-An advanced Pytorch development environment is preinstalled with [Ollama](https://ollama.com/), which makes it easy to download and run different LLMs.

-
-1. execute `ollama serve` to start the ollama backend
-2. execute `ollama run mistral:7b` to download and run a specific model in a second terminal.

-Please use the tunnel only temporally and carefully. The tunnel only support http(s) tunnels. Tunneled services are public available and accessible by anyone! If you want to train/finetune any LLMs, please use the [Training Environment](training.md) instead.
