is the strongest editor-native alternative, GitHub Copilot is the default enterprise IDE alternative, and Replit is better for browser-native app-building and hosting workflows.

What Feels Unproven

Codex still depends on clear task boundaries, repository permissions, review discipline, and the quality of test coverage around generated changes. Teams should verify current product availability, supported environments, model behavior, and security controls on OpenAI’s official Codex and developer pages before treating it as an autonomous engineering lane.
