RAG architecture should not be used for general-purpose tasks where existing models can effectively summarize or generate creative content, such as storytelling or advertising, where some level of hallucination may enhance the output. Instead, RAG is advantageous when working with custom data that requires grounding to reduce inaccuracies. For creative endeavors, relying on prompt engineering is usually more effective unless stringent alignment with specific messages or styles is needed. Customization needs are crucial in determining the appropriateness of RAG, fine-tuning, and pre-training models, making prompt engineering a recommended starting point for addressing various use cases.
Summary
In this episode we're joined by Matt Zeiler, founder and CEO of Clarifai, as he dives into the technical aspects of retrieval augmented generation (RAG). From his journey into AI at the University of Toronto to founding one of the first deep learning AI companies, Matt shares his insights on the evolution of neural networks and generative models over the last 15 years. He explains how RAG addresses issues with large language models, including data staleness and hallucinations, by providing dynamic access to information through vector databases and embedding models. Throughout the conversation, Matt and host Tobias Macy discuss everything from architectural requirements to operational considerations, as well as the practical applications of RAG in industries like intelligence, healthcare, and finance. Tune in for a comprehensive look at RAG and its future trends in AI.

- Hello and welcome to the AI Engineering Podcast, your guide to the fast-moving world of building scalable and maintainable AI systems
- Your host is Tobias Macey and today I'm interviewing Matt Zeiler, Founder & CEO of Clarifai, about the technical aspects of RAG, including the architectural requirements, edge cases, and evolutionary characteristics
Interview
- Introduction
- How did you get involved in the area of data management?
- Can you describe what RAG (Retrieval Augmented Generation) is?
- What are the contexts in which you would want to use RAG?
- What are the alternatives to RAG?
- What are the architectural/technical components that are required for production grade RAG?
- Getting a quick proof-of-concept working for RAG is fairly straightforward. What are the failures modes/edge cases that start to surface as you scale the usage and complexity?
- The first step of building the corpus for RAG is to generate the embeddings. Can you talk through the planning and design process? (e.g. model selection for embeddings, storage capacity/latency, etc.)
- How does the modality of the input/output affect this and downstream decisions? (e.g. text vs. image vs. audio, etc.)
- What are the features of a vector store that are most critical for RAG?
- The set of available generative models is expanding and changing at breakneck speed. What are the foundational aspects that you look for in selecting which model(s) to use for the output?
- Vector databases have been gaining ground for search functionality, even without generative AI. What are some of the other ways that elements of RAG can be re-purposed?
- What are the most interesting, innovative, or unexpected ways that you have seen RAG used?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on RAG?
- When is RAG the wrong choice?
- What are the main trends that you are following for RAG and its component elements going forward?
