I thought this was indeed the case at release, but then they changed it to also be for non-streaming (completions). So either they reverted it back or it was a temporary bug during the early days of the model.

When did you last check?

I ran a test just now, and gpt-5 without streaming works without the biometric check.

		Interesting! Makes one wonder why they limit streaming only. I guess to induce just enough friction then.
