Aren't LLMs just super-powerful pattern matchers? And guessing "taps" a pattern recognition task? I am struggling to understand how your experiment relates to intelligence in any way.

Also, commercial LLMs generally have system instructions baked on top of the core models, which intrinsically prompt them to look for purpose even in random user prompts.

I like the high level idea! (how do we test intelligence in a non functional way?)

I'm effect, the different response types are measuring how the models respond to a context-free novel environment. I imagine humans would also respond on a variety of ways to this test, none of which are necessarily incorrect from the perspective of intelligence testing .

Many tests of human behavior (eg, n behavioral economics) create some pretense context to avoid boarding the response that is actually being measured. For example, we may invite a participant to a study of color preference, but actually measure how fast they complete the task when the scientist has/hasn't bathed in a week (or whatever).

Likewise, for llm intelligence testing, you could create pretext tasks and context, and perhaps measure what the model considered along the way, instead of the actual task outcome.

There's definitely more than "just" pattern matching in there - for example, current SOTA models 'plan ahead' to simultaneously process both rough outlines of an answer and specific subject details to then combine internally for the final result (https://www.anthropic.com/research/tracing-thoughts-language...).

On alternative ways to measure LLM intelligence, we had good success with this: https://arxiv.org/abs/2509.23510

In short: start with a dataset of question and answer pairs, where each question has been answered by two different LLMs. Ask the model you want to evaluate to choose the better answer for each pair. Then measure how consistently it selects winners. Does it reliably favor some models over the questions, or does it behave close to randomly? This consistency is a strong proxy for the model’s intelligence.

It is not subject to dataset leaks, lets you measure intelligence in many fields where you might not have golden answers, and converges pretty fast making it really cheap to measure.

Eh that is still encompassed by the term “pattern matching” in this context. Sure it’s complicated, but it’s still just a glorified spell checker.

LLMs are pattern matchers, but every model is given specific instructions and response designs that influence what to do given unclear prompts. This is hugely valuable to understand since you may ask an LLM an invalid question and it is important to know if it is likely to guess at your intent, reject the prompt or respond randomly.

Understanding how LLMs fail differently is becoming more valuable than knowing that they all got 100% on some reasoning test with perfect context.
