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.

AI can sound confident and still be wrong. For professionals acting on its answers, that matters.
At our second Trust in AI Alliance session, Thomson Reuters brought together leaders from OpenAI, Google, and AWS to ask: how do we build AI people can rely on?
Passing a lab test is easy. Staying accurate in real-world use takes continuous monitoring and improvement long after launch. That’s the standard behind Fiduciary-Grade AI™. Trust is earned, and re-earned, every day.

Succession planning isn’t just about naming the next managing partner or CEO.
It’s about whether the client trust, relationships, judgment, institutional knowledge, and leadership concentrated in a founder or key partner can outlast that person.

That’s the number one challenge for in-house counsel, according to Norie Campbell, Chief Legal Officer and Company Secretary at Thomson Reuters, whom we sat down with at #ACCAM26.
Her focus: how departments prioritize and do the most with the resources they have, and why she sees the opportunity opening up.

It brings over 120 modules of German law commentary alongside Westlaw and Practical Law Global, with citations from authoritative sources. Plans to extend it to the next generation of CoCounsel Legal are set for early 2027.

Most tax and compliance technology sit outside the systems where transactions actually happen. That's the gap Thomson Reuters and Oracle have been working to close.
Today, Thomson Reuters ONESOURCE indirect tax determination, e-invoicing, and compliance reporting solutions are listed on Oracle Cloud Marketplace and have earned Oracle Validated status for Oracle Fusion Cloud Applications.
For customers, that means a single place to find, evaluate, and activate ONESOURCE capabilities designed to work with Oracle Fusion Cloud ERP.
Together, the solutions support key parts of the indirect tax lifecycle, from tax determination and e-invoicing to compliance reporting and filing for global requirements.
The Marketplace listing builds on the solutions Thomson Reuters and Oracle introduced within Oracle Fusion Cloud ERP in June, making ONESOURCE capabilities easier to find, evaluate, and activate.

Legal work happens across many environments. The professional standard should travel with it.
Starting October 15, HighQ is available as an MCP plugin within Microsoft 365 Copilot, as a launch partner for Microsoft Copilot for Legal. That means matter context, documents, and team information from HighQ are now accessible directly in Copilot Chat and Cowork, Copilot in Teams, and Word, without switching platforms or rebuilding context.
The best integrations do not add a new tool. They make the ones legal professionals already rely on work better together.
