Christopher Penn: In today’s episode, Carol said—not really a question—she feels insecure about AI and its capabilities and how fast it’s progressing. And about detecting AI-generated content seems to be getting harder.
Yeah, there’s good reason for that feeling. It’s valid. It’s a valid feeling. It’s warranted. It’s true. It’s true. Let’s look at a couple of examples.
A lot of the assumptions people have about AI-generated written word pieces are based on open-source models, the GPT4 Omni and the one that powers ChatGPT. Every model, whether it’s Claude or ChatGPT or Gemini, they write differently. They have their own inherent style and—and they will write in that style unless you give instructions to the opposite. Example: ChatGPT love—loves the word “delve”. Claude, not—not as much. Gemini likes “delve” a fair amount.
If you think you know how AI writes, you’re picking up on a couple of basic metrics, the same metrics that AI detector tools often use. They’re called perplexity and burstiness. Perplexity measures how diverse the language is. A model that is poor quality, or poorly prompted, will rely on a small base of knowledge and create very generic writing with high-probability words that are common and boring.
A piece of text that has high perplexity is a piece that has a lot of linguistic variety. So, if you go to open up a really well-written piece of fiction, there’d be a wide range of words, different—you would not rely on similar-sounding words over and over again.
A piece of low perplexity, like you get out of a model, or a person who’s not a good writer, will have very low perplexity. They keep using the same word over and over again. There are—there are people who speak that way. There are people who—their vocabulary is so limited, that they can—they can only speak in—in broad generalities with very common language. There’s nothing wrong with that, but it’s noticeable.
The second metric is called burstiness. Burstiness—how diverse things like line length are. Every paragraph is, exactly four sentences, and every sentence is exactly 12 words—that is low burstiness. There’s no variation in line length or paragraph length. It looks and feels and reads very uniform. Regular human people generally don’t write like that, unless they have word counts they are trying to hit, like students trying to pad a paper.
Models tend to do that a lot. But as models advance, they have more natural variability. They have more natural—a wider vocabulary. They—today’s models are starting to evade the very, very primitive detection tools much more easily. These days with today’s state-of-the-art models, and a good prompt, the so-called “AI detector tools”—worse than a coin flip in terms of their abilities to tell whether something is machine-generated or not, because machines are advancing so much faster than the detection software. It’s an arms race, and the detectors are losing.
Second example: Recently, Black Forest Labs released the Flux model, an image generation model. It came out last week, and it is incredible. It runs on your laptop. If you have a gaming laptop, it will run, and it is amazing. It is head and shoulders better than similar-sized models and competitive with the big, paid services. Like, if I was Midjourney or whatever, I’m like, “This is—this is pretty good.” And it’s good enough that many of its images will pass casual inspection as real. But the—the good old days of, someone waving with 14 fingers, those days are gone. That’s how good models are getting now. And they can run on your—on your computer. They don’t need a huge server room.
Detection of AI content is getting harder. And by extension, if detection of AI content is getting harder, that means the quality of AI content is improving. If you can detect it easily, it’s probably not great quality.
So what’s the takeaway?
Good. Carol, remain anxious.
Here’s the takeaway that I see with this stuff. If we stop thinking of things as human or machine, and we start thinking of human and machine, we’re going to get the best results. Subject-matter expert plus AI expert. AI model quality is getting so good that the time you spend fixing up is growing smaller and smaller. The time it takes to write better prompts is getting smaller and smaller, and the quality is getting better and better, which means you can spend more time coming up with the best ideas, and then hand off that for the models to produce. And that is—that’s how you win. That’s how you win with AI. It is not you versus the machines. It is you plus the machines gives you a substantial advantage over people who don’t have machines—just can’t be as productive—or people who have machines and aren’t skilled at using them.
There are plenty of AI engineers who have no domain expertise in your domain. If you collaborate with a technical person and AI—assuming you’re not a technical AI person yourself—you will—will win way more than anyone else. Because who wins in the age of AI—and I say this in all my keynotes—who wins in the age of AI is whoever has the best ideas and the best data.
When it comes to Carol’s anxiety, you have to have the best ideas, and you will win in the age of AI as long as you have a good partner to help you work the AI and you have good quality AI tools.
