OpenAI overhauls ChatGPT's model selection

Summary

OpenAI has revamped ChatGPT's model selection interface, introducing a tiered system for users based on their subscription. Users now see "Instant" for quick responses, "Thinking" for complex tasks, and "Pro" for the most powerful models. A dropdown menu allows selection of specific model versions, including "Latest" (currently 5.4), 5.2, 5.0, or o3. More granular settings under "Configure" enable the old Auto function, which automatically switches between Instant and Thinking modes. OpenAI also simplified the repeat menu under Answers, added a "Nerdy" personality style, and is rolling out GPT-5.4 mini while improving GPT-5.3 Instant to use less sensationalized wording. This overhaul addresses previous user concerns about the routing system's opacity and model selection.

Key takeaway

For product managers overseeing AI-powered applications, this ChatGPT interface overhaul highlights the importance of transparent model selection and tiered access. Your users benefit from clear choices like "Instant" or "Thinking" modes, rather than opaque routing. Consider offering explicit model version selection and configurable auto-switching to empower users and build trust, especially when dealing with varying computational costs and performance needs.
