Author here, was a bit surprised to see this here. I thought there needed to be a good zero-JS LLM site for computer people, and we thought it would be fun to add various other protocols. The short domain hack of "ch.at" was exciting because it felt like the natural domain for such a service.

It has not been expensive to operate so far. If it ever changes we can think about rate limiting it.

We used GPT4o because it seemed like a decent general default model. Considering adding an openrouter interface to a smorgasbord of additional LLMS.

One day, on a plane with WiFi before paying, I noticed that DNS queries were still allowed and thought it would be nice to chat with an LLM over it.

We are not logging anything but OpenAI must be...

Do you mind if I know how much you paid for the domain, brilliant find.

.at is Austria TLD, in case anybody was wondering

There used to be a service where DNS requests to FOO.that-service.org would return the abstract for the Wikipedia article "FOO".

edit: I think it was this one, seems to be defunct now: https://dgl.cx/2008/10/wikipedia-summary-dns

Cool! Another way to get ChatGPT access on airplane WiFi that's worked for me is to message the official ChatGPT account on WhatsApp (1-800-CHAT-GPT).

One interesting thing I forgot to mention: the server streams HTML back to the client and almost all browsers since the beginning will render as it streams.

However, we don't parse markdown on the server and convert to HTML. Rather, we just prompt the model to emit HTML directly.

Considering the target audience it probably doesn’t matter but it sounds like this could lead to pretty heavy prompt injections, user intended or not. Have you considered that and are there any safeguards?

The domain is great by the way. Congrats on getting it!

Random thought popped i my head you could allow for cool setups/prompts as sub domains.

something.ch.at is some web space for somebody else's showcase. (within reason of course)

real cool idea, re: being able to use a LLM over DNS in a plane.

Well, no worries, it's here now!
