London—Dentons, the world's largest global law firm, is to launch a proprietary version of ChatGPT that will empower its lawyers to apply generative artificial intelligence on active client matters.

"fleetAI" includes a chatbot based on OpenAI's GPT-4 Large Language Model that will enable the firm's lawyers to conduct legal research, generate legal content and identify relevant legal arguments. A second bot allows multiple legal documents to be uploaded so that key data such as clauses and obligations can be extracted, analysed and queried against.

A Dentons team led by UKIME Head of Innovation Joe Cohen has worked with Microsoft to ensure that all data uploaded into fleetAI is not used to train the model, cannot be accessed by anyone outside of Dentons and is erased after 30 days.

"The ability to upload and analyse client matter documents at speed and in a secure manner is the real game-changer - we believe Dentons will be the first law firm that has the technology to systematically incorporate generative AI into our day-to-day matter workflows", said UK, Ireland and Middle East CEO Paul Jarvis. "The use cases for fleetAI have been identified and tested with clients during the development phase and we are confident this is going to fundamentally transform the way we deliver services to them."

fleetAI, referring to the fleet-footed benefits the tool will bring to the firm's client service delivery with a nod to its London office in Fleet Place, is to launch in August 2023. In due course it will also be made available to colleagues across the global firm. Guidance will be provided to partners and staff on how to use the tool, what to use it for and risks. Users will be required to independently verify and validate all outputs and disclose to clients when interacting with fleetAI. Following the August 2023 launch there will be a 6-week beta testing period after which practice group leaders will review all feedback and produce practice-specific usage guidance.

Future versions of fleetAI are already in development. This will include integration with Dentons' existing legal robots that, for example, automate the extraction of data from Companies House and analyse clients' employment tribunal claims to predict future outcomes. Other instances under development include a knowledge chatbot, and a Business Services chatbot for internal policies. Dentons is also trialling several other third party products to ensure a portfolio approach for the firm's lawyers.
