Codex CLI Student Discount: The $100 Credit Claim, Verified As Best We Can
OpenAI's Codex CLI itself is free to install and run — you pay through whichever ChatGPT plan (or API key) you sign in with. Several third-party sources describe a specific student credit on top of that, but we couldn't confirm it directly on OpenAI's own official page, so here's exactly what's solid and what isn't.
Quick Answer
| Item | Status |
|---|---|
| Codex CLI itself | Free, open-source software; billing happens through your ChatGPT plan |
| Reported student credit | $100 in ChatGPT credits for verified US/Canada university students, usable in Codex |
| Verification (as reported) | SheerID, one claim per student, credits valid 12 months |
| Confirmation status | Described consistently across third-party sources; not something we could verify directly on an official OpenAI page |
How Codex CLI Billing Actually Works
Codex CLI is open-source (installable via npm install -g @openai/codex or brew install --cask codex) and doesn't cost anything to run by itself. What costs money is the underlying ChatGPT plan you're signed into: Free ($0, limited), Go ($8/month), Plus ($20/month), Pro ($100/month for roughly 5x the usage), or Business ($25/user/month) — or, separately, pay-per-token API billing if you'd rather not hold a subscription at all.
About That $100 Student Credit
Multiple third-party sources describe a specific, concrete-sounding offer: verified university students in the US and Canada getting $100 in free ChatGPT credits usable in Codex, one claim per student, valid for 12 months, verified through SheerID. That level of specificity (exact dollar amount, exact verification method, exact validity period) is usually a good sign a claim is real — but we're flagging it as "reported" rather than "confirmed" because we could not locate this offer stated directly on an official openai.com page in what we checked. Treat it the same way we'd treat any third-party-only claim on this site: plausible, worth checking yourself, not something to assume is still active without seeing it in your own account.
Savings Checklist
- Check directly at OpenAI's own site for a current student credit offer before assuming the $100 figure is still accurate — offers like this can end or change without the third-party sites that describe them noticing right away.
- If you don't see a student offer, Codex CLI still works on the Free or Go tier for light usage — you don't need Plus or Pro just to try it.
- Compare token-based API billing against a flat subscription if your usage is occasional rather than daily.
- Re-verify if you're a US/Canada student specifically, since the reported offer is described as scoped to those two countries.
Compare Alternatives
For Anthropic's comparable terminal-based coding agent, see Claude Code — it has no equivalent student credit that we could find, reported or otherwise. For an IDE-integrated alternative with a more standardized verification path, see GitHub Copilot.

How We Verified This Page
Evidence checked: OpenAI Codex, ChatGPT Pricing.
Current page conclusion: Reported $100 student credit; not confirmed on OpenAI's own page. This page uses 2 official sources to separate confirmed student benefits from institution-only access, third-party verification offers, discontinued programs, and coupon claims that are not backed by current official terms.
Decision factors: eligibility, verification route, renewal or expiration rules, country or school dependency, and whether an individual student can use the offer without a school-wide contract.
Student Verification Troubleshooting & Common Pitfalls
- Use the same name, school, and country that appear on your student record. If instant verification fails, prepare a dated enrollment letter, class schedule, tuition receipt, or student ID before trying manual review.
- When access depends on your school, ask the IT desk, library, or academic technology office whether the product is already licensed before paying for an individual subscription.
- If a coupon site claims a student price but the official page does not, treat the coupon claim as unverified. Check the vendor pricing page and your logged-in checkout before entering payment details.
- Keep screenshots or notes of the official terms you used when signing up, especially price, renewal date, eligibility language, and cancellation rules.
