In September 2025, OpenAI, a company that received significant investment from Microsoft, introduced its o1-series artificial intelligence (AI) models, designed to spend more time thinking before responding. These models are capable of reasoning through complex tasks and solving more difficult problems than other leading AI models in the fields of science , programming, and mathematics.
Microsoft is helping Copilot become increasingly attractive to users.
Then in October, Microsoft launched a new Copilot feature called Think Deeper for Pro users. This feature uses OpenAI's o1 reasoning models to assist users in solving complex problems.
Earlier this year, Microsoft decided to offer Think Deeper for free to all Copilot users, although initially with usage limitations. This feature prioritizes providing in-depth, step-by-step solutions to complex queries, resulting in longer response times compared to typical Copilot interactions. Thanks to positive user feedback, Microsoft removed these limitations, allowing unlimited access to OpenAI's reasoning model.
Microsoft turns Copilot into a free gateway to ChatGPT Pro.
OpenAI recently introduced the o3-mini model, their latest and most cost-effective version. With intelligence comparable to the o1 model, the o3-mini delivers faster performance and improved efficiency. OpenAI offers the o3-mini model for free to ChatGPT users at medium settings, while paid ChatGPT subscribers can select o3-mini-high from the model selector. Notably, ChatGPT Pro subscribers (priced at $200/month) will enjoy unlimited access to both the o3-mini and o3-mini-high models.
Copilot's Think Deeper is currently the cheapest way to reach o3-mini-high.
Microsoft has now announced an enhancement to Think Deeper, which is now powered by OpenAI's latest o3-mini-high model. This means Microsoft is expanding access to reasoning models equivalent to ChatGPT Pro's capabilities to all Copilot users, but completely free of charge.
Microsoft's move aims to expand access to powerful AI reasoning tools to a wider audience. However, even with free access to advanced AI models, Copilot still faces the challenge of attracting users compared to ChatGPT, which has led the company to conduct various promotional campaigns, including within Bing.
