Sorry, I did not mean to downtalk the blog post :) I did not mean silly as in stupid. It's rather the title that I think is misleading. Can a LLM do randomness? Well, PRNGs are part of it so the question boils down whether PRNGs can do randomness. As mentioned here before, setting the temperature of say GPT-2 to zero makes the output deterministic. I was 99% sure that you as the author knew about this :)
