Building on our 2024 findings, this year's report highlights notable advancements as well as persistent challenges in applying generative AI tools to legal work. Our benchmark is prepared using expert lawyer reviews (rather than automated methods) with a focus on the nuanced considerations commercial litigators, general counsel and all practising lawyers face when integrating new technologies into their work.
