EDRM Webinar, London: Are Large Language Models Like GPT Secure?

A Look at the Technology and the Law 

The legal industry is increasingly thinking about using AI and Large Language Models (LLMs) like GPT for document review, legal research, and even writing legal briefs. Yet, in our discussions, legal professionals regularly express concern about LLM security.

In this webinar, we discussed the following questions. Take a look at the recorded video above to hear more. 

  • Do we risk a waiver of attorney-client or work-product privileges by sending our data to OpenAI?
  • What if that data includes confidential client information?
  • Can LLMs learn from and share the information I send?
  • How do large language model providers like Microsoft assure data security and confidentiality?
  • What is the law governing these questions and how will it be applied?

Check out our article, “Are LLMs Like GPT Secure? Or Do I Risk Waiving Attorney-Client or Work-Product Privileges?”, that inspired this webinar.
