Both models are now accessible on ChatGPT. GPT-5.1 Instant, essentially the default and most-used model, is now “warmer, more intelligent, and better at following your instructions,” according to OpenAI. Meanwhile, GPT-5.1 Thinking is an advanced reasoning model that responds faster for simple tasks and more persistently on complex ones.“We heard clearly from users that great AI should not only be smart, but also enjoyable to talk to,” OpenAI said in a blog post. “GPT-5.1 improves meaningfully on both intelligence and communication style.” The company added that both models offer a way for users to “shape ChatGPT’s tone,” allowing people to control how the chat platform responds depending on the conversation they are having. Both models were rolled out to ChatGPT Pro, Plus, Go and Busines
