    There was this post a few days ago <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=49797323">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=49797323

    It had this to say in the linked post:

      This led to the natural question: can gzip do language modeling? (...). Here’s some real, unedited output after priming it on tiny Shakespeare:
    
      gzipt --corpus data&#x2F;tinyshakespeare.txt --prompt $&#x27;MENENIUS:\n&#x27; --length 200
    
      MENENIUS:
      &#x27;Though all at once canq
    
      MARCIUS:
      Pray now, nocamest thou to a morsel.
    
      LARTIUS:
      Hence, and
      I&#x27; the end admire, where G
      again; and after it ag .
    
    Now thinking back, what&#x27;s missing so that gzip could unwind the correct body of work from Shakespeare is just a correct sequence of bytes. One way to arrive at this is by just getting the body of work and doing the inverse, compressing it to get that golden sequence of bytes.

    The other is what thinking does, it tries to predict the missing sequence of tokens from a high entropy source, the prompt, in order to increase the likelihood of correctly decompressing the desired results from its weights.

      I don&#x27;t know how this is related, but it reminds me of how I have always believed compression to be the ultimate sign of intelligence. If you can reduce something while keeping comprehension, you are finding more abstract symbols to represent the information of the original source.
