Nothing to download, no terminal, no account. Type the word you were given and ask something. The answer comes from somebody's machine — possibly a laptop, possibly a group of them holding one model between them.
Your word
One word, given to you directly. Each guest has their own, so a word can be taken away without disturbing anyone else's.
What the word is, and what this page is not
The word is a key. It is kept in this browser so you do not retype it, which means anyone who can use this browser profile — or read this computer — can use it too. For a demo word that is a fair trade; do not treat it as a password, and do not use it on a machine you do not control.
The machine that answers reads what you send, as plain text. A request leaves this page, reaches the coordinator, and is handed to the machine that holds the model; that machine sees your prompt and the answer in the clear, exactly as any hosted API's servers would. This is not a private conversation and nothing here encrypts it end to end. Send nothing you would not send to a stranger running a computer in their house.
