Note: This is the first installment in a series examining how Am Law 100 firms are using generative artificial intelligence, based on a reporting project in which our team reached out to every firm in the grouping. Part two covers the policies and guidelines law firms have put in place to govern use of generative AI for law firm professionals. Part three examines how law firms have balanced internal tool development versus purchasing tools from third-party vendors.

In the aftermath of the infamous case of a New York lawyer submitting a ChatGPT-generated legal brief with fake citations, many law firms prohibited access to public generative AI platforms. David Cunningham, chief innovation officer at Reed Smith, said the lawyer played a dual role in the profession’s adoption of generative AI—by exacerbating hesitancy and raising awareness of AI’s risks at the same time.
