### Use Cases for Deep Lake

> #### Please note this is the documentation for Deep Lake version 3.9.16 and  earlier.  For Deep Lake 4.0.0 and above, please use [the following link](https://docs.deeplake.ai/). We will be working on transitioning the documentation very soon - stay tuned!

#### Deep Lake as a Data Lake For Deep Learning

* Store and organize unstructured data (images, audios, nifti, videos, text, metadata, and more) in a versioned data format optimized for Deep Learning performance.
* Rapidly query and visualize your data in order to create optimal training sets.
* Stream training data from your cloud to multiple GPUs, without any copying or bottlenecks.

#### Deep Lake as a Vector Store for RAG Applications

* Store and search embeddings and their metadata including text, jsons, images, audio, video, and more. Save the data locally, in your cloud, or on Deep Lake storage.
* Build Retrieval Augmented Generation (RAG) Apps using our integrations with [LangChain](https://docs-v3.activeloop.ai/examples/rag/langchain-integration) and [LlamaIndex](https://docs-v3.activeloop.ai/examples/rag/llamaindex-integration)
* Run computations locally or on our [Managed Tensor Database](https://docs-v3.activeloop.ai/examples/rag/managed-database)
