Thomson Reuters launches in-house AI model for legal work

Thomson Reuters has launched an in-house large language model called Thomson tailored for legal work. SiliconANGLE reported on Aug. 24 that the model supports tasks related to legal advice by combining Thomson Reuters legal content with external providers’ LLMs. Thomson will be applied first to CoCounsel’s table-based analysis for large-scale document review, while CoCounsel keeps a multi-model structure. Thomson Reuters said it spent about $40 million over two years and cut final training costs to about $450,000.
