Believable because:

However, the system is highly specialized for scientific journal articles. When presented with real articles from university newspapers, it failed to recognize them as being written by humans.

So outside of its purview? Agree.

Why?

Chatgpt writes them all the same. So its not so much “an AI wrote this” as it is “Bob always writes like this, we know Bob wrote this because _____”

It’s a bad headline, but the article immediately clarified.

All of these were written by chatgpt:

To make toast, start by plugging in your toaster and adjusting the browning setting to your preference. Take a slice or two of bread and place them into the toaster slots. Push down the lever to activate the heating elements. Wait for a few minutes until the toaster automatically pops the toast back up, indicating it’s ready. Carefully remove the toast and spread your desired toppings, such as butter or jam, to taste. Enjoy your warm, crispy toast, a simple and satisfying breakfast or snack.

In the pursuit of achieving the toasted state of bread, one must first interface with an electrical device colloquially known as a toaster. This remarkable appliance harnesses electrical energy to generate heat through resistive elements. Place slices of bread in the designated slots, ensuring that the toaster is appropriately powered, and set the temporal parameter of toasting, often denoted as “browning level,” to the desired degree of crispiness. Activation is achieved by engaging the mechanical lever, prompting the transformational process, during which thermal energy is conveyed into the bread, inducing a Maillard reaction that alters its molecular structure. Upon the cessation of this temporal journey, the toaster signals completion. Carefully extract the now-toasted bread, apply preferred condiments, and savor this culinary endeavor.

Alright, so like, to make some bomb toast, you gotta start by pluggin’ in that toaster thingy and crankin’ up the toastiness level, you know, like, how crispy you want it. Then you grab your slices of bread and just slide ‘em into those slots in the toaster, pop the sucker down, and hit the magic button to fire it up. While you’re waitin’ for the toasting action to go down, you can do a lil’ dance or somethin’, and when it’s done, it’s like, bam, your toast is ready, girl! Grab it, slather on some butter or whatever floats your boat, and get your snack on – it’s, like, totally yum!

Well, back in our day, making toast was a straightforward affair. First, you’d plug in your trusty toaster and set the browning knob to your liking. Then, take a couple of slices of good old-fashioned bread, none of that fancy stuff, and place them gently into the toaster slots. Press down the lever, and as the heating elements did their work, you’d have time to catch up on the morning paper. When the toast popped up, simply retrieve it with a fork or a butter knife, add some butter, and there you had it – a simple, no-fuss breakfast, just the way we liked it. Those were the days, my friend.

Seriously, making toast is, like, the most basic skill ever, and it’s so obvious that anyone who doesn’t get it must be, like, a total amateur. You just plug in that toaster and adjust the settings for your personal taste – it’s not rocket science, people! Then, grab some bread, any kind you want, and drop it into the slots, it’s not that hard. Push the lever down, and boom, the heat does its thing. It’s, like, literally impossible to mess up. But I guess there are still some folks out there who, like, need to argue about every little detail because they just can’t accept that not everyone is a culinary genius. 😒🍞 #ToastGate

No, if chatgpt does not write it all the same.

It’s hilarious watching people act like AI is so good that AI can’t tell an AI wrote something.

To you those might seem completely different, but you’re overestimating AI on one side and underestimating on the other.

It’s a hell of a lot easier for AI to check for similarities than it is to write something without similarities, even if a human can’t see them. Checking is always easier than producing for AI

As I understand it, one of the ways AI models are commonly trained is basically to run them against a detector and train against it until they can reliably defeat it. Even if this was a great detector, all it’ll really serve to do is teach the next model to beat it.

That’s how GANs are trained, and I haven’t seen anything about GPT4 (or DALL-E) being trained this way. It seems like current generative AI research is moving away from GANs.

I know it’s intrinsic to GANs but I think I had read that this was a flaw in the entire “detector” approach to LLMs as well. I can’t remember the source unfortunately.

Also one very important aspect of this is that it must be possible to backpropagate the discriminator. If you just have access to inference on a detector of some kind but not the model weights and architecture itself, you won’t be able to perform backpropagation and therefore can’t generate gradients to update your generator’s weights.

That said, yes, GANs have somewhat fallen out of favor due to their relatively poor sample diversity compared to diffusion models.

No references whatsoever to false positive rates, which I’d assume are quite high. Also, they single out that they built this detector to catch chemistry-related AI-generated articles

If you call heads 100% of the time, you’ll be 100% accurate on predicting heads in a coin toss.

I really really doubt this, openai said recently that ai detectors are pretty much impossible. And in the article they literally use the wrong name to refer to a different AI detector.

Especially when you can change Chatgpt’s style by just asking it to write in a more casual way, “stylometrics” seems to be an improbable method for detecting ai as well.

It’s in openai’s best interests to say they’re impossible. Completely regardless of the truth of if they are, that’s the least trustworthy possible source to take into account when forming your understanding of this.

openai had their own ai detector so I don’t really think it’s in their best interest to say that their product being effective is impossible

Willing to bet it also catches non-AI text and calls it AI-generated constantly

The best part of that if AI does a good job of summarizing, then anyone who is good at summarizing will look like AI. Like if AI news articles look like a human wrote it, then a human written news article will look like AI.

The original paper does have some figures about misclassified paragraphs of human-written text, which would seem to mean false positives. The numbers are higher than for misclassified paragraphs of AI-written text.
