Today on Yannic Kilcher's channel, we delve into the murky world of AI legal research tools, courtesy of a study by Stanford and Yale researchers. Yannic, the CTO of Deep Judge, a legal tech company, sheds light on the integration of AI, particularly generative AI like GPT, into the legal domain. These tools aim to tackle legal queries using publicly available data, such as laws and case law. However, the study uncovers a troubling issue: the prevalence of "hallucinations," inaccuracies generated by language models in these systems.
Yannic doesn't hold back in criticizing the shady practices of researchers and companies in the legal tech industry. He points out the unrealistic expectations placed on AI systems in legal research, emphasizing the flawed approach of applying language models like GPT to such tasks. The study introduces "retrieval augmented generation" (RAG) as a technique to combat hallucinations by combining language models with search engines to provide more accurate responses to legal queries.
The study evaluates various AI products, including GPT-4, to assess their performance in legal research tasks. It compares the effectiveness of these systems with and without RAG, highlighting the significant improvement in accuracy when using the augmented generation technique. Yannic stresses the importance of context and reasoning in legal question answering, tasks that traditional language models struggle to handle effectively. By incorporating retrieved data from a knowledge base, RAG enhances the overall reliability of AI-generated responses in the legal field.
