OpenAI Partner Network
What “Select Partner” means
OpenAI introduced the OpenAI Partner Network on 14 June 2026. Partners progress through three tiers: Select, Advanced and Elite. Specialisations, for example for Codex, cybersecurity and agents, are planned to follow. AURUM is a Select Partner in Europe. The tiers say nothing about your specific project, so we are happy to show you how we work. Source: OpenAI, 14 June 2026. AURUM is also an Anthropic (Claude) Partner, so we advise vendor-neutrally.
FAQ
Frequently asked questions about OpenAI, ChatGPT and Codex
What does “OpenAI Select Partner” mean?
OpenAI announced the OpenAI Partner Network on 14 June 2026. According to OpenAI, partners progress through three tiers: Select, Advanced and Elite. The tiers differ in the requirements for sales performance, technical capability, co-sell engagement and deployment experience. AURUM is a Select Partner in Europe. Ask us for project examples before you decide.
What is the difference between ChatGPT Business and ChatGPT Enterprise?
ChatGPT Business is designed for teams of 2 to 200 employees and includes ChatGPT, ChatGPT Work and Codex, plus SAML SSO, MFA and central administration. According to OpenAI, ChatGPT Enterprise adds SCIM, role-based access, central spend controls, Enterprise Key Management and, for eligible customers, data residency including Europe. Which tier fits depends on size, identity integration and data protection requirements.
How much does ChatGPT cost for companies?
According to OpenAI’s pricing page (as of 10 November 2026), ChatGPT Business costs €21 per user per month for a Standard seat and €105 for a Premium seat. In US dollars that is $20 and $100 with annual billing, or $25 and $125 billed monthly. ChatGPT Enterprise has no public price; OpenAI quotes on request. Prices and limits change often, so we re-check them before every recommendation.
Can ChatGPT be used in a company in line with GDPR?
OpenAI states that it does not use data from ChatGPT Business, ChatGPT Enterprise and the API for training by default, and it offers a data processing addendum. Eligible Enterprise and API customers can store data in Europe, and API processing can be set to Europe on supported endpoints. Whether your specific use is permitted depends on the data, the contract, the configuration and employee co-determination. We prepare this with you, but we do not provide legal advice.
What is Codex and is it worth introducing?
Codex is OpenAI’s coding agent for software development. Developers delegate tasks such as planning, changes, tests and code reviews; according to OpenAI, agents run in a sandbox and usage and spend can be controlled centrally. A small pilot with one team, clear repositories and fixed review rules shows whether it pays off. We support selection, rules and measurement.
ChatGPT or Microsoft 365 Copilot: which fits better?
Copilot is strongest when work happens in Word, Outlook, Teams and SharePoint and Microsoft 365 permissions should apply. ChatGPT suits teams that want a standalone work tool with agents, files and Codex. You can combine both. We assess your cases neutrally and say openly when Copilot or Claude fits better.
OpenAI API or Azure OpenAI?
The OpenAI API gives direct access to the models; Azure OpenAI provides OpenAI models through Microsoft Azure, today as part of Microsoft Foundry. The choice depends on contract, data location, identity and network integration and the model offering in your Azure region. Availability and model names change often, so we check the current state in the project.
May employees simply use ChatGPT privately?
Better not for company data. Private accounts lack the contract and administration features of Business or Enterprise. An AI policy, an approved solution and training prevent shadow AI. Since February 2025, Art. 4 of the EU AI Act also requires AI literacy among staff. A works council must be involved where performance or behaviour could be monitored.
