You could point it at a messy spreadsheet and watch it clean, analyze, and chart the data across Excel, a browser, and a presentation deck without stopping to ask permission at each step. OpenAI says it tops benchmarks for real-world tasks like navigating websites and operating software. If this works reliably, your AI assistant just graduated...
