summary: OpenAI requires organization verification before developers can access the o3 and o4 mini models. Individuals may complete verification using a national ID through the OpenAI platform’s organization settings, where a verified status appears after approval. The post notes that model access may not immediately show in the models listing, but verified users can begin using o3 and o4 mini through the completion API.
