OpenAI introduced new “Auto,” “Fast,” and “Thinking” settings for GPT-5 this week, contradicting its statement that would simplify the promise of “one size fits all” experience, with a sole AI model.
Now ChatGPT users can select from the model picker. The Auto setting works like GPT-5’s model router that OpenAI initially announced. However, the company is also giving users options to circumnavigate it, allowing them to access fast and slow responding AI models directly.
Sam Altman, CEO at OpenAI, made the announcement on a post on X on Tuesday.
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…

Alongside GPT-5’s new modes, 4o is back in the model picker for all paid users by default.
These paid users also now have a “Show additional models” toggle in ChatGPT web settings, which will add models like o3, 4.1, and GPT-5 Thinking mini.
4.5 is only available to Pro users, as it costs a lot of GPUs.
The deprecation of GPT-4o and other AI models in ChatGPT sparked a backlash among users who had grown attached to the AI models’ responses and personalities in ways that OpenAI had not anticipated.
In the future, Altman says the company will give users plenty of advance notice if it ever deprecates GPT-4o. “If we ever do deprecate it, we will give plenty of notice.”
