Thomson Reuters Leverages its World-Class Data Assets to Launch Its Own Frontier Model
Thomson Reuters (TRI) launched Thomson, its proprietary large language model, trained on its proprietary content and expertise. The model was developed for $40 million, a fraction of typical frontier models' costs, and is fully controlled by the company. Thomson is initially deployed in CoCounsel Legal and will expand across legal and tax portfolios. The company aims to leverage its decades of content and expertise to build AI with high trust and accuracy standards.
