What is OpenAI Codex and what is it used for?
Codex is OpenAI’s tool for programming tasks. It helps with writing, explaining and checking code. At university it is mainly relevant in computer science, business informatics, statistics and data analysis, where programming tasks and evaluations come up. Which tools make sense depends on your subject. An overview is in our article on software for data science at university (in German).
Whether a tool is allowed in a course is not decided by the provider. Lecturers and examination boards decide which aids are permitted. The framework for AI tools in your studies is summarised in the overview of AI tools for students (in German).
Which offers exist for students?
OpenAI names two promotions for students that relate to Codex and ChatGPT. The table summarises OpenAI’s information. The provider’s current page always applies.
| Offer | Regular price | Student price | Duration | Verification |
|---|---|---|---|---|
| Codex credits for students | See OpenAI’s pricing page | Credits worth 100 US dollars per announcement, for the USA and Canada | See OpenAI’s help page | See OpenAI’s help page |
| ChatGPT Back-to-School (Plus) | 20 US dollars per month according to OpenAI | Four months without a fee, then 20 US dollars per month; according to OpenAI only for eligible US universities | Limited to redemption until 31 October 2026 (according to the help page) | SheerID, possibly university login or documents |
The ChatGPT information comes from OpenAI’s help page, as of October 2026. Prices are given in US dollars. The current price in euros and the regular price for Codex outside promotions are on OpenAI’s pricing page.
Does the offer apply in Germany?
The help page for the ChatGPT offer names only eligible US universities. The announcement for the Codex offer names the United States and Canada. German universities are not listed in either.
That does not mean it will never happen. OpenAI changes promotions frequently. Do not rely on forum or blog reports, but on the provider’s page you see on the day you sign up.
How do you activate the offer?
If you study at a university in a country covered by an offer, proceed in this order. The exact details are on the help page, so the steps stay general.
- Open OpenAI’s help page on Codex credits for students and read the eligibility rules. Check the country, the type of university and the end date.
- Check which proof is required. The help page states whether a university email address, a university login or a document is needed. Read the details there carefully.
- Sign in with the account you want to use the credits on, and follow the provider’s verification process.
- Note the end date of the promotion and set a reminder before it expires, so you can decide whether to keep paying.
- Before first use, check the data settings of your account. The section on data protection below explains what to look for.
What do you need to keep in mind at university?
Three points apply regardless of the offer. First, your examination regulations, your statutes and your lecturers’ instructions take priority. Many universities regulate AI use in their own guidelines, and for exams or theses additional disclosure duties often apply.
Second, do not enter personal data, interview transcripts or unpublished research data into a tool whose data use you do not fully understand. Third, check every output. Code can sound plausible and still contain errors. Our guide AI and data protection at university (in German) explains how to handle data when using AI.
What happens after your studies?
Student offers are tied to your student status or to a fixed term. When the offer ends, the provider’s standard terms apply, unless you cancel or change plan beforehand. Whether unused credits expire or can be transferred is stated in the terms and may differ.
Therefore, do not plan work processes that only function with the student offer. Check early which costs apply after the promotion ends, and whether a later employer or organisation would cover a subscription.

Does the offer apply to my university in Germany?
