"## Multi-modal RAG\n",
"\n",
"Many documents contain a mixture of content types, including text and images. \n",
"\n",
"Yet, information captured in images is lost in most RAG applications.\n",
"\n",
"With the emergence of multimodal LLMs, like [GPT-4V](https://openai.com/research/gpt-4v-system-card), it is worth considering how to utilize images in RAG:\n",
"\n",
"`Option 1:` \n",
"\n",
"* Use multimodal embeddings (such as [CLIP](https://openai.com/research/clip)) to embed images and text\n",
"* Retrieve both using similarity search\n",
"* Pass raw images and text chunks to a multimodal LLM for answer synthesis \n",
"\n",
"`Option 2:` \n",
"\n",
"* Use a multimodal LLM (such as [GPT-4V](https://openai.com/research/gpt-4v-system-card), [LLaVA](https://llava.hliu.cc/), or [FUYU-8b](https://www.adept.ai/blog/fuyu-8b)) to produce text summaries from images\n",

"* We will use the [multi-vector retriever](https://python.langchain.com/docs/modules/data_connection/retrievers/multi_vector) with [Chroma](https://www.trychroma.com/) to store raw text and images along with their summaries for retrieval.\n",

"* Retrieval is performed based upon similarity to image summaries as well as text chunks.\n",
