A Champion of Generative AI Innovation, Chicago-Kent’s Daniel Martin Katz Stands Out for Guiding Legal Teams on How to Use the Latest Tools

When Daniel Katz, a law professor at Illinois Tech’s Chicago-Kent College of Law, set out to challenge the abilities of Microsoft-backed OpenAI’s GPT-4, he knew his team had to choose a task that would capture the attention of lawyers. What could be better than the bar exam? “If I picked a very narrow area of law, people wouldn’t get their head around it,” he says. In March, it emerged that the AI model passed the test, scoring in the 90th percentile.

Many Law Firms Remain Skittish About Adopting AI, Says Professor Daniel Martin Katz

When market pioneer ChatGPT first became available, many prospective users of legal generative AI tech — law firms and in-house legal departments — suffered from “Fomo”, or fear of missing out, according to Dan Katz, a professor at Chicago Kent College of Law, who leads the school’s legal tech centre. But that early enthusiasm has given way to “Fud” — fear, uncertainty and doubt — he says.
