ChatGPT o1

Paste in a math question, a block of code that keeps failing, or a plan with too many moving parts, and ChatGPT o1 replies in chat with a reasoned, step-by-step answer.

ChatGPT o1 is an AI chatbot built on large language models, with two models to pick from, o1-Mini and o1-Preview, made for complex problem solving in coding, math and strategy work.

The o1 approach uses reinforcement learning to refine its thinking before it responds, which is meant to give more accurate answers on hard tasks.

Students and teachers can use ChatGPT o1 for math and other coursework.

Developers can use it as an AI code generator for software tasks.

It also handles text jobs such as creative writing, story generation and customer support replies, and it follows context, nuance and even humor across a long back-and-forth.

One caveat: if your questions are simple, you probably do not need a reasoning model.

The value shows up on multi-step problems, where working through the logic matters more than a quick reply.
