Microsoft Copilot Think Deeper: Free AI Upgrade with OpenAI’s o1 Model

Introduction

In a significant development in the field of AI-enhanced productivity tools, Microsoft has unveiled a major upgrade to its Copilot assistant service. The company announced that the “Think Deeper” feature of Microsoft Copilot is now fully powered by OpenAI’s advanced reasoning model, known as the o1 model. This upgrade is a free enhancement available to all Copilot users, marking an unprecedented move in democratizing sophisticated AI reasoning capabilities.

This article delves into the details of this announcement, providing context and background about Microsoft Copilot's AI integration, explaining the workings of the o1 model and the Think Deeper feature, and discussing the wider implications of this upgrade on users and the AI ecosystem.

Background: Microsoft Copilot and AI Integration

Microsoft Copilot is Microsoft’s AI assistant integrated deeply into Windows 11, Microsoft 365, Bing search, and multiple other productivity environments. It assists users by generating intelligent responses, automating tasks, providing career guidance, and enhancing workflow efficiency.

Originally, Microsoft Copilot leveraged different AI models for various features, with some of the more powerful AI capabilities being locked behind paid subscriptions. The “Think Deeper” feature was initially powered by OpenAI’s foundational o1 reasoning model but came with limitations, including usage rate caps and access restrictions primarily for paying customers.

With the explosion of interest and demand in AI tools, Microsoft is aggressively enhancing Copilot’s AI capabilities to offer more sophisticated assistance free of charge, aiming at widespread adoption and competitive positioning against other AI leaders.

What Is “Think Deeper” and the o1 Model?

The “Think Deeper” feature in Copilot represents a leap from simple question-answering AI towards advanced reasoning. It is designed to examine queries more thoroughly, explore multiple angles, verify initial responses, and offer alternative solutions. This results in answers that are not just accurate but contextually rich and insightful.

Technically, Think Deeper is powered by OpenAI’s o1 model, a reasoning-focused AI architecture that employs “Reasoning Tokens.” These tokens break a question down into granular parts, analyze potential scenarios, and chain together logical, multi-step thought processes. This is akin to having an AI that doesn’t just provide quick answers but acts more like an expert consultant laying out a detailed roadmap or exploring the ramifications of various solutions.

Typical use cases include:

  • Complex problem-solving (such as coding challenges and technical bottlenecks)
  • Scenario planning (exploring consequences and options)
  • Idea generation for creative projects or career strategies
  • Deep analytical tasks involving scientific, mathematical, or logical reasoning

One example noted in tests compared outputs from regular Copilot and the Think Deeper mode creating a personalized workout routine. Where regular Copilot gave a surface-level plan, Think Deeper incorporated nutrition advice, recovery tactics, and personalized progressive overload strategies, showcasing a deeper understanding of the user’s goals.

New Upgrade: Free Access for All Users

Microsoft has now made the Think Deeper feature powered by the o1 model available for free to all users of Copilot, removing prior rate limits and payment barriers. This democratization means anyone using Windows 11 or Microsoft 365 with Copilot integration can leverage advanced AI reasoning capabilities continuously without worrying about usage caps or subscription tiers.

This move is part of a broader Microsoft strategy to embed AI deeply into daily workflows while positioning itself as a leader providing “high-quality, free AI,” particularly compared to competitors who monetize advanced capabilities aggressively behind paywalls.

Technical Details and Improvements

The o1 model represents an evolution of AI reasoning from earlier generative models. It focuses on:

  • Multi-step inference: Handling complex queries that require several logical steps
  • Ambiguity recognition: Understanding when questions need further exploration or clarification
  • Contextual mapping: Linking facts and details across a query to offer cohesive responses
  • Verification and alternative solution synthesis: Ensuring reliability and depth in answers by cross-checking and proposing different approaches

Under the hood, Think Deeper’s process involves breaking down questions, running multiple reasoning passes, and stringing together output that reads like a knowledgeable dialogue rather than a simple answer snippet.

The overall experience promises faster, more precise, and insightful AI assistance within applications, Bing search, and Windows itself.

Implications and Impact

For Users

  • Enhanced Productivity: Users across professions can achieve better outcomes with AI that understands nuance and complexity.
  • Accessibility: Free access empowers students, professionals, hobbyists, and small businesses to harness advanced AI without financial barriers.
  • Smarter Decision Making: Think Deeper can support strategic planning, technical troubleshooting, and learning with expert-level advice.
  • Cross-Platform Benefits: Integration across Windows 11, Microsoft 365, and Bing delivers a unified AI experience.

For Microsoft and the AI Ecosystem

  • Competitive Edge: By embedding powerful AI reasoning for free, Microsoft challenges competitors to rethink monetization models while building its user ecosystem.
  • Ecosystem Entrenchment: Users reliant on Copilot’s AI assistance are more likely to stay within Microsoft’s productivity suite, reinforcing customer loyalty.
  • AI Democratization: This move pushes the AI industry towards more open access to sophisticated models, potentially accelerating innovation and adoption standards.

Broader AI Industry Context

Microsoft's partnership and integration with OpenAI remain vital, but Microsoft is also reportedly developing in-house AI reasoning models to supplement and potentially replace dependence on external solutions. The availability of advanced models like o1 in Copilot shows Microsoft’s commitment to leading AI integration while balancing strategic independence.

Microsoft’s approach contrasts with OpenAI’s paywalled model access, notably for advanced tiers in ChatGPT Plus and Pro subscriptions that still restrict free users. Microsoft’s free provision of such capability may intensify pressures on OpenAI’s revenue approach and shape future AI service offerings.

Conclusion

Microsoft's upgrade of Copilot’s Think Deeper feature with OpenAI’s o1 model in a free-to-use format marks a pivotal step in AI-powered productivity tools. By delivering advanced reasoning capabilities openly, Microsoft enhances its platform’s utility while setting a new bar for AI democratization in consumer and professional applications. As AI capabilities continue to expand, Microsoft positions itself as a central player in the future of intelligent work, benefiting millions with smarter, deeper AI assistance integral to Windows 11 and beyond.
