Openi announced the biggest push of older models after announcing its new GPT5 model for Chat GPT, who found that the new Generative AI Chatboat lacks the drinking of its predecessors.
Now you have more choices for pre -GPT5 models (though you have to suffer some of them) and which components of GPT5 handle your questions.
Openi is still sorting through a rocky launch of GPT5, complaining about the lack of selection of the model. The model has been expected for more than two years and has come to the fore as Anthropic and Google have released powerful new versions of their AI models this year. –
Openi plans for a model that can handle everything: GPT5 contains two different ways, one is leaning for fast and easy tasks and one aims to argue complicated people. The routing program will decide which model has handled the signal. Chat GPT is still default, but this is not your only option. Take a look at the menu here:

Selection of GPT5 models
If you want to use the latest open technology, you can choose between some different ways of GPT5. Here is a sharp roundown:
- Auto: This mode allows the switching program to decide whether your queries are handled by a light, faster language model or a larger, slow reasoning model. Open CEO Sam Altman posted on X that it would be the best fit for most people.
- Fasting: Your inquiry will go straight to the fastest, light model. Expect quick, basic answers, but you do not have a deeper research that you get from an argument model.
- Thinking: This is a reasonable model, meaning it will try to answer your question at several stages. It can use web sources and other tools, or it can go back and repeat its past steps to try to get the right answer. There are some limits about how much you can use this model (3,000 messages per week).
- Money to think: This is a light, sharp version of the thinking model. If you target the use limit on thinking, you will be stuck with semen thinking. If you enable more model options, you can access it yourself (more on it).
- Pro: The most powerful reasoning model of the fleet, it is only available to Pro users who pay $ 200 per month. (Although the Altman tampered with Plus users, who pay $ 20 a month, which is very limited questions as a taste.)
Expand the picture
If you do not qualify the legacy model in the settings, you will look like your choice.
Once again, for most users to live with auto is probably the easiest. Think about it as is automatically driving with transmission rather than manually changing gears. Certainly, people who are really in cars can prefer stick shift, but most people should probably let the machine handle it.
How to get the old model of Open A
Each person with compensation chat GPT subscription can directly access the old GPT -4O model in the same menu where you can select your taste of GPT5. After removing this model, the most noise was made by the consumers, and Altman said that if the Open has ever decided to remove it permanently, “We will give enough notice.”
But 4O is not your only choice (if you are a compensation user). You just need to know where to see. To access GPT -4.1, 4o -mini and 3O, with GPT5 thinking mini, you have to go to your settings and toggle on “show extra model”.
