In-product advance notice before model retirement

[Olesia]

GPT-5.3 disappeared today without any in-product warning — the same issue I previously raised when GPT-5.2 was removed:

@Olesia

I understand that GPT-5.2 retirement may have been mentioned in release notes earlier. But as a user, I only learned about it after the model had already disappeared — from another user in this forum thread.

I don’t think release notes alone are sufficient communication for this kind of change.

I’m saying this not only as a disappointed user, but also as a product designer: when a product supports long-running conversations and model-specific continuity, forced migration should be communicated inside the product itself — in the model picker or in existing conversations — before it happens.

Users should not have to manually track release-note timelines to avoid suddenly losing access to a model they rely on.

Even a short in-product notice 24 hours in advance would have made a major difference.

Unfortunately, today the same thing happened again — this time with GPT-5.3.

Earlier today I was still using GPT-5.3. A few hours later, it was simply gone from the model picker. No countdown, no in-product warning, no final notice in existing conversations.

What makes this especially strange is that OpenAI has already demonstrated a better approach with GPT-5.4: users were warned in advance before it was removed. So there is already a precedent for handling model retirement in a much more user-friendly way.

I understand that models are retired and products change. That is not the issue.

The issue is how the transition is communicated.

If users can build months-long conversations around a particular model, removing that model without an in-product warning breaks continuity in a way that is completely avoidable.

Release notes are documentation. They should not be the only place where users are expected to discover that a model they actively use is about to disappear.

Why wasn’t the same advance-warning approach used for GPT-5.3 that was used for GPT-5.4?

And more importantly: can in-product retirement notices become a standard part of future model migrations?

Hi @Olesia,

Thanks for sharing your detailed feedback!

I understand your concern about GPT-5.3 being removed without an advance in-product notification, especially when you're relying on a specific model for ongoing conversations.

We appreciate your suggestion to introduce advance notifications directly in ChatGPT before future model retirements. Feedback like this helps us understand how these changes affect the user experience.

While we can't confirm whether this feature will be implemented, we appreciate you taking the time to share your perspective.

We have provided advance notifications for some model transitions in the past. You can also refer to our ChatGPT Release Notes for information about model updates, retirements, and availability changes.

We understand that release notes may not fully address your request for in-product notifications, and we appreciate your feedback on making these transitions clearer.

Thanks again for your feedback!
