Yup! Nice play to get a picture of every API user's legal ID - deprecating all models that aren't locked behind submitting one. And yep, GPT-5 does require this.
We're 4 months later, a century in LLM land, and it's the opposite. Not a single other model provider asks for this, yet OpenAI has only ramped it up, now broadening it to the entirety of GPT-5 API usage.
Your organization must be verified to use the model `gpt-5`. Please go to: https://platform.openai.com/settings/organization/general and click on Verify Organization. If you just verified, it can take up to 15 minutes for access to propagate.
And when you click that link the "service" they use is withpersona. So it is a complete shit show.
