Microsoft has announced that it is making Copilot Voice and Think Deeper features, powered by OpenAI's o1 reasoning model, available for unlimited use to all users. This move marks a significant expansion of the company's AI capabilities, allowing users to have extended conversations with its AI assistant without any limitations.

Previously, both Think Deeper and Voice in Copilot had usage limits for free users. However, Microsoft is now removing these limits, enabling users to take full advantage of these advanced features. According to the Copilot team, "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."

It's worth noting that while unlimited access is being provided, users may still experience delays or interruptions during periods of high demand or if security concerns, misuse, or other violations of the Copilot Terms are detected. This move comes just a month after Microsoft revamped its Copilot Pro subscription and bundled Office AI features into Microsoft 365.

The unlimited use of Copilot Voice and Think Deeper is a significant development, coming two years after Microsoft first launched Copilot inside its Bing search engine. The company is continuing to sell its $20 per month Copilot Pro subscription, which offers preferred access to the latest models during peak usage, early access to experimental AI features, and additional use of Copilot in select Microsoft 365 apps like Word, Excel, and PowerPoint.

This move is likely to have significant implications for the AI industry, as it demonstrates Microsoft's commitment to making advanced AI capabilities more accessible to a wider range of users. With the removal of usage limits, users will be able to explore the full potential of Copilot Voice and Think Deeper, potentially leading to new use cases and applications.

In the broader context, this development highlights the ongoing AI arms race between tech giants, with companies like Microsoft, Google, and Amazon investing heavily in AI research and development. As AI capabilities continue to advance, we can expect to see even more innovative applications and services emerge, transforming industries and revolutionizing the way we live and work.

With Microsoft's latest move, the company is clearly signaling its intent to remain at the forefront of the AI revolution, and it will be interesting to see how this development unfolds in the coming months and years.
