OpenAI Codex pricing changed in 2026 — and the change is the reason "codex pricing" is one of the most-searched questions about the tool. This is the plain-English breakdown: the plans, how token credits and the 5-hour window actually work, what power users really spend, and the flat-priced alternative for anyone who wants to know their bill before they build.
TL;DR: OpenAI Codex is bundled into ChatGPT plans (Plus $20, Pro $100/$200), but since April 2026 it meters usage with token credits on a rolling 5-hour window — power-user spend runs ~$100–200/month with no flat plan below Enterprise. Taskade Genesis is flat: Free, then $6/$16/$40, and it builds the whole app. Start free →
How Much Does OpenAI Codex Cost?
OpenAI Codex is included with every ChatGPT plan, metered by token-based credits. The plan tiers are Free (trial usage), Plus $20/month, Pro $100/month (5× capacity) and $200/month (20×), plus Business and Enterprise. Since April 2, 2026, what you actually get is a credit allotment that draws down on a rolling 5-hour window rather than a fixed number of messages. OpenAI's own estimate of real-world power-user spend is roughly $100–200 per developer per month.
| ChatGPT plan | Price | Codex usage |
|---|---|---|
| Free | $0 | Limited, metered credits |
| Plus | $20/mo | Larger 5-hour credit window |
| Pro (5×) | $100/mo | 5× Plus capacity |
| Pro (20×) | $200/mo | ~20× Plus capacity |
| Business / Enterprise | Custom | Workspace credits + Codex Sites |
How Codex Credits Work
Codex converts token usage into credits, drawn down on a rolling 5-hour window (not a monthly bucket). Heavier models and longer agent runs consume more; a single complex task can eat a meaningful slice of a window. Here's the mental model:
CODEX CREDIT MODEL (since Apr 2, 2026)
┌────────────────────────────────────────────────┐
│ rolling 5-hour window ──► credits refill │
│ │
│ small task ≈ a few credits │
│ typical task ≈ 5–45 credits │
│ big agent run ≈ a large slice of the window │
│ │
│ ✗ no per-task estimate shown up front │
│ ✗ no spending ceiling you set yourself │
│ ✗ no flat unlimited plan below Enterprise │
└────────────────────────────────────────────────┘
The upside: you only pay for what you use, and the included allotment is generous for light work. The trade-off: cost is variable and hard to predict, which is exactly why many teams — especially non-technical ones — prefer a flat monthly number.
Is OpenAI Codex Free?
Codex is bundled into the ChatGPT free tier, so you can try it at no cost — but free usage is limited and metered, and there's no flat unlimited plan below Enterprise. If "free" means build and publish a real app without a meter running, that's where a flat-priced builder fits better. Taskade Genesis has a genuinely usable Free plan that builds and publishes live apps, with no token metering.
Codex Pricing vs the Alternatives
How Codex stacks up against the tools people compare it to (see the full Codex alternatives breakdown):
| Tool | Entry price | Free tier | Metered? | Builds the app? |
|---|---|---|---|---|
| OpenAI Codex | Plus $20/mo | ✅ limited | ✅ token credits | Code (+ Sites on Business) |
| Cursor | Pro $20/mo | ✅ try | ✅ heavier use | Code only |
| GitHub Copilot | Pro $10/mo | ✅ usable | ✅ (as of Jun 2026) | Code only |
| Lovable | Pro $25/mo | ✅ (public) | credits | Full-stack app |
| Replit | Core $25/mo | ✅ limited | ✅ + deploy fees | App + hosting |
| Taskade Genesis | Pro $16/mo | ✅ usable Free | flat | Living app + agents |
The Flat-Pricing Alternative: Know Your Bill Before You Build
Taskade Genesis prices on a flat monthly plan — Free, then Starter $6, Pro $16, Business $40 — with no token meter and no 5-hour window. You describe a dashboard, CRM, or client portal in plain language and get a live app with AI agents, automations, and 100+ integrations. This predictability is why flat pricing matters most to the fastest-growing group of builders: non-technical operators.
Think of who actually runs a business on this: a service-business owner who replaced four spreadsheets with one app, a clinic running a gated client portal, a realtor running an inbound CRM — each on a predictable flat plan, and on Business and up, each on their own custom domain with clients logging in. A predictable bill is part of why they self-serve and stay. See the full plan matrix on the pricing page.
