Microsoft introduces an A.I. chatbot for cybersecurity experts

Microsoft on Tuesday announced a chatbot designed to help cybersecurity professionals understand critical issues and find ways to fix them. The company has been busy bolstering its software with artificial intelligence models from startup OpenAI after OpenAI's ChatGPT bot captured the public imagination following its November debut. The resulting generative AI software can at times be "usefully wrong," as Microsoft put it earlier this month when talking up new features in Word and other productivity apps. But Microsoft is proceeding nevertheless, as it seeks to keep growing a cybersecurity business that fetched more than $20 billion in 2022 revenue. The Microsoft Security Copilot draws on GPT-4, the latest large language model from OpenAI -- in which Microsoft has invested billions -- and a security-specific model Microsoft built using daily activity data it gathers.
