+# Multimodal RAG with Nemotron Embed and Rerank VL Models
+
+Search for recipes using input queries of text or images.
+
+Dataset is 10,000 recipes from [Food.com](https://www.kaggle.com/datasets/shuyangli94/food-com-recipes-and-user-interactions) turned into images and markdown and embedded into the same feature space.
+
+Options: 
+
+* Default is to retrieve most similar recipes via visual or text search
+* Optional: Rerank initial results with reranker model (note: this increases latency)
+* Optional: Generate a summary of the returned recipes (note: this increases latency)
+
+Details:
+
+* **Dataset used:** https://huggingface.co/datasets/mrdbourke/recipe-synthetic-images-10k
+* **Embedding model used:** https://huggingface.co/nvidia/llama-nemotron-embed-vl-1b-v2
+    * **Note:** By default we use the image + text embeddings as we have access to image and text pairs in our dataset, and according to the [launch blog post](https://huggingface.co/blog/nvidia/llama-nemotron-vl-1b), these work the best.
+* **Rerank model used:** https://huggingface.co/nvidia/llama-nemotron-rerank-vl-1b-v2
+* **Generation model used:** https://huggingface.co/Qwen/Qwen3-VL-2B-Instruct (note: you could use a larger model such as [Nemotron v3](https://huggingface.co/collections/nvidia/nvidia-nemotron-v3), however, this will require more compute resources)
+
+**Note:** This README.md was authored in a [live tutorial recorded for YouTube](https://youtube.com/live/XWmqcFiBvpU?feature=share).

+                
+Input an image or text about food and get recipe images/text back.
+
+This is a scalable workflow that can lend itself to many use cases such as business document retrieval, technical manual look ups and more.
+
+By default it returns the top 3 results from a database of 10,000+ recipes. We've limited it to 3 for the demo but in practice you could return as many as you like.
+
+* **Dataset used:** https://huggingface.co/datasets/mrdbourke/recipe-synthetic-images-10k
+* **Embedding model used:** https://huggingface.co/nvidia/llama-nemotron-embed-vl-1b-v2
+    * **Note:** By default we use the image + text embeddings as we have access to image and text pairs in our dataset, and according to the [launch blog post](https://huggingface.co/blog/nvidia/llama-nemotron-vl-1b), these work the best.
+* **Rerank model used:** https://huggingface.co/nvidia/llama-nemotron-rerank-vl-1b-v2
+* **Generation model used:** https://huggingface.co/Qwen/Qwen3-VL-2B-Instruct (note: you could use a larger model such as [Nemotron v3](https://huggingface.co/collections/nvidia/nvidia-nemotron-v3), however, this will require more compute resources)
