Thomson Reuters HighQ

Today at #ILTACON2026, the largest legal technology conference globally, we launched Thomson, our first proprietary large language model, built in-house, and fully owned and controlled by Thomson Reuters. A few lines from today's announcement that stuck with us: “Thomson proves what’s possible when you build AI on decades of proprietary content and editorial expertise,” said Steve Hasker, CEO of Thomson Reuters. “That’s an advantage only Thomson Reuters has, and it shows in the results: our early evaluations put Thomson on par with the latest frontier models across a range of tasks. We’re putting it to work in CoCounsel Legal, with more capabilities and sovereign AI options to come. This is the bar we intend to keep raising.” This is Fiduciary-Grade AI™ in practice. The standard we set for AI built for professionals who cannot afford to be wrong. Thomson's first deployment is inside Tabular Analysis in CoCounsel Legal — exactly the kind of high-volume, structured document review where a purpose-built model's advantage shows up immediately. CoCounsel Legal remains multi-model by design, applying Thomson where it delivers the clearest advantage and other leading models elsewhere.
