Microsoft has announced the removal of all usage limits on Copilot’s voice capabilities and Think Deeper, powered by OpenAI’s o1 reasoning model. This expansion follows Microsoft’s earlier decision to make the o1 model available to all Copilot users last month, and now, users can enjoy unlimited access to these AI-driven features.
The decision comes against the backdrop of fierce competition in the AI industry, where rival companies are aggressively rolling out advanced AI models for free. Deepseek and Elon Musk’s xAI, Grok, have both introduced enhanced versions of their models, while Anthropic has also released its latest version, further intensifying the fight for AI dominance.
These developments have put OpenAI under immense pressure, as its profitability and long-term sustainability continue to be scrutinized, especially in light of legal challenges from Musk, who accuses OpenAI of abandoning its original not-for-profit mission.

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’s latest move is widely seen as a strategic response to growing competition, and Microsoft aims to retain users and fend off competitors, who are also expanding free access to AI.
“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.
However, they also warned that demand surges and security concerns might cause occasional interruptions. “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 team added.
While Microsoft is making these features free, the company is not abandoning its paid model. It is continuing to sell its $20-per-month Copilot Pro subscription, which offers several advantages:
- Preferred access to the latest AI models during peak times
- Early access to experimental AI features (with Microsoft hinting at more developments soon)
- Additional use of Copilot in select Microsoft 365 apps, such as Word, Excel, and PowerPoint
OpenAI’s Profitability Under Scrutiny as Competition Heats Up
The decision to remove restrictions on free AI access is not just about expanding user engagement—it also reflects OpenAI’s mounting challenges. Microsoft is heavily invested in OpenAI, but as competition intensifies, OpenAI’s ability to generate sustainable revenue is being questioned.
OpenAI, which started as a not-for-profit AI research organization, has faced criticism for pivoting toward commercialization. One of its staunchest critics is none other than Elon Musk, who was one of OpenAI’s original co-founders. Musk has filed a lawsuit against OpenAI, alleging that the company has deviated from its original mission of making AI freely available for the benefit of humanity. Instead, Musk claims OpenAI is now pursuing profit-driven interests under Microsoft’s influence.
However, Microsoft’s decision to offer unlimited access to AI tools is believed to be a clear attempt to protect its market position. The AI industry is evolving rapidly, and companies are racing to acquire users before fully transitioning to monetization models.
