Thomson Reuters’ CoCounsel redefines legal AI with OpenAI’s o1-mini model

Nov 25, 2024 - venturebeat.com
Thomson Reuters has begun testing a custom version of OpenAI’s newest language model, o1-mini, in its CoCounsel legal assistant, marking the first enterprise customization of the model. The media and technology giant is using specialized AI models from OpenAI, Google, and Anthropic, each optimized for specific legal tasks. The o1-mini model is designed for workflows that require professionals to spot minor but consequential terms and errors in legal briefs, and early testing has shown significant improvements in document review, legal research, and drafting and revision.

Thomson Reuters has also moved into AI development with the acquisition of UK-based Safe Sign Technologies, a specialist in legal-focused language models. The company's AI strategy includes developing proprietary LLMs through Safe Sign Technologies, which gives them greater control over data security, customization, and cost efficiency. This approach, combined with the use of multiple AI models, has led to a 1,400% increase in CoCounsel users over the past year and could redefine the standards for AI deployment in the legal industry.
