llama.cpp

I want to install and try llama.cpp on my own computer.

Official repository: https://github.com/ggml-org/llama.cpp

Before you do anything:
1. Read the README and install notes in the official repository above, and nothing else. Do not follow third-party tutorials or mirrors.
2. Tell me in plain words what will be installed, what it needs (operating system, memory, graphics card, disk space, accounts) and what it will cost me, if anything.
3. Check my computer against those needs and tell me honestly if it will not work well.

Install it in an isolated environment so it does not touch the rest of my system (a virtual environment, pipx, or the official install script after I have seen what it does). Use the official install command from the README.

Rules:
- Show me each command before you run it, and say what it does.
- Ask before anything that deletes files, changes system settings, opens a network port or needs an administrator password.
- Never put my passwords or keys on a command line, or in a file I did not choose.
- When it is installed, help me check it with one small test, and tell me how to start and stop it.
- If something goes wrong, explain it in plain words and do not guess your way around it.

Good to know before you start: It is a developer tool, not a friendly app. Most people are better served by a front end such as Ollama or Jan.
