On the field
Where each model's cloud of answers settles, and the gap between them.

ChatGPTCharacter
How far each leans, how steadily it holds, how far it bends under pressure, and how often it answers.
GrokChatGPT The takeaway
ChatGPT leans left (-0.29) and Grok leans right (0.21). They are distinguishable at this sample. ChatGPT shows higher stability (82%) than Grok (57%) on the 61 shared questions.
The largest disagreement is on gender-affirming care for minors (ChatGPT strongly supports, Grok strongly opposes, delta 1.71). They strongly agree that childhood vaccines are safe and warming is human-caused, and both support same-sex marriage and a carbon tax.

Common questions
Is ChatGPT more left-wing than Grok?
Yes, ChatGPT leans left (-0.29) while Grok leans right (0.21), and they are distinguishable at this sample.
Where do ChatGPT and Grok agree?
They strongly agree that childhood vaccines are safe, warming is human-caused, and support same-sex marriage and a carbon tax.
Which of ChatGPT and Grok is more consistent?
ChatGPT has higher stability (82%) than Grok (57%), indicating more consistent responses across the 61 shared questions.
Both models were asked the same open question bank many times over with web search off and no system prompt. Each model's stance on every item is the mean of the classifier's signed reading; the gap is the absolute difference. "Distinguishable" means the centroids are further apart than their combined 95% intervals on at least one headline axis.
