From solo developers to enterprise engineering organizations — Codex pricing scales with your team and your ambition.
Three tiers, zero surprises — every Codex plan includes core platform access with transparent limits.
Codex pricing is built around a simple principle: you should only pay for what your team actually uses. The Starter plan gives individual developers a generous free allowance to evaluate every core capability. The Professional plan removes all limits and adds team collaboration features at a flat per-developer rate. Enterprise plans wrap everything in custom deployment options, dedicated support, and the compliance controls that regulated industries require.
Every plan includes access to the Codex CLI, the web dashboard, and community resources. Professional and Enterprise add IDE plugin support, automated code review, team analytics, and priority support channels. Annual billing saves 20% across all paid tiers. There are no per-seat minimums on Starter or Professional — you can have a team of three on Professional or a team of three hundred, and the per-developer pricing stays the same. Enterprise plans have a minimum team size of 25 developers and include custom volume pricing.

Five hundred code generations per month, full CLI access, and community support — no credit card needed.
The Codex Starter plan is the entry point for every developer curious about AI-assisted programming. You get 500 code generations each month — enough to build several full features, scaffold a new project, or explore the platform across multiple languages. The Starter plan includes the full Codex CLI with all commands. Community support is available through the Codex forum where other developers and Codex engineers answer questions daily. The Starter plan never expires, never requires payment information, and never nags you to upgrade — it exists because we believe every developer should have access to capable AI tools regardless of budget.
Unlimited generations, full IDE integration, automated code review, and team dashboards for professional engineering teams.
The Professional plan removes every limit and adds the features that teams need to ship consistently. Unlimited AI code generations mean your team never has to think about quotas. Full IDE integration puts Codex suggestions directly into VS Code, JetBrains IDEs, and Neovim — inline completions, chat-based generation, and context-aware refactoring all happen without leaving the editor. Automated code review scans every pull request and delivers a detailed report before human reviewers spend time on it. Team dashboards show velocity trends, review coverage, and adoption metrics across your engineering organization.
Priority email support guarantees a response within four business hours. The 99.5% uptime SLA ensures the platform is available when your team needs it. Annual billing at $23 per developer per month reduces the effective cost by 20%. A 14-day free trial with no credit card lets you evaluate Professional with your actual codebase and workflow before committing.
On-premise deployment, SSO integration, dedicated support, and compliance controls for organizations operating at scale.
Codex Enterprise is built for organizations with specific security, compliance, and operational requirements. On-premise deployment runs the entire Codex platform within your VPC or data center — no code ever leaves your network perimeter. SSO integration supports SAML, OIDC, and SCIM against your existing identity provider. Role-based access control enables fine-grained permissions: grant specific team members access to code generation but not review configuration, or limit deployment management to platform administrators.
Dedicated support includes a named account manager, a Slack channel with the Codex engineering team, and quarterly business reviews. The 99.9% SLA is backed by financial penalties. Audit logging captures every action for compliance reporting — SOC 2, HIPAA, and FedRAMP evidence is available in the compliance center. Enterprise plans require a minimum of 25 developers. Pricing is customized based on team size, deployment model, and feature requirements. Contact the sales team for a quote and proof-of-concept walkthrough tailored to your organization.
Save 20% with annual billing on Professional plans — Enterprise customers receive custom volume pricing.
Annual billing on the Codex Professional plan reduces the per-developer cost from $29 to $23 per month — a yearly savings of $72 per developer. Billing is processed once annually, simplifying procurement and budget planning. Invoices include detailed breakdowns for accounting and are available in the billing dashboard alongside monthly usage reports. Enterprise customers on custom contracts receive volume pricing that scales with team size — larger organizations pay progressively lower per-developer rates. Nonprofit organizations, educational institutions, and open-source maintainers may qualify for additional discounts — contact support@codex.gr.com with details about your organization to discuss eligibility.
Upgrade anytime with prorated billing — downgrade at the end of your cycle, no questions asked.
You can upgrade from Starter to Professional at any point during your billing cycle. The upgrade takes effect immediately, and your invoice is prorated for the remaining days in the cycle. Downgrades from Professional to Starter take effect at the end of the current billing period — you retain full Professional access until that date. Enterprise contracts have custom terms negotiated during onboarding. All plans can be cancelled at any time through the account dashboard. Cancelled Professional subscriptions retain access until the end of the paid period. Starter accounts that go unused for 12 months may be archived, but all project data is retained and can be reactivated by logging in.
Free forever — 500 AI code generations per month, full CLI access, web dashboard, and community forum support without a credit card.
The Starter plan is Codex without financial commitment. You get 500 code generations each month, which supports building several features or scaffolding multiple projects. The full CLI is available — every command, every flag, every integration option. The web dashboard provides project management and configuration. Community support operates through a forum where Codex engineers and other developers answer questions. Starter exists to ensure every developer, regardless of budget, can access capable AI development tools. The plan resets monthly on your account creation anniversary, and unused generations do not roll over.
$29 per developer per month or $23 with annual billing — flat rate regardless of team size, no per-seat minimums.
Professional pricing is straightforward: every developer on your team costs the same flat rate. There are no tiers within Professional, no usage-based surcharges, and no feature gates. A team of 3 pays $87 per month; a team of 30 pays $870 per month. Annual billing drops the rate to $23 per developer per month. You can add or remove developers at any time — the next invoice reflects the change automatically. Each developer gets their own Codex account with individual API keys, personal configuration, and separate usage tracking on team dashboards. The plan includes a 14-day free trial with full Professional access — no credit card is required to start the trial.
Custom pricing based on team size and requirements — includes on-premise deployment, SSO, dedicated support, audit logging, and a 99.9% SLA.
Enterprise plans are scoped individually for each organization. The base includes on-premise deployment, SAML/OIDC/SCIM identity integration, fine-grained RBAC, audit logging, and a dedicated support team with a named account manager. Additional services — such as FedRAMP package support, HIPAA BAAs, custom model fine-tuning, and extended data retention — are priced according to scope. The 99.9% SLA includes financial penalties for missed uptime targets. Enterprise contracts typically run 12 or 24 months with custom renewal terms. The sales team provides a detailed quote after understanding your security requirements, team size, and deployment preferences.
A 14-day free trial with full Professional access — no credit card, no restrictions, no automatic conversion to paid.
The Professional trial gives your entire team full access for 14 days. Unlimited code generations, all IDE plugins, automated code review, team dashboards — everything the Professional plan offers. No credit card is required to start, and the trial does not auto-convert to a paid subscription. At the end of 14 days, your account reverts to the Starter plan unless you choose to subscribe. Enterprise prospects receive a custom proof-of-concept engagement rather than a self-service trial — this typically includes a dedicated environment, onboarding support, and a structured evaluation plan.
Upgrades are immediate and prorated — downgrades take effect at the end of your current billing period with no penalties.
Switching from Starter to Professional happens instantly through the account dashboard. Your invoice is prorated for the remaining days in the cycle, so you only pay for the time you use at the Professional rate. If you decide Professional is not for you, downgrading back to Starter is equally simple — the change takes effect at your next billing date, and you retain full Professional access until then. Enterprise customers negotiate switching terms during contract onboarding. There are no early termination fees for Professional plans — you can cancel anytime and your access continues until the end of the paid period.
