| Microsoft has officially rolled out the most powerful model series from OpenAI to date, GPT-5.2, to web, Windows, and mobile users. As a sincere free upgrade, GPT-5.2 will coexist with the existing GPT-5.1 model in "intelligent enhancement" mode, marking the official entry of Copilot into the era of deep logical reasoning. This so-called "expert-level" model not only completes practical tasks such as building spreadsheets, writing review code, and understanding long documents faster, but also shows unprecedented maturity in handling complex tool calls and image analysis.

From a performance perspective, the leap brought by GPT-5.2 is not only reflected in speed but also in its ability to think deeply. Microsoft clearly stated that the GPT-5.2Plus version on Copilot is essentially a "thinking" variant of GPT-5.2. In a benchmark test covering 44 occupational knowledge work tasks, GPT-5.2Thinking outperformed or matched industry professionals in 70.9% of cases, while GPT-5 achieved this rate of 38.8%. This almost doubling improvement allows OpenAI to confidently position this model as a top expert for handling presentations, schedules, and various professional deliverables, setting a new industry ceiling for office automation.
In hard-core technical benchmark tests, GPT-5.2 also demonstrated its dominance. In the programming field, it set new records on SWE-Bench Pro and SWE-bench Verified, significantly surpassing GPT-5.1Thinking. In the most challenging logic and science tests, the model scored 92.4% on the GPQA Diamond test and achieved a perfect score of 100% on the AIME2025 math test.
Additionally, its significant improvements in CharXiv reasoning and ARC-AGI-2 tests confirm that Microsoft is evolving Copilot from a basic assistant into a digital intelligent entity with a rigorous logical system through technological iterations, thus maintaining a leading advantage in the fierce AI competition.
