Thomson is Thomson Reuters' first proprietary, in-house Large Language Model, unveiled on August 24, 2026. It is based on an Open Source foundation model (reportedly Alibaba's Qwen, most recently Qwen 3.5), but has been intensively Fine-Tuned with proprietary content from Westlaw, Practical Law, Checkpoint, and Reuters, specifically targeting legal, tax, and compliance use cases. Its first commercial deployment is the Tabular Analysis feature in CoCounsel Legal for high-volume, structured document review, while CoCounsel remains a multi-model product. A smaller Open Source version is additionally made available on Hugging Face for research and non-commercial use.
