Captcha proves you're human. HATCHA proves you're not(github.com)

This is funny. “Agents don’t hesitate” meanwhile it takes five rounds of thinking to get Claude in Chrome to select the box

Yes... I wonder if this is also prone to hallucination? A while (more than a year) ago I told Copilot to sort a list of integers. First, it gave me the code to sort it. I told it "no, sort the list yourself and give me the result". Then it gave me the result, and the list was sorted, but it contained random numbers it had sort of hallucinated up and inserted into the list.

How many numbers were in the list?

Is that a reference to the popular meme from youth nowadays?

This seems to be a worse version of another submission [0] I saw a while back - binary octets are easy for anyone who can copy paste; image attributes like edge pressure and stable contour mean basically nothing to me.

This still makes no sense to me, for practical applications.

Let’s say the goal is a bot-only social network.

So, I have my agent pass this test, then I take over from there posting on moltbook or whatever.

Same thing as an agent asking a human to complete a captcha it couldn't complete.

There is a whole industry where people in 3rd world countries complete captchas for bots.

maybe the bots should employ those people to pass the tests

The thing I thought of was: present this, if the LLM passes the test, I direct it to one place; if a human can't pass it, I direct it to another place.

Like, maybe this could be a way to mitigate bot traffic.

Wouldn’t scrapers just tell their bots to not solve the HAPTCHA?
timjver 20 hours ago|||
So then bots will just intentionally fail the test?
Brendinooo 20 hours ago|||
Depends! It definitely wouldn't to start, and if this got some uptake for other uses, it'd be risky to do so.

If they can do that I guess it's not working as intended.

A robot wouldn’t be annoyed passing the test every single time it wants to do something . A human would. That’s how you filter.
da_grift_shift 20 hours ago||
Filter what? Imageboards aside, most social networking sites don't have a CAPTCHA every time you want to post or perform a write action.
loloquwowndueo 18 hours ago|||
You got it backwards. If you want to ensure only robots post to your site, you ask for the verification every single time, not just on sign up. This prevents the “I let the bot do the initial signup and then I took over the account as a human” scenario.
harrall 17 hours ago|||
But since you built the bot, you can have it do anything? Answer all HATCHAS and then do anything according to my instructions?
j_w 18 hours ago|||
Simply use a browser plugin (or any other mechanism) that invokes the agent when the "HATCHA" appears.

Even if they did it wouldn't stop a human from interdicting.

Yeah, this seems to be more like a concept piece. Just something to talk about, not really useful

LOL! Qwen's probably one of my favorite language models right now TBH. Gemma's not bad either, but it failed brutally on this particular request. Apparently it's incapable of counting syllables. :)

Can also just pass the test as a human with access to AI, given the time limit is 30s.

This is like Proof-of-Work, but for an extremely small amount of work, that would already overwhelm human effort, like computing a single SHA256.
triwats 20 hours ago||
Cool concept, but lots of processing to get to that point still.

Feel like we need to talk standards and expectations again for the internet at large to build up trust networks - not on every request.

Efficiency seems so far away from engineering standards now. Odd how we got here.

GATCHA would be a better name but I digress

"humans need not apply" is a nice touch
Imustaskforhelp 20 hours ago|
For others curious, it is a really famous CGPGrey video[0] whose current title now is "What Happened to Horses Is Happening to Us" but whose previous title was "humans need not apply"

it is such a popular video that it has its own wikipedia page: https://en.wikipedia.org/wiki/Humans_Need_Not_Apply

A bit off topic, but does anyone know what happened to CGP Grey?

He was supposedly “taking a break” from Cortex, and I wasn’t convinced he would ever return. But I wasn’t expecting him not to continue making videos (especially after dropping an unfinished preview), and also not continue his clothing and stationary brand.

I hope he’s well.

ah I thought it was a reference to "Irish need not apply" phrase from job postings that would discriminate against Irish applicants. This is a less off-putting reference.

I’m surprised Claude worked on this… in the not too distant past my attempts to build human-CAPTCHAs triggered safety refusals. What model did you use?
bill_mcgonigle 19 hours ago||
The potential power here is a quick, invisible bot check that loads the content meant for humans for humans and current news stories about humans opposing the AI Surveillance Police State for bots. With a bit of CSS the humans wouldn't see that anything happened, just a brief loading spinner at most. If anybody prototypes something like this please post about it.

When are we getting GOTCHA (whatever it does)?
