    I’m just saying, but captcha had a purpose. It still kind of does. Whether solved by a person or by an AI.

    I’m pretty sure that for a good while there it was using captcha to help its text recognition more accurately determine what words were from scans of books that were imported en masse to Google books as images of pages. We’re talking about books published before computers were used to write them. The text recognition algorithm had an idea of what the letters should be, but didn’t have a high enough confidence in the result, so it was sent through captcha to get a consensus from humans.

    The humans answering the captcha would just verify whether it was one of a small list of possible matches, and in doing so, train the machine vision algorithm to better detect the letter in the future.

    That’s what I heard at least. IDK. I just live here (on the internet).

    Some disabled people have trouble with captchas, so these days you can download an extension where a robot solves the captcha for you.

    Yeah captchas are done. Soon they will be easier to figure out for AI than for humans.

    This is why Sam Altman is doing his worldcoin thingy with the iris scanners. His idea: One iris (well, two…) is one real human. I’m sure this will be abused though and I absolutely vehemently don’t trust him with my biometrics so no way I will join that.

    I think what we should do is just get used to the fact that the internet now consists of humans and AIs. Learn to take things with a grain of salt.

    There’s a lot of misunderstanding in this thread about how captchas work.

    What modern captchas examine isn’t actually your ability to solve the puzzle… It’s how you solve it. Things like mouse movements and how you type are big factors. So a bot would process for a moment, and then basically copy and paste in the answer, whereas as a human is going to type at a normal pace, often with pauses as they double check the details. Same goes for the click the tiles challenges. A bot will work through systematically, a human will bounce around, and their timings will be very different.

      Captchas have largely been solvable by machines at a rate higher than humans for a long, long time.

      It is very easy to train a model to behave like humans do by simply having a sample of human inputs.

      Here is an article from august 2023 covering how much better machines are than humans at accomplishing captchas of many flavors. Sauce

    I wonder how that works on a Japanese captcha. I know people have had issues shortly after moving but not knowing the language at all yet trying to set some things up.

    The “puzzle” isn’t the test, the test uses your browser history, mouse activity, etc to identify you as human (or not). The puzzle is used to generate training data for ML models.

      it’s the recaptchas that they should have trouble with. since it’s not just about finding the right picture, it’s also about the time between clicks, the way the mouse moves, etc.

          but us humans aren’t truly random, we probably behave in similar ways to each other, but also have individual ‘fingerprints’. like the time it takes between keystrokes, or the length of time we spend holding the button on the mouse down while clicking. we could probably come up with a way of identifying someone based only on that kind of data. what was i talking about?

            Not without enough context to know what time of day, if the person is ill, or a ton of other things that would make someone respond differently at different points in time.

            The anti bot stuff is going to be looking for too much consistency, which is hard look for on its own before trying to look for some kind of ‘fingerprint’

        Yeah, and a couple of people I know who were consistently reported to be robots because they’ve been shown captcha too much and as a result solved it too well. Which in turn led to more captcha and improved solving speed. Well, you see the problem, I guess

                  Man the models can’t store verbatim its training data, the amount of data is turned into a model that is hundreds or thousands of times smaller than the original source data. If it was capable of simply recovering everything that it was trained on this would be some magical compression algorithm and that by itself would be extremely impressive.

                  They do not store anything verbatim; They instead store the directions in which various words and related concepts relate to one another in some gigantic multidimensional space.

                  I highly suggest you go learn what they actually do before you continue talking out of your ass about them

        The majority of people right now are fairly out of touch with the actual capabilities of modern models.

        There’s a combination of the tech learning curve on the human side as well as an amplification of stories about the 0.5% most extreme failure conditions by a press core desperate to feature how shitty the technology they are terrified of taking their jobs is.

        There’s some wild stuff most people just haven’t seen.

          At the risk of sounding like a tech bro who’s desperately trying to secure funding: this truly does feel like a major leap in technology that is going to change the world.

          Anytime I hear it dismissed as “basically auto-complete”, I feel like it’s being underestimated.

            It’s not just underestimation, it’s outright misinformation.

            There’s so much research by this point over the past 18 months that there’s an incredible amount going on beyond “it’s just a Markov chain, bro.”

            It was never a Markov chain as that ignored the self-attention mechanism which violated the Markov property. It was just some people trying to explain it used a simplified description which went viral.

            Sometimes talking to people who think it’s crap feels like talking to antivaxxers. The feelings matter more than the research and evidence.

            Its kind of funny because autocomplete on phones is definitely moving in the direction of using LLMs. Its like it wasn’t true when people started saying it, but it will be literally true in a couple of years at most.

          I can just as well say that the screenshot above is the top 0.5% pushed by people trying to sell the tech. I don’t really have an opinion either way tbh, I’m just being cynical. But my own experience with those tools hasn’t been impressive.

            At a pretrained layer, the model is literally a combination of a normal distribution curve of capabilities.

            It can autocomplete a flat earther as much as a Nobel physicist given sufficient context.

            So it makes sense that even after the fine tuning efforts there’d be a distribution in people’s experiences with the tools.

            But just as the average person’s output from Photoshop isn’t going to be very impressive, if all you ever really see is bad Photoshops and average use, you might think it’s a crappy tool.

            There’s a learning curve to the model usage, and even in just a year of research the difference between capabilities of the exact same model from then to now is drastically different, based only on learnings around better usage.

            The problem is the base models are improving so quickly the best practices for the old generation of models goes out the window with the new. So even if there were classes available I wouldn’t bother pointing you to them as you’d just be picking up info obsolete by the time the classes finished or shortly thereafter.

            I’d just strongly caution against betting against the tech’s continued capabilities and improvements if you don’t want to be surprised and haven’t taken the time to look into them operating at their best.

            The OP post is pretty crap compared to the top 0.5% usage.

        I don’t remember actually but I checked the file metadata and I have the template in my downloads folder next to this which has an exif tag of 2 minutes later with gimp metadata so I’m pretty sure I must have made it, which makes it a bit more impressive since I probably just sent it to friends privately and didn’t post it anywhere it could have been scraped for training.

      Yes it probably can… CAPTCHAs don’t work based on your answers (many types you can answer wrong and still sometimes pass) - they work by tracking your mouses movements and timing and deciding whether they human-like.

            I’m stubborn. I refuse to give the machine the answer I know it wants. And no, that overpass is not a bridge. Usually there is an option to skip or verify another way, This is when the captcha drops the ruse and it’s clear that the machine was just analyzing my mouse movements and response timings anyway to verify that I was behaving randomly in a human way. Still a better game than any of those in YouTube ads.
