Studies on political bias in models consistently show that LLMs lean politically left. The only outlier is grok which leans right but by a smaller factor, according to this study for instance: https://arxiv.org/abs/2603.23841
Claiming reality has a left wing bias is certainly an opinion you're welcome to have to explain this, but the reality of the bias in models is well evidenced. It seems that practically Grok's right wing tweaks mostly just combat the already pre baked bias existing models have (generally).
Edit: adding some other studies that are easily retrievable with a quick search for those unsatisfied with the first one - https://arxiv.org/abs/2606.12922 https://arxiv.org/abs/2412.16746
