Microsoft is now providing unlimited access to Voice and Think Deeper features for all Copilot users at no cost. The Copilot Team announced these advanced capabilities as part of their effort to build “the ultimate AI companion.” Voice allows for extended voice conversations with the AI, while Think Deeper, powered by OpenAI’s o1 model, handles complex reasoning tasks. Previously, users encountered usage limits for these features. The company suggests using Voice for language practice and mock interviews, while Think Deeper is recommended for analyzing major purchases or planning career moves. Microsoft notes that service may be affected during high demand periods or if misuse is detected. Copilot Pro subscribers will still receive preferential access during peak usage times and retain exclusive features in Microsoft 365 applications.
