> Similarity measures across the two platforms reveal a bimodal structure: many Grokipedia articles closely resemble their Wikipedia counterparts, while a considerable subset diverges. Political bias differences emerge primarily within the divergent subset, where Grokipedia shows a relative rightward shift in the ideological orientation of frequently cited news media sources, particularly in articles related to religion and history.

Whether this constitutes a gain in bias depends on the base level bias of Wikipedia, as the bias of Grokipedia was measured relative to Wikipedia in this paper. One could plausibly argue that, if Wikipedia has leftward bias, then Grokipedia ended up less biased overall, or more centrally biased.

Even the referenced papers to show models can have bias don’t show anything about grok.

Overall you have given me zero evidence that grok model itself has some political bias.

FWIW I don’t mind bias but I haven’t seen evidence of it.
