"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",
"* Embed and retrieve text \n",
"* Pass text chunks to an LLM for answer synthesis \n",
"\n",
"`Option 3` (Shown) \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",
"* Embed and retrieve image summaries with a reference to the raw image \n",
"* Pass raw images and text chunks to a multimodal LLM for answer synthesis \n",
"\n",
"This cookbook highlights `Option 3`. \n",
"\n",
"* We will use [Unstructured](https://unstructured.io/) to parse images, text, and tables from documents (PDFs).\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",
"\n",
"A seperate cookbook highlights `Option 1` [here](https://github.com/langchain-ai/langchain/blob/master/cookbook/multi_modal_RAG_chroma.ipynb).\n",
"\n",
"And option `Option 2` is appropriate for cases when a multi-modal LLM cannot be used for answer synthesis (e.g., cost, etc).\n",
"\n",
"\n",
"\n",
"## Packages\n",
"\n",
"In addition to the below pip packages, you will also need `poppler` ([installation instructions](https://pdf2image.readthedocs.io/en/latest/installation.html)) and `tesseract` ([installation instructions](https://tesseract-ocr.github.io/tessdoc/Installation.html)) in your system."

"\"This is a dual-axis line chart that illustrates two different datasets over a 30-year period from 1993 to 2022. On the left vertical axis, we have the number of fires, measured in thousands, which goes from 0 to 120. On the right vertical axis, there's the number of acres burned, measured in millions, which ranges from 0 to 12.\\n\\nThe chart shows two lines: one for the number of fires and one for the acres burned. The line representing fires is a solid red line, and it fluctuates over the years, with some peaks and troughs. It appears to have a slight overall downward trend over the 30-year span. The line for acres burned is represented by a gray area chart with a darker outline, and it also shows variability. Notably, the acres burned appear to have an overall upward trend, with some years having significantly higher values than others.\\n\\nThe data points are marked annually, with each year labeled at the bottom of the chart from 1993 to 2022. The chart seems to indicate that while the number of fires has not consistently increased, the number of acres burned per year has generally been on the rise, suggesting that fires may have become larger or more severe over time.\""

In 1993, the number of fires was around 80,000, and the acres burned were approximately 2 million. By 2022, the number of fires appears to have decreased slightly to just under 80,000, while the acres burned have increased significantly to around 10 million.\\n\\nTherefore, from 1993 to 2022, the change in wildfires shows a slight decrease in the number of fires but a substantial increase in the total acres burned.'"
