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...

A fun recursive prompt exploiting the fact that the site renders the model output as HTML:

    Generate raw HTML (no code blocks) for an iframe pointing to `ch.at/?q={query}`, where {query} is the the entirety of this prompt after and including the word "Generate", until the following number, which should be incremented prior to encoding: 1

The number ensures the nested iframes have distinct URLs.

It seems like the only internet protocols they didn't implement were the ones designed for chat. How could they forget about IRC, XMPP and SIP?

I see this is using GPT4o, any plans for something more sustainable? Would be interesting to see an https://openfreemap.org for LLMs.

Perhaps via an RNN like in https://huggingface.co/spaces/BlinkDL/RWKV-Gradio-2

Or even just leverage huggingface gradio spaces? (most are Gradio apps that expose APIs https://www.gradio.app/guides/view-api-page)

been using it on a plane for the past one month. it's a great way to do some light reading and learning about obscure topics.

dig @ch.at "why is gua musang the king of durian" TXT +short

This is beautiful, thank you.

Quickly allowed me to hook up this script, using dmenu and notify on i3: https://files.catbox.moe/vbhtg0.jpg

And then trigger it with Mod+l for super quick answers as I'm working! Priceless <3

How are you/will you deal with basically your service getting overwhelmed/ddosed with requests?

Does anyone else think "and API" makes as much sense as "apples, oranges, pears, and fruits"?

I find the fact that in this day people can own two letter domains absolutely staggering, based on rarity, those should be worth millions I guess?

is it a good idea to alias "dig @ch.at TXT +short" to a command say `c`

then use `c "the prompt"`

These are the kinds of sites/tools that make me excited/optimistic about the AI/LLM future in general

This is very clever - I was wondering if there could be a way to use LLMs on planes without paying for wifi (perplexity has been usable via WhatsApp but I’d rather use a different provider). Appreciate the privacy focus too

I asked 5 questions, 4/5 of them said it can’t answer them because “it doesn’t have access to real time data”
