Microsoft Announces Free Access to OpenAI o1 Inference Model for Copilot Users

2025-01-31

In a tweet posted on the X platform yesterday, Mustafa Suleyman, CEO of Microsoft AI, unveiled a significant decision: all users of Microsoft Copilot can now access OpenAI's o1 inference model for free. This move signifies that the Think Deeper feature, previously exclusive to paid Copilot Pro users, is now available to everyone.

Suleyman emphasized the broad impact of this rollout in his tweet: "Today, we have made the Think Deeper feature freely accessible to all Copilot users. Now, anyone can experience the convenience and efficiency brought by OpenAI's o1 inference model within Copilot."

He also revealed Microsoft's further expansion plans in the AI sector: "We are preparing several projects and look forward to sharing more surprises with everyone."

It was reported that the Think Deeper feature first debuted in October 2024 in Copilot Labs, Microsoft's experimental environment for testing AI functionalities. This feature leverages OpenAI's o1 model, focusing on chain-of-thought reasoning, aiming to provide users with deeper and more accurate responses.

Unlike traditional AI's quick and superficial replies, the Think Deeper function processes complex queries through multiple steps, generating answers with stronger structure and more consistent logic. Users only need to click the "Think Deeper" button in Copilot, and the AI will analyze the question within about 30 seconds and deliver a well-reasoned response.

Suleyman also shared practical application cases of the Think Deeper function, such as formulating detailed project plans and conducting in-depth research on various topics. These examples fully demonstrate the tremendous potential of this function in improving work efficiency and accuracy.

This free availability of the Think Deeper function undoubtedly enhances Copilot's competitiveness and offers users a superior AI experience. We look forward to Microsoft continuing its dedication in the AI field, bringing us more innovations and breakthroughs.
