Microsoft Makes “Think Deeper” Free for All Copilot Users

[Update] February 7, 2025, 8:32 AM PT: The “Think Deeper” feature is currently only available for consumers, and commercial customers won’t be able to access it in Microsoft 365 Copilot Chat.

Microsoft is now offering its “Think Deeper” feature to all free Copilot users, removing the previous paywall. Microsoft AI CEO Mustafa Suleyman announced on LinkedIn that this tool no longer requires a Copilot Pro subscription.

What is Think Deeper?

Microsoft launched Think Deeper as an experimental feature in Copilot Labs in October. Up until now, this feature was only available for Copilot Pro subscribers, which costs $20 per month per user.

Think Deeper uses OpenAI’s o1 reasoning model to provide high-quality answers to complex questions. Microsoft highlights its effectiveness in tackling STEM-related tasks like advanced math, coding, and data analysis, while also offering detailed planning and comprehensive advice.

“The possible uses here are really infinite. I’m genuinely so excited that our tens of millions of users are all getting this opportunity. We’ve got so much more in the pipeline right now that I can’t wait to tell you about,” Suleyman explained.

How to access the Think Deeper feature in Microsoft Copilot?

Starting this week, consumers can access Think Deeper through the Copilot web app or the Copilot Android or iOS apps. To use this feature in Copilot, users will simply need to click or tap the “Think Deeper” button within the prompt bar. It will take around 30 seconds to analyze the question and generate a more comprehensive and detailed response.

Microsoft’s decision to make Think Deeper free for Copilot users follows the recent launch of DeepSeek R1, an open-source reasoning model from Chinese startup DeepSeek. Microsoft has since added DeepSeek R1 to Azure AI Foundry and GitHub, and it’s also bringing this model to Windows 11 Copilot+ PCs.
