Whisper

I want to install and try Whisper on my own computer.

Official repository: https://github.com/openai/whisper

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.

This runs an AI model on my own hardware. Check my graphics card and memory first, and tell me which version or size of the model will realistically fit. Download model files only from the official page named in the README, tell me how big they are before you download, and run one small example to check it works.

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: Accuracy varies with accent, noise and language. Larger models are slower and need a decent GPU. It gives raw text, not a finished transcript product.
