Since Thomson Reuters acquired legal research company Casetext last summer, it has gradually been incorporating the startup’s headline-grabbing artificial intelligence legal assistant CoCounsel, the first legal tech tool to publicly confirm using OpenAI’s GPT-4 large language model, into its broader workflows. Previously, CoCounsel functioned essentially as a chatbot in various Thomson Reuters legal offerings, and has also been offered as a stand-alone product called CoCounsel Core, available without a Westlaw subscription. 

On Wednesday, Thomson Reuters announced that it is now not only further expanding the legal capabilities of CoCounsel again, but also expanding the reach of the generative AI assistant beyond legal “to every professional it serves,” according to a news release. This includes applying CoCounsel to the company’s tax, risk, fraud and media verticals.
