NEW YORK (CONVERSEER) – Microsoft has begun rolling out the GPT 5.2 model to all web, Windows 11, and mobile Copilot users, naming it the “Smart Plus” mode.
This update is a free upgrade, launched with the new “Smart Plus” mode, and will coexist with the “Smart” mode based on GPT 5.1 released last month.
The version that Copilot comes with is explicitly defined as the “Thinking” variant of GPT 5.2, which Microsoft emphasises significantly enhances the ability to handle complex tasks.
This model enables users to complete practical tasks such as building spreadsheets, creating presentations, writing and reviewing code, understanding long documents, and processing images more quickly. It is officially defined as an “expert-level” tool capable of handling specific office tasks.

According to the GDPval assessment of “knowledge-based work” tasks for 44 occupations, GPT-5.2 Thinking outperformed or matched human industry experts in 70.9% of the test cases, while the previous GPT-5 figure was only 38.8%.
Based on multiple authoritative benchmark test results, GPT 5.2 demonstrates dominant technical strength. In the software engineering test SWE-Bench Pro, the model scored 55.6%, and in SWE-Bench Verified, it reached 80%, both figures outperforming GPT-5.1 Thinking.
Achieved a perfect score of 100% in AIME 2025 (American Mathematics Invitational), scored 92.4% in the GPQA Diamond test, scored 88.7% in the CharXiv Reasoning (with Python) test, and made significant progress in the ARC-AGI test.
