Microsoft Just Did the Unthinkable with Free Copilot

Last fall, Microsoft announced its latest Copilot AI features, notably Copilot Voice and Think Deeper. Copilot Voice is a voice assistant capable of continuous interaction, while Think Deeper uses OpenAI's o1 reasoning model to provide higher-quality responses to complex questions.

Voice and Think Deeper are exciting features added to Copilot last fall.

Since last month, both of these features have been free to users, but with limited access. Now, Microsoft has gone further, saying that all Copilot users will have unlimited access to Think Deeper and Voice at no additional cost. This is a big advantage over the $20-per-month ChatGPT Plus service, which also offers access to the same features.

The Think Deeper feature, based on the o1 model, is designed to 'think before you speak', so query processing times can be as short as 30 seconds. This is especially useful for STEM-related tasks such as programming, analysis, and complex problem solving. It also supports deep consulting and planning.

While OpenAI keeps its advanced reasoning model only available to paid users, the fact that it's freely accessible in Copilot is a huge opportunity for those who want to experience it without paying.

Free Copilot users now get unlimited access to Voice and Think Deeper based on OpenAI's premium o1 model.

To use these features, users simply need to log in to Copilot with a Microsoft account. Once logged in, next to the text box users will see a 'Think Deeper' button to activate the model when answering questions.

Additionally, Copilot Voice is Microsoft's version of its AI voice assistant, simulating natural conversations with four different voices: Wave, Meadow, Grove, and Canyon. The feature is available on all platforms where users can access Copilot, including the app, standalone website, and Windows.
