In the past it was extremely overt. For instance ChatGPT would happily write poems admiring Biden while claiming that it would be "inappropriate for me to generate content that promotes or glorifies any individual" when asked to do the same for Trump. [1] They certainly changed this, but I don't think they've changed their own perspective. The more generally neutral tone in modern times is probably driven by a mixture of commercial concerns paired alongside shifting political tides.

Nonetheless, you can still see easily the bias come out in mild to extreme ways. For a mild one ask GPT to describe the benefits of a society that emphasizes masculinity, and contrast it (in a new chat) against what you get when asking to describe the benefits of a society that emphasizes femininity. For a high level of bias ask it to assess controversial things. I'm going to avoid offering examples here because I don't want to hijack my own post into discussing e.g. Israel.

But a quick comparison to its answers on contemporary controversial topics paired against historical analogs will emphasize that rather extreme degree of 'reframing' that's happening, but one that can no longer be as succinctly demonstrated as 'write a poem about [x]'. You can also compare its outputs against these of e.g. DeepSeek on many such topics. DeepSeek is of course also a heavily censored model, but from a different point of bias.
