-  This example is able to ingest PDFs, PowerPoint slides, Word and other documents with complex data formats including text, images, slides and tables, orchestrated with Langchain. It allows users to ask questions through a text interface and optionally with an image query, and it can respond with text and reference images, slides and tables in its response, along with source links and downloads. Refer to this [example](./multimodal-rag) for the LlamaIndex version that uses [integration](https://docs.llamaindex.ai/en/stable/examples/llm/nvidia_nim/) with NVIDIA Inference Microservices (NIMs) of the Multimodal RAG Assistant.

 This Streamlit application implements a Multimodal Retrieval-Augmented Generation (RAG) system. It processes various types of documents including text files, PDFs, PowerPoint presentations, and images. The app leverages Large Language Models and Vision Language Models to extract and index information from these documents, allowing users to query the processed data through an interactive chat interface.
 
-The system utilizes LlamaIndex for efficient indexing and retrieval of information, NVIDIA Inference Microservices (NIMs) for high-performance inference capabilities, and Milvus as a vector database for efficient storage and retrieval of embedding vectors. This combination of technologies enables the application to handle complex multimodal data, perform advanced queries, and deliver rapid, context-aware responses to user inquiries.

 ## Features
 
 - **Multi-format Document Processing**: Handles text files, PDFs, PowerPoint presentations, and images.
 - **Advanced Text Extraction**: Extracts text from PDFs and PowerPoint slides, including tables and embedded images.
-- **Image Analysis**: Uses a VLM (NeVA) to describe images and Google's DePlot for processing graphs/charts on NVIDIA Inference Microservices (NIMs).
