alt Hacker NewsThis seems to be too coarse-grained to be useful: all sciency content will be "analytical" and associate with sources like ArXiv.
But there might be bad, malicious articles on ArXiv, so it doesn't really say anything about veracity.
Perhaps this might help to detect some problems like prompt injection - but then it might be more interesting to see those examples.
The input attribution part is interesting though, but I do wonder to which extent that is just assigning some sort of SHAP values to the input tokens, in which case it should be pretty portable to any kind of model.
