Microsoft's Copilot Gets Smarter: GPT5.2 Excels at Math and Coding
Microsoft's AI Assistant Levels Up with GPT5.2
The digital workspace just got smarter. Microsoft has unveiled a major update to its Copilot AI assistant, bringing the powerful GPT5.2 model to web, Windows 11, and mobile users worldwide.
What's New in Smart Plus Mode?
Dubbed "Smart Plus," this upgrade focuses on delivering expert-level assistance for office tasks that traditionally required human specialists. The improvements are most noticeable when tackling complex assignments:
- Building intricate Excel models
- Designing professional PowerPoint presentations
- Conducting thorough code reviews
- Summarizing lengthy documents
The secret sauce? Microsoft enhanced what they call the "Thinking" variant model - essentially giving Copilot better reasoning abilities for extended problem-solving sessions.
Benchmark Performance That Turns Heads
The numbers tell an impressive story:
In knowledge-based job evaluations (GDPval), GPT5.2 matched or surpassed human experts in 70% of test cases - nearly double the performance of its predecessor (38.8%). Technical benchmarks were even more striking:
- Perfect score on the AIME2025 Mathematics Invitational Competition
- Significant gains in software engineering tests (SWE-Bench Pro)
- Improved accuracy across all office productivity tasks
"We're seeing capabilities that genuinely surprise us," remarked a Microsoft product manager who asked not to be named. "The model doesn't just follow instructions - it anticipates needs and suggests optimizations."
Real-World Implications
The upgrade promises to change how professionals interact with their digital tools:
- Financial analysts can build complex models faster with AI-assisted error checking
- Developers get smarter code suggestions and debugging help
- Presenters receive design recommendations tailored to their content
- Researchers benefit from more accurate document summarization
The rollout comes as workplace AI tools face increasing scrutiny about their reliability for mission-critical tasks.
Key Points:
- Microsoft's Copilot now runs on upgraded GPT5.2 architecture
- New "Smart Plus" mode specializes in complex office tasks
- Demonstrates expert-level performance in technical benchmarks
- Particularly strong in mathematics and coding applications
- Available across web, Windows 11, and mobile platforms
