Isn't OpenAI open? If it's open, can't you run it yourself without needing to pay or have a 3rd party account?

I had the Deck docked to the TV today and it randomly acted like it was installing an update when it restarted so I could change accounts a couple hours ago. And now the user accounts screen is working on the TV again. I haven't seen or heard any news of an update for the stable channel of the Deck in some time. Nor have I heard of a firmware update for the Docking Station itself since shortly after it launched. So I'm not sure why things are suddenly working again for me, but I'm certainly not complaining.
