When GPT-5 launched last week, OpenAI pitched it as the only AI you’ll ever need—combining the best of speed, reasoning, and creativity in a single, seamless package.
But for many users, that promise didn’t hold up. Complaints poured in about tone, accuracy, and lost capabilities from older models. On Tuesday, CEO Sam Altman effectively conceded the point, announcing that OpenAI is rolling back its all-in approach and re-opening access to a grab bag of older models.
Updates to ChatGPT:
You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people.
Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking…

The result: more power, but also more decisions to make.
Now, instead of one “brain” that adapts to you, paid users have the ability to choose between multiple models—GPT-5, GPT-4o, GPT-4.1, o3, and more—each with different strengths and quirks. On top of that, each model now comes with three “thinking modes” that change how fast (or slow) it responds: Auto, Fast, and Thinking.
Here's a cheat sheet to help you figure out which model is best for you. We've also built a game that helps you pick a model, here.
Still undecided on which model is best for you? Try our “GPT Model and Mode Picker.” It’s pretty straightforward and will take you less than 10 clicks to find your perfect AI match.
