The Only Embedding Model You Need for RAG


Summary

The video introduces a novel embedding model that is multimodal and multilingual, catering to text and code retrieval tasks. It discusses the limitations of traditional text and image embeddings in terms of information loss and storage issues. The evolution to chunk-level embeddings from token-level embeddings is explored, along with the challenges of storage and scalability. The Nvidia multimodal rag model and the Nemo Retriever model are presented, detailing their architectures, support for various tasks, and the generation of embeddings with different vector sizes. The embedding model's capabilities include processing high-resolution images, supporting single and multi-vector representations, and adjusting vector sizes for efficiency, with details provided on model weight availability, language support, and task-specific applications.
