Microsoft makes OpenAI’s o1 reasoning model free for all Copilot users

Microsoft is bringing OpenAI’s o1 reasoning model to all Copilot users this week. You won’t need to subscribe to a $20 monthly Copilot Pro or ChatGPT Plus plan to get it either, as Microsoft is making it free for all users of Copilot.

Think Deeper, as Microsoft calls its integration of o1, works by allowing Copilot to handle more complex questions. You can tap the Think Deeper button inside Copilot, and it will take around 30 seconds to “consider your question from all angles and perspectives.”

Microsoft first launched Think Deeper in October, providing a preview of the feature inside Copilot Labs, which lets Copilot Pro subscribers experiment with new features that Microsoft is developing. Much like ChatGPT Plus, Think Deeper will supply step-by-step answers to complex questions, so it’s good for comparing two options, creating code for apps, or planning a long road trip.

Microsoft AI CEO Mustafa Suleyman revealed that the company will now offer Think Deeper at no extra cost to all Copilot users in a LinkedIn post yesterday. “I’m genuinely so excited that our tens of millions of users are all getting this opportunity,” says Suleyman. “We’ve got so much more in the pipeline right now that I can’t wait to tell you about.”
