Microsoft makes Copilot Voice and Think Deeper free with unlimited use

Microsoft made OpenAI’s o1 reasoning model free for all Copilot users last month, and now it’s providing unlimited use of this model and Copilot’s voice capabilities to everyone. Previously, both Think Deeper (powered by o1) and Voice in Copilot had limits for free users, but Microsoft is removing these today to allow Copilot users to have extended conversations with the company’s AI assistant.

“We are working hard to scale unlimited access to advanced features to as many people as possible, as quickly as possible, starting today with Voice and Think Deeper,” says the Copilot team. “It’s worth noting you may experience delays or interruptions during periods of high demand or if we detect security concerns, misuse or other violations of the Copilot Terms.“

The unlimited use of Copilot Voice and Think Deeper comes two years after Microsoft first launched Copilot inside its Bing search engine, and just a month after the software maker revamped its Copilot Pro subscription and bundled Office AI features into Microsoft 365.

Microsoft is continuing to sell its $20 per month Copilot Pro subscription, and says users “will retain preferred access to our latest models during peak usage, early access to experimental AI features (more on that coming soon), and additional use of Copilot in select Microsoft 365 apps like Word, Excel and PowerPoint.”
