Microsoft 365 Copilot Chat: Copilot Chat model selector now offers GPT-5.2
Brand Impact
Microsoft has added a new GPT-5.2 option to Copilot Chat that lets users choose between fast, quick answers or deeper, more detailed reasoning for complex questions. This more powerful AI model is better at following instructions, solving math and coding problems, and explaining things clearly. Brands whose products or services require detailed explanations, technical accuracy, or complex problem-solving—such as enterprise software, financial services, or educational tools—may see increased visibility when users opt for the "Think Deeper" mode, as the improved reasoning could surface more relevant and nuanced recommendations.
