Microsoft has announced that users of its Copilot AI assistant will now have free unlimited access to the Voice feature and the Think Deeper function, powered by OpenAI’s o1 model. This update, made on February 25, 2025, extends functionality to users who can now engage in conversations and tackle complex queries without limitations.
Microsoft’s Copilot AI now offers free unlimited Voice and Think Deeper features
The Voice feature was introduced in October 2024, allowing users to converse with the AI assistant. Think Deeper enhances this experience by parsing complicated queries, helping users evaluate the pros and cons of significant decisions, such as home purchases, based on cost and long-term value. Mustafa Suleyman, head of Microsoft AI, previously stated that access to the o1 model would be available to all Copilot users at no cost as of early February.
Users can access Copilot via the Copilot app on Windows or the website copilot.microsoft.com, requiring a Microsoft account for sign-in. The Think Deeper feature allows for in-depth research and analysis by providing thoughtful responses after a brief processing period. Microsoft initially faced some access limitations during the rollout of Think Deeper, but these restrictions have now been lifted, granting users full access to both Voice and Think Deeper features.
The Think Deeper functionality excels at evergreen research, handling complex topics such as the analysis of historical events or aiding in software development tasks. For example, when asked to write a basic Windows application for drawing a maze based on a user’s name, Think Deeper effectively generated detailed guidance and custom C# source files. Microsoft has not indicated plans to charge for Think Deeper, whether through direct payment or a subscription model.
During times of high demand, users may still experience delays, while Copilot Pro subscribers will retain preferred access to the latest AI models, as well as early access to experimental features. The blog post from Microsoft highlighted the benefits of the Voice and Think Deeper tools, noting their potential for users to practice languages, conduct mock interviews, and receive advice for significant purchases or renovations.
In addition to the free offerings, OpenAI has launched the o3 model, which introduces a “private chain of thought” for generating complex answers, improving performance on tasks such as software engineering challenges. However, there is no indication that access to o3 will be free.
