Luther develops solution for internal AI language model in collaboration with Fraunhofer IAIS

Cologne, 13.06.2024 – Luther is taking another step forward in the digitalisation of the law firm world. Together with Fraunhofer IAIS, the law firm is launching an internal language model designed to protect client data.


The use of a large number of cloud-based generative language models for processing and analysing client data and information raises professional ethics concerns in Germany. Together with the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS, Luther has therefore been working hard in recent months to develop a flexible architecture for a pre-trained language model that is operated exclusively in the company environment on internal systems and is specially tailored to the needs of lawyers.

The flexible "Luther.AI" solution promises many other advantages in legal work in addition to efficiency gains, and can analyse client documents, create summaries or prepare legal assessments. The solution is currently in extended test operation, is already being used successfully in the first teams in client work and is being extended to more and more user groups.

"As a driver of innovation in the world of law firms, there was no question for us that we wanted to utilise the opportunities and benefits of generative artificial intelligence. However, as the use of large language models (LLM) in the cloud is difficult for our profession, we sought out a partnership with Fraunhofer IAIS for development. With this flexible solution, we can continue to drive forward digitalisation at Luther, while the security of our clients' sensitive data remains our top priority," says Dr Markus Sengpiel, Co-Managing Partner at Luther.

"The area of legal tech is an exciting field of application for generative AI applications. At Fraunhofer IAIS, we have been looking at the potential of AI for the industry for a long time and Luther is one of the 'first movers' when it comes to integrating technological innovations into its processes. We are delighted that our 'LLM Explore Hub' is now in use at Luther. We are implementing a language model that meets the sensitive needs of law firm operations and offers a wide range of options for automating internal law firm processes. We are convinced that our joint developments will create a high-potential basis for further innovations in the field of legal tech," says Dr Dirk Hecker, Deputy Director of Fraunhofer IAIS.
