Thomson Reuters Launches ‘CoCounsel 2.0’ As Legal GenAI War Grows

Thomson Reuters has now fired off its latest salvo in the legal genAI war with the launch of CoCounsel 2.0, the new version of its genAI assistant. It will also tap Google’s Gemini LLM.

They’ve also taken a different strategic pitch to rival LexisNexis by placing the focus on genAI acting as additional support.

As they explain: ‘Functioning as an extra team member, [CoCo 2.0] draws on its robust set of specialized skills to handle complex, multi-step work, helping professionals quickly pinpoint key knowledge in vast databases, thoroughly communicate sophisticated information, and complete essential work with unprecedented speed.’

They’ve also stressed they are using multiple LLMs to get the best results, which is perhaps a tacit reference to the demands for high levels of accuracy with genAI tools.

David Wong, chief product officer for Thomson Reuters said: ‘CoCounsel 2.0 is founded upon our ability to combine our data, expertise, and trusted content with cutting edge technology. Partnering with leading LLM providers is a key part of our strategy and will help us deliver even more for our customers, enabling them to accomplish what they need to evolve their businesses more quickly and more effectively than ever.’

The next-gen GenAI assistant, CoCounsel 2.0, will, they said:

  • Work three times faster than the first generation of CoCounsel, generating answers in seconds, not minutes.
  • CoCounsel 2.0 will have the capability to thoroughly compare documents, delivering point-by-point results in an easy-to-navigate table with citation to sources. Customers can choose multiple documents for CoCounsel to examine and the characteristics or types of information to compare.
  • They will offer CoCounsel High Throughput Beta, for teams needing to automate the review of hundreds of thousands or even millions of documents, with human- level accuracy. This capability has been successfully deployed on an as-needed basis and will now be available to all CoCounsel users
  • Operate more intuitively, with a better understanding of the ways customers naturally communicate, and improved ability to make sense of documents.
  • Deliver more thorough, nuanced results, because it will be able to consider the full context and history of more difficult, sophisticated requests.
  • Be accessible from within Thomson Reuters products, beginning with Westlaw Precision and Practical Law.
  • Be accessible from within Microsoft 365, beginning with Word, Teams, and Outlook.
  • Be able to access customer documents directly, through server-to-server integrations with data storage solutions iManage, NetDocuments, and SharePoint.
  • And CoCounsel Drafting, the new, end-to-end GenAI-enabled solution from Thomson Reuters, is also part of it.

In CoCounsel 2.0, Thomson Reuters is adding Google Gemini 1.5 Pro to its production models suite. This updated models suite allows CoCounsel to take advantage of a substantially longer ‘context window’, unlocking new capabilities, increasing processing throughput, and improving the ability of CoCounsel to analyze complex patterns in legal documents, they said. Testing shows that a blend of multiple LLMs to power CoCounsel 2.0 delivers optimal accuracy and user experience, they added.

So, there you go. A different take to Lexis, which has gone with the personalization message, and in this case one that TR hopes will also win hearts and minds.
