Hello, world!

This is showcase how to make own server with Llama2 model.
I'm using here 7b model just for example. Also here's only CPU power.
But you can use GPU power as well!

How to GPU?

Change `CMAKE_ARGS="-DLLAMA_BLAS=ON -DLLAMA_BLAS_VENDOR=OpenBLAS` in Dockerfile on `CMAKE_ARGS="-DLLAMA_CUBLAS=on"`. Also you can try `DLLAMA_CLBLAST` or `DLLAMA_METAL`.

How to test it on own machine?

You can install Docker, build image and run it. I made `run-docker.sh` for ya. To stop container run `docker ps`, find name of container and run `docker stop _dockerContainerName_`
Or you can once follow steps in Dockerfile and try it on your machine, not in Docker.
