Microsoft has just (11th Dec) started rolling out OpenAI’s GPT‑5.2 across Microsoft 365 Copilot and Copilot Studio, marking another significant leap in AI-powered productivity.
The differences between GPT5 and GPT5.2 provide “a significant upgrade in performance across various metrics”. For example, GPT-5.2 has achieved higher scores on benchmarks like ARC-AGI2 and GPQA Diamond which indicate improved abstract reasoning and scientific knowledge. In coding tasks, GPT-5.2 outperformed GPT 5.0 and 5.1 in accuracy and speed. The model also excelled on CharXiv Reasoning an AIM 2025 scores which measures LLMs capabilities in advanced mathematics and problem-solving.
The update delivers two models under one banner:
- GPT‑5.2 Thinking, ideal for deep reasoning and complex problem-solving, and
- GPT‑5.2 Instant, tailored for everyday tasks like writing, translation, and learning – all now integrated into Work IQ for actionable insights across emails, meetings, and documents.
Within Microsoft 365 Copilot, (as this rolls out), users are able to manually select GPT‑5.2 from the model menu in both Copilot Chat and Copilot Studio, enabling smarter decision-making for tasks such as: - Preparing insights ahead of meetings.
- Conducting comparisons and analysis such as market research of reviewing reports.
- Extracting strategic takeaways linked to objectives and milestones.
Microsoft has sad that Copilot Studio agents will transition automatically from GPT‑5.1 to GPT‑5.2 in early-release environments and early in 2026, the default model in Copilot Chat will shift from GPT 5 to GPT5.2
These improvements therefore deliver improvements for tasks requiring complex reasoning and problem-solving skills. How their fair in day to use will be down to you as user to evaluate and determine. For now – we get the choice to dip in and out.
This rapid launch reinforces Microsoft’s commitment to offering model choice allowing users to access the latest innovation tuned for enterprise-grade security, compliance, and performance.
