Thomson Reuters unveiled Thomson, a proprietary large language model trained exclusively on legal, tax, and compliance content from Westlaw, Practical Law, Checkpoint, and Reuters. The model powers CoCounsel Legal's new Tabular Analysis feature, which can review up to 10,000 documents against 100 questions while keeping user data private through Thomson Reuters' 'Fiduciary-Grade AI' architecture.

  • Tabular Analysis feature can review up to 10,000 documents against 100 questions
  • Model keeps customer data private and never uses it for model training
  • Deployed within CoCounsel Legal as part of multi-model architecture where Thomson handles domain-specific accuracy tasks
