Microsoft 365 Copilot

Microsoft has launched a redesigned version of Microsoft 365 Copilot, featuring a cleaner interface that loads twice as fast. The update includes structured responses, a 'progressive disclosure' feature for context-aware tools, and direct text formatting within the prompt box.

Microsoft researchers found that AI models introduce errors in long workflows, contradicting their potential use for automated tasks. The study tested large language models on multistep tasks and found substantial errors, with an average degradation of 50% across all models. This raises concerns about the reliability of AI agents for complex tasks.
