Microsoft Offers OpenAI’s Advanced o1 Reasoning Model Free for Copilot Users

The 'Think Deeper' feature enables more detailed and logical responses, but some users question the true cost of the offering.

Microsoft has made OpenAI’s o1 reasoning model available for free to all Copilot users, including those on the free tier, through the new 'Think Deeper' feature.
The o1 model employs a chain-of-thought reasoning process, breaking down complex tasks into smaller steps for improved accuracy and detailed responses.
The decision follows rising competition from DeepSeek’s R1 reasoning model, which has gained significant attention for its affordability and performance.
While Microsoft touts this as a no-cost addition, some users have noted recent increases in Microsoft 365 subscription fees, raising questions about the definition of 'free.'
The feature, accessible via a 'Think Deeper' button, does not yet support internet-based real-time information but is designed for STEM-related tasks and in-depth problem-solving.
