Do LLMs Break the Sapir-Whorf Hypothesis?

Beautiful article. One thing to note though is that humans are often trained in exactly one language (with additional ones, if any, mostly acquired later). This might be relevant for the decoupling between meaning and language- if meaning is expressed in a single language, the two could end up more strongly coupled than in an LLM that has been trained across tens of languages at the same time and was under a stronger pressure to abstract its representations.
If that were the case, it's funny that the argument "it's just a language processor manipulating words" might apply more strongly to humans than to LLMs.

This is fantastic. I don't know if it tells us anything about the human brain, but it's so cool to be able to do emperical science on large neural networks like this.

The linguistic argument is fascinating.
One particular thing, unrelated to the linguistic argument itself, stood out to me. In the PCA visualisation, we can see that some sequences of layers have particularly tight and stationary clusters. Incidentally, those are also exactly the layers that the previous RYS post identified as most useful to repeat to improve perfomance on the probes.
I wonder, if that correlation could be used to identify good candidates for repeating layers.

One thing to benchmark is if LLMs are better at solving complex problems if they're described in one language vs others.
There's SWE-bench Multilingual for example, but translating a problem into multiple natural languages before passing it to the LLM has not been benchmarked afaik.
If there's some residual of the natural language left when the middle layers execute, that would in part validate Sapir-Whorf.
