On March 20, 2026, OpenAI slipped a new item into its ChatGPT release notes: Codex for Students. Verified university students in the United States and Canada can claim $100 of ChatGPT credit, and it works in exactly one place — Codex, OpenAI’s agentic coding tool. The credit lands as a 2,500-credit balance, equivalent to $100, and stays valid for 12 months after the grant date.
This is not a routine promo. In the same month, GitHub moved complimentary student access to a new “GitHub Copilot Student plan” (effective March 12), and JetBrains was running a limited-time free offer bringing Codex — powered by GPT-5 — into its own IDE assistant. Student developers have become the front line of the agentic coding tool war.
The Offer: Who Qualifies and How to Claim
Per OpenAI’s official page and the service credit terms:
- Eligibility: current students enrolled at degree-granting universities in the U.S. or Canada, residing in either country when claiming; limit one credit offer per student.
- Verification: start the flow from the claim page with your ChatGPT account and university email; the account doesn’t need to be affiliated with your school — a personal account works, but student status must still verify.
- The credit: added automatically to your ChatGPT account after verification, usable only in Codex, extending usage beyond the limits of your existing plan. These are not API credits.
- Requirements: any ChatGPT plan (Free, Go, Plus, or Pro); Codex lives inside your ChatGPT account, so there’s no separate sign-up.
- Expiry: use the credits within 12 months of the grant date; anything left after that disappears. Balances are visible on the usage page in Codex settings.
Timing: The Fight for Student Developers
Line up three events on one timeline and the signal is unmistakable. On March 12, GitHub converted Copilot’s complimentary student access into a standalone Student plan — promoting the campus market from a bundled perk to a formal product line. On March 20, OpenAI entered with hard cash, restricted to Codex spend. JetBrains, meanwhile, used a limited-time free offer to pull Codex into its IDE ecosystem. All three are chasing the same crowd: developers whose tool habits are still forming.
The competitive logic is easy to read. The autocomplete era of Copilot already proved the funnel — free during student years converts to paid after employment. In the agentic era, stickiness is even higher: workflows, project context, and muscle memory all sediment inside a single platform. Whoever owns the student owns the default for the next generation.
The Business Logic Behind Free Credits
On unit economics, $100 per head is a rounding error for OpenAI; the bet is on long-term retention once the habit forms. Three design details give away the intent. First, the credits are ChatGPT credits, not API credits — users stay inside the ChatGPT account universe rather than being channeled into the API developer ecosystem. Second, the credits explicitly “extend Codex usage beyond the limits included in your plan,” which lets students preview post-paywall capacity before they ever hit it. Third, the 12-month validity roughly matches one academic year, deliberately covering a full course cycle.
The comparison is instructive: GitHub’s Student plan leverages its existing campus verification machinery and deeper IDE integration, while OpenAI’s differentiation is novelty — pitching agentic capabilities like autonomous planning, multi-file edits, and background execution as a category students haven’t touched yet.
Practical Notes for Students and Educators
For students: claim only through official OpenAI domains (chatgpt.com and openai.com) — phishing clones of credit promotions are already circulating. Watch the balance on the usage page; agentic tools burn through credits far faster than manual chat. For educators and course designers, the more interesting question is not whether to allow these tools but how to structure assessment so the agent handles the boilerplate while fundamentals still get measured. Reading debugger output, making architecture trade-offs, and defining acceptance criteria are the skills that get more valuable, not less.
$100 won’t buy a course, but it buys a full year of habit. OpenAI has clearly done that math.
