# EVAL

> **EVAL(Elastic Versatile Agent with Langchain) will execute all your requests. Like the eval method!**

You don't have to think about how. If you tell them the results you want, they'll search, code, run, and test the Internet themselves, and they'll return the final results.

### EVAL's FEATURE

1. It can **understand** and **generate** data formats for text, image, dataframe, audio (TODO), video (TODO).
2. It can **create tools** that it can use by writing and modifying code.
3. It can **evolve** itself by executing and testing its code.

### BUILT-IN TOOLS

1. Search
   - Google, Bing, Wikipedia
   - Custom DB Search (Currently using Corca's Wine Data in https://www.workershop.kr/en)
     - Use GPT index to quickly find the information you need in a document and use that information to answer
   - Requests.get (Get information from anywhere you want)
2. Terminal
3. Python REPL
4. Image Understanding, Generation, Editing
   - Image Understanding
     - Image Understanding: blip-image-captioning
     - Visual Question&Answering: blip-vqa
   - Image Generation: Stable Diffusion 1.5
