With GPT-5, OpenAI has removed eight ChatGPT models all at once. You will only be able to use GPT-4o under one condition.🚨

After user complaints, Sam Altman has raised his hand allowing the choice of the "old" GPT-4o under certain conditions and for the time being.

The arrival of GPT-5 has brought an unexpected side effect for those of us who use ChatGPT in our daily lives: OpenAI has removed eight AI models in one fell swoop, GPT-4o, GPT-4.1, GPT-4.5, GPT-4.1-mini, o4-mini, o4-mini-high, o3, and o3-pro, so that all activity is directed towards GPT-5 and its versions.

And that means many changes and a lot of faith in their new model. But as the CEO of OpenAI has declared, the launch of GPT-5 was a bit more eventful than expected.

After the launch, the head of the ChatGPT company faced users in a "Ask Me Anything" on Reddit, where they expressed their dissatisfaction with the void left by the inexplicable absence of the old and (more or less) reliable models.

OpenAI takes a step back with GPT-4o but with conditions.

When OpenAI launched GPT-5, it did so promising the smartest and fastest model ever released by the company with a strategic tool under the mandate: a simplified system to choose which version is optimal for the user's request.

It should be noted that GPT-4o had not completely disappeared: it was still operational in ChatGPT's voice mode and in Apple Intelligence, although in a much more limited way.

But the migration to GPT-5 was automatic: if you had a chat in GPT-4o, 4.1, 4.5, or their mini versions, it is now operational in GPT-5. And if you were using o3, you will now continue with GPT-5 Thinking, just like those from o3-pro, which are now migrated to GPT-5 Thinking Pro.

A user reported that 'For months I was in perfect sync switching between o3, o3-pro, 4.5, and 4o, depending on the task. I knew exactly what each model could offer. Now they are gone, and I have to readjust to GPT-5'.
