Q & A
What is the main issue with using LLMs in a medical context?
-The main issue is that LLMs often hallucinate or make up information, which is a significant problem for medical applications where reliability and accuracy are crucial.
Why has the uptake of generative LLMs in medicine been slow?
-The slow uptake is due to the inherent inaccuracy and tendency of LLMs to generate false information, which is not acceptable in the medical field.
What is the role of referenced or sourced information in the medical context?
-Referenced or sourced information is essential for doctors and medical professionals to verify the accuracy of the information and ensure it can be trusted.
What is RAG and how does it help with LLMs?
-RAG, or retrieval augmented generation, is a technique that enhances the output accuracy and reliability of LLMs by providing additional context from a database of text sources, reducing hallucinations and allowing referenced responses.
How does the RAG process work?
-RAG works by indexing a database of text sources when a user query comes in, gathering relevant sources, and feeding the top sources into the LLM, which then answers the query based on these sources.
What is the database used in the demos and what does it contain?
-The database used is a vector database containing 3000 medical genomics abstracts sourced from pharmGKB, which includes clinical guidelines for gene-drug interactions.
What is the significance of providing working PubMed links in the output?
-Working PubMed links allow doctors to verify and check the information provided by the LLM, ensuring that they can trust the source and the data's accuracy.
How does the LLM with RAG differ from the one without RAG in the first demo?
-The LLM with RAG provides more detailed content, includes more gene variants, and offers working PubMed links for verification, whereas the LLM without RAG provides less detail and lacks some gene information.
What is the second demo about and how does it utilize LLM and RAG?
-The second demo is about annotating the genome in real time using an LLM named Llama-2 70 billion, running on Groq hardware with RAG. It processes a VCF file to identify gene variants and uses the LLM to summarize relevant abstracts from the gene drug database, providing real-time, readable DNA annotations with working PubMed links.
What is VCF and why is it important in the context of the second demo?
-VCF, or variant calling format, is a text file that describes the variants of each gene a person has. It is important because it provides the sequence genome used in the second demo to identify and annotate gene variants in real time.
How do these demos illustrate the potential of LLMs in a medical setting?
-The demos show that with techniques like RAG, which improve reliability and accuracy, LLMs can be effectively utilized in a medical setting for tasks such as providing detailed genomics information and annotating genomes in real time.
What is the final message or takeaway from these demos?
-The final message is that there is a place for LLMs in the medical field, but it requires enhancing their reliability and accuracy through techniques like RAG to ensure the information provided is trustworthy and actionable for medical professionals.

🧬 Introduction to Medical Demos with LLMs
Peter introduces the video, highlighting the importance of reliability and accuracy in medical contexts. He discusses the limitations of LLMs, such as their tendency to hallucinate or fabricate information, which poses a significant challenge in medical applications. Peter emphasizes the need for referenced and sourced information in medicine, and introduces RAG (Retrieval-Augmented Generation) as a technique to improve LLM output accuracy by leveraging a database of text sources. The video will demonstrate the use of a vector database containing medical genomics abstracts from pharmGKB, a database with clinical guidelines on gene-drug interactions, to enhance LLM responses.
🔬 RAG in Action: Genomics Database Integration
The first demo showcases the application of RAG with a genomics database connected to an LLM named Mixtral, running on Groq hardware. A query regarding gene variants associated with adjusted warfarin doses is input, and the outputs with and without RAG are compared. The RAG-enhanced output is more detailed, includes missing gene variants, and provides working PubMed links for verification, demonstrating the customization of LLMs for medical use and the benefits of RAG in providing comprehensive and verifiable information.
🧬 Real-time Genome Annotation with LLMs and RAG
In the second demo, the process of annotating the genome using an LLM is discussed. The use of Llama-2, a 70 billion parameter model running on Groq hardware with RAG, is demonstrated to annotate the genome in real time. VCF (variant calling format) files, which detail a person's gene variants, are uploaded and processed to match against a gene-drug database. The LLM summarizes relevant abstracts and provides working PubMed links, effectively making someone's DNA readable in real time. This demo illustrates the potential of LLMs in medical settings when enhanced with techniques like RAG to improve reliability and accuracy.
