I was a bit skeptical, so I asked the model through the claude.ai interface "who is the president of the United States" and its answer style is almost identical to the prompt linked
Meanwhile, I also asked the same to sonnet 3.7 through an API-based interface 5 times, and every time it hallucinated that Kamala Harris is the president (as it should not "know" the answer to this).
It is a bit weird because this is very different and larger prompt that the ones they provide [0], though they do say that the prompts are getting updated. In any case, this has nothing to do with the API that I assume many people here use.
