The Multimodal RAG for PDFs and Images is a generative AI project that combines Embedding generation and LLM generation with context, built with OpenAI embeddings / sentence-transformers. The project follows a clean, modular pipeline where input handling, generation, and presentation stay separated, making it easy to test, extend, and present. It showcases modern generative AI techniques while producing a working, demo-ready application.
Traditional solutions to this problem are slow, static, and unable to generate new, context-aware content on demand. Without a generative AI approach built on LLM generation with context and OpenAI embeddings / sentence-transformers, users cannot get personalized, high-quality outputs quickly, and there is no straightforward way to refine or evaluate the results.
This project applies generative AI through Embedding generation, orchestrated with OpenAI embeddings / sentence-transformers and LLM generation with context. The pipeline is designed for quality and control, with validation, evaluation, and a clean interface. It generates consistent, context-aware results and can be adapted to related tasks with minimal changes.

Evaluation of output quality
The project is layered: the input layer prepares and validates inputs through Embedding generation; the generation layer invokes the model with OpenAI embeddings / sentence-transformers and LLM generation with context; and the output layer formats and presents results via Document ingestion pipeline. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
