Huh. Yesterday they said: >API deployments require different safeguards and we are working closely with partners and customers on the safety and security requirements for serving it at scale. And now this. I guess one day counts as "very soon." But I wonder what that meant for these safeguards and security requirements.

When stuff is delayed due to "safeguards" it just means they don't think they have the compute to release it right now.

Very bad habit these safeguards. These "safety" filters are counter-productive and even can be dangerous.

In my place for example, a lot of doctors are using ChatGPT both to search diagnosis and communicate with non-English speaking patients.

Even yourself, when you want to learn about one disease, about some real-world threats, some statistics, self-defense techniques, etc.

Otherwise it's like blocking Wikipedia for the reason that using that knowledge you can do harmful stuff or read things that may change your mind.

Freedom to read about things is good.

Is anyone here actually using pro models through the API? I'd be very curious what the use-case is.

Yes. High value work where cost (mostly) doesn't matter. For example, if I need to look over a legal doc for possible mistakes (part of a workflow i have), it doesn't matter (in my case) whether it costs $0.01 or $10.00, since it's a somewhat infrequent event. So i'll pay $9.99 more, even if the model is only slightly better.

Indeed, even just Terms of Service and Privacy Policy work. Infrequent enough that cost isn't an issue, but model quality absolutely is

API page lists the knowledge cutoff as Dec 01, 2025 but when prompting the model it says June 2024. Knowledge cutoff: 2024-06 Current date: 2026-04-24 You are an AI assistant accessed via an API.

Can you really believe things that the model says? (A lot of prior model api pages say knowledge cutoffs of June 2024, maybe the model picks that up?)
