This initiative aligns with a broader trend in the tech industry, where companies are increasingly offering advanced AI capabilities for free, particularly following the launch of DeepSeek's completely free service.

Voice Mode is designed for fast and articulate communication, making it ideal for casual conversations or language practice, rather than in-depth analysis.

While users are encouraged to explore these features, they should be aware of potential performance issues during peak usage times.

Think Deeper can handle complex queries, including generating code and explaining programming processes, although it is limited to information available up to October 2023.

This feature assists users in making significant decisions, such as evaluating home renovations or car purchases by analyzing costs and personal preferences.

Microsoft's move to offer these features for free is expected to pressure competitors who still have many AI functionalities locked behind paywalls.

Previously, these features had usage limits for free users, but the removal of these limits allows for longer interactions with the AI assistant.

This announcement, made on February 25, 2025, reflects Microsoft's strategy to enhance accessibility to AI tools and maintain competitiveness in the rapidly evolving AI landscape.

Microsoft has announced that all Copilot users will now have free unlimited access to its Voice and Think Deeper functionalities, powered by OpenAI's o1 model.

Both the Voice and Think Deeper features were initially launched in October 2024 and have now been updated to remove usage limits as of February 2025.

For those seeking priority access and additional benefits, Microsoft continues to offer a paid tier called Copilot Pro, priced at $20 per month.

Despite the unlimited access, Microsoft warns that users may experience delays or interruptions during high demand or due to security concerns.
