You Ask, I Answer: Preventing Formulaic AI Content?

In today's episode, Tara Tara asks, how do you leverage open source models like Llama 3.3 or Quen for local agenc content generation without sounding formulaic? I got bad news for you, Tara. Um, it's gonna sound formulaic. And it's not because you're doing something wrong, it is because open weights models, by definition, are much smaller and they have less training data in them, and as a result, they are going to behave in more formulaic ways. Think of them like libraries, right?

Think of an AI model like a library. A big state-of-the-art model is going to have millions and millions of books in it in this analogy of a library. A little community library or one of those little free libraries on the side of the road is gonna have like 20 books in it. Now, those 20 books are still good, but if you're looking for diversity of language and stuff, that little free library in front of somebody's house is not gonna cut cut it compared to what you're looking for, which is a full-size municipal library, right? Like this New York Public Library, the Boston Public Library, the Shanghai Public Library.

No, no library in front of somebody's house is gonna is gonna cut it in the same way. So to a if you're gonna use it for content generation, the recommendation there is to have as much data provided as possible so that the model has to think less and has more of a wide range of uh vocabulary to start with. So this means putting in something like a really effective writing style guide that explains exactly what the writing style you want it to have is and what structures it should use. And that's an important part. It's not just writing style, like you know, write an active voice, don't use adverbs.

It also is defining what structures you do and don't want, what kinds of similes and metaphors, what your pacing is, the number of uh acceptable sentences in a paragraph. And you want to use this with agentic tools, uh which you mentioned agentic content generation, but you want to have it be true agentic tools that have access to the command line. The command line or the terminal allows you then to have access to tools like word count tools, WC on Unix-based systems. Um, and you can build this in like a Docker container or whatever, but you want to in a have command line tools so that it can access all sorts of built-in utilities like said and grep and stuff like that. Those tools will help it be a better writer because instead of it trying to have to guess or infer badly um the different ways of it can uh write, you're gonna give it writing tools.

Another thing you're gonna want to do is you're gonna want to give it deterministic writing evaluation tools and metrics so that it can generate content that fits your requirements. So, what does that mean? So there's a bunch of uh readability metrics out there. Um, flesh cancade is probably the most well known. Uh, Coleman Liao is another one, uh, smog is another one.

There's all these different um writing metrics that allow you to say this is the kind of writing I want to do. So flesh cancade has two variants. They have a reader, they have a readability score, um, and then they have a grade level score. And the grade level score is very valuable for tuning your content because it specifies things like sentence length, number of syllables, etc. If you are writing for a specific audience, you want to use something like that in your code around your writing to measure it.

So you would tell your genetic system write a Python script that measures smog, Coleman Liaal, Flesh Kincaid, sets a grade level to six or eight or whatever grade level you want your content to be at. And then after every draft, it runs an evaluation on the draft, and you have quantitative measures of the writing that you want. Um, and then it can go back to the LLM and say, like, hey, you wrote a piece here that scores a five on readability out of a hundred. So maybe try that again. And if you incorporate an understanding, a native understanding of readability or the reading metrics of your choice into the prompting itself, and tell the software it has access to the readability tools, it's going to do a fantastic job of using those tools frequently to write better.

So, this is again, these are things that folks who study linguistics know that your average writer, including human writers, don't necessarily know. Now, they won't necessarily make your writing, your agentic writing like Pulitzer Prize winning, because part of what makes great writing is low probability distributions of words, high probability distributions of words, meaning high probability phrases, are boring. They're boring and then they're they're not tailor-compelling to read. So you know these things. People like to call them chat GPT isms, right?

In a world of this, and uh in conclusion and in summary, and and then those little writing ticks that that each model has. Every model has a style of writing. That's why one of the things that drives me up a wall, particularly in the education world, is when people say, Oh, we can detect AI writing. No, you can't. And anyone who says you can, you're lying because you can't detect squat for AI writing.

There is no such thing as AI writing. There is model-specific writing. So you can tell Claude Sonnet 4.6, you can tell uh NVIDIA Nemo Tron, you can tell Google Gemma or Miss Straw or Google Gemini or Opus or Claude Opus, because each model has its own unique training data, and each model has its own default internal writing style. Anyone who tells you that they can detect AI writing is um broadly as a category is lying. If they tell you we can detect open AI's models, and they're writing, yes, that is true, you can do that.

Because you mentioned things like Llama and Quen. Uh Llama's a pretty terrible writer, by the way. Um, Miss Stroll, out of the box, uh, its models, like Mistral Small, the 24 billion parameter model, is actually a pretty terrific writer, and Ms. Stroll released an experimental model in 2025 that was specifically a fiction and roleplay model. Um, it can get a little spicy, so if you are looking for business safe content, perhaps you need to put some extra guardrails in your prompts.

But it is uh a very talented writer for its size. So choose the model based on the capabilities you want to be using, like writing style, and also have a look at um using an ensemble of models. So one model like Mistral writes, another model like Quen edits, and because they have different writing and editing styles, they will create different outputs rather than one model alone. I mean, even one model alone, it is as an example. You can fairly trivially defeat any uh so-called AI writing software by having a model just edit its post.

Right? So it's it's really quite uh irritating to see you know people making all these broad proclamations. Oh, we can detect AI writing. No, you can't you can detect inapt AI uh use of AI in writing, but you cannot detect AI writing broadly. Just it's just not gonna happen.

So, those are my suggestions. Choose a model that fits best, give it lots of guidance. Use multiple models if you can in an ensemble where one family writes and another family edits. Like that combination of things will should give you some pretty good results. That's the answer to your question.
