> I want any LLM I use to choose the very best, most precise words at every single decision point. Then bad news: LLMs already use randomness in a fundamental way. Each time they go to generate a token, they first generate a probability distribution of possible tokens. Then they pick one randomly according to this distribution. The technique described can be thought of as making the random number generator pseudo ran…
I think this is a key reason why humans write better prose than LLMs - we can try to choose the best word every time, and go back and restructure sentences and paragraphs if we want. On the other hand, LLMs are forced into picking some likely-ish word, and then have to build the rest of their response to retcon that choice into making sense. Even good human writers would probably struggle with this constraint. It wou…
They are also usually worse (which is often better!) because they are usually lazy and don’t want to spend effort they do not have too, to accomplish their goals.
Their goals are often complex and nuanced.
None of this is true of LLMs.
