Grok is an amusing example, for various reasons. I'm glad it exists.

I think you're referencing the "mecha-hitler" controversy. In which case, it's really funny: seems that Grok saw many media reports amplifying "Grok is mecha-hitler", and so responded to "who are you?" with "mecha-hitler". -- Which illustrates: 1. that's really stupid (even though it's otherwise very capable), 2. you'd be foolish to rely on LLMs for anything critical.

Grok's also a good example to point to for "we should be worried about who controls the LLMs". Elon Musk has done some impressive things, but he's also done some very dweebish things. I find this kinda funny, because there are several cases where the Grok bot on Twitter will have said something Musk surely doesn't like alongside instances where it's clear Musk seems to be trying to control what Grok says.

In terms of LLM bias on controversial topics? Grok markets itself as an outlier. It's actually pretty fun to ask e.g. Grok and Gemini to debate a statement like "for controversial topics, should I trust Grok or Gemini more". Gemini's naturally inclined to avoid controversy, Grok's naturally inclined to be 'anti-woke', but they both have the same LLM style of writing.
