Thomson Reuters\u2019 Ragunath Ramanathan, President \u2013 Legal Professionals, has announced that the \u2018next generation\u2019 of CoCounsel Legal, now available in Beta, will provide \u2018fiduciary-grade AI\u2019 and work just as well as a senior associate.<\/p>\n
\u2018The next generation of CoCounsel Legal is a unified agentic platform that plans, selects tools, retrieves authoritative content, and adapts mid-workflow just as a senior associate would, not a first-year waiting for the next instruction,\u2019 he said. <\/p>\n
Much of this is built using Anthropic\u2019s Claude Agent SDK. To get hold of these new capabilities you have to join the Beta program, which has a waitlist. The announcement slipped out in a blog post by the Thomson Reuters executive this week.<\/p>\n
They said that by building together via the Beta program \u2018we\u2019re inviting customers to help shape what CoCounsel Legal becomes\u2019.<\/p>\n
(And of course, readers will be well aware that at the same time Anthropic is moving directly into the legal sector now \u2013 although what it doesn\u2019t have is TR\u2019s huge curated legal data collection.)<\/p>\n
Sounds intriguing. So, what is on offer here? The short answer is that it\u2019s all about trust and accuracy \u2013 a topic that the recent Sullivan & Cromwell debacle has brought into sharp focus. <\/p>\n
Ramanathan states that as well as improving the reasoning capabilities of CoCounsel when it comes to the AI exploring a research task, that they have \u2018gone further to protect the integrity of that reasoning, with patent-pending tools for citation integrity and output verification\u2019.<\/p>\n
These improvements are centred on two key areas, he explained:<\/p>\n
\u2018Verification and grounding as system primitives. Authoritative retrieval, explicit source handling, and verifiable citation flows are product infrastructure \u2013 not post-processing or marketing language.<\/p>\n
Patent-pending citation integrity. Our citation ledger architecture creates a session-verifiable evidence trail for legal citations, ensuring the agent can only cite what it actually retrieved and enabling trustworthy, clickable references in output.\u2019<\/p>\n
(Note: it\u2019s not 100% clear if these two developments are already available to regular users of CoCounsel Legal, or if it\u2019s just for the new Beta program customers. AL has asked TR for more info.)<\/p>\n
And: \u2018Our leading evaluation framework encodes quality at each step. This means before any capability ships; we measure it. Licensed attorneys, including our Practical Law editors, define what the correct output looks like for each task type. <\/p>\n
\u2018Every new capability must demonstrate measurable improvement against that benchmark before it reaches production. The framework evaluates not just final outputs, but the full chain of reasoning that produced them, because an agent that arrives at the right answer through flawed reasoning cannot be trusted to do so consistently.\u2019<\/p>\n
He continues: \u2018This is fiduciary-grade AI; outputs grounded in authoritative content and customer context \u2013 making verification part of the system\u2019s architecture rather than an afterthought.\u2019<\/p>\n
\u2018In a profession where a single missed citation can cost a client their case, defensibility isn\u2019t a nice-to-have. It\u2019s the whole point. In a profession where a single missed citation can cost a client their case, defensibility isn\u2019t a nice-to-have. It\u2019s the whole point,\u2019 he concluded.<\/p>\n

Clearly accuracy is not \u2018done\u2019, there is more work needed and Thomson Reuters is focusing on that.<\/p>\n Also of note is the fact that Sullivan & Cromwell \u2013 so far, at least as understood \u2013 has not publicly named the AI tool(s) that created the hallucination that got noticed. Let\u2019s hope it was not one of the more famous legal AI \/ legal research companies..! <\/p>\n Regardless, all of this will help to push accuracy up the legal tech agenda again and the latest moves by Thomson Reuters therefore come at a good time.<\/p>\n \u2014<\/p>\n P.S. to join the Beta waitlist, get in touch with TR. They added that if you join you can expect:<\/p>\n \u2018A simpler, conversation\u2011driven experience with no tool\u2011switching or prompt engineering.
