This week we bring in Christian Lang, the CEO and founder of LEGA, a company that provides a secure platform for law firms and legal departments to safely implement and govern the use of large language models (LLMs) like GPT-3, Bard, and Claude. Christian talks with us about why he started LEGA, the value LEGA provides to law firms and legal departments, the challenges around security, confidentiality, and other issues as LLMs become more widely used, and how LEGA helps solve those problems.

Christian started LEGA after gaining experience working with law firms through his previous company, Reynen Court. He saw an opportunity to give law firms a way to quickly implement and test LLMs while maintaining control and governance over data and compliance. LEGA provides a sandbox environment for law firms to explore different LLMs and AI tools to find use cases. The platform handles user management, policy enforcement, and auditing to give firms visibility into how the technologies are being used.

Christian believes law firms want to use technologies like LLMs but struggle with how to do so securely and in a compliant way. LEGA allows them to get started right away without a huge investment in time or money. The platform is also flexible enough to work with any model a firm wants to use. As law firms get comfortable, LEGA will allow them to scale successful use cases across the organization.

On the challenges law firms face, Christian points to Shadow IT as people will find ways to use the technologies with or without the firm's permission. Firms need to provide good options to users or risk losing control and oversight. He also discusses the difficulty in training new lawyers as LLMs make some tasks too easy, the coming market efficiencies in legal services, and the strategic curation of knowledge that will still require human judgment.

Some potential use cases for law firms include live chatbots, document summarization, contract review, legal research, and market intelligence gathering. As models allow for more tailored data inputs, the use cases will expand further. Overall, Christian is excited for how LLMs and AI can transform the legal industry but emphasizes that strong governance and oversight are key to implementing them successfully.
