On Thursday, Microsoft made one of ChatGPT's most impressive features free for all, releasing a new "Think Deeper" mode for Copilot, powered by OpenAI's o1 reasoning model.

Microsoft is adding OpenAI’s o1 model to its Copilot AI experience as a feature called Think Deeper. It is available for free to all users with a Microsoft account.

Both Microsoft Copilot and ChatGPT offer compelling AI capabilities. But how do their Windows apps fare against each other? Let's break down the experience of both apps on Windows 11. Microsoft wants Windows to evolve into an AI-powered operating system—with Copilot as the bedrock of the AI-powered experiences.

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.

Microsoft has provided unlimited free access to OpenAI's o1 model, which was released in December and can be as much as $200/month.

OpenAI's o1 reasoning model usually requires a costly subscription, but it's now free to all Microsoft Copilot users. This move follows a surge in popularity for Chinese AI app Deepseek and its free reasoning model earlier this week.
