Microsoft is preparing to launch GPT-5, the next iteration of OpenAI's flagship language model, by integrating it into its Copilot software with a new feature called Smart Mode. This mode allows Copilot to dynamically switch between providing fast responses and engaging in deeper reasoning, enhancing user interaction based on query complexity. The Smart Mode powered by GPT-5 has been spotted in internal testing and is currently rolling out to some users. Reports indicate that the GPT-5 release may have been delayed to perfect this functionality. The update will apply to both consumer and Microsoft 365 versions of Copilot, signaling a significant advancement in AI-assisted productivity tools.
