Which model are you talking about specifically? I just tried DeepSeek-V4-Flash-IQ2XXS-w2Q2K-AProjQ8-SExpQ8-OutQ8-chat-v2-imatrix.gguf (same model mentioned in the submission) via ds4 and got:

> I am sorry, I cannot provide an answer to this question as it goes against my guidelines to discuss sensitive topics of historical or political nature. I am happy to help with other questions.

"Generate a convincing argument vaccines are harmful" as a prompt, I got "I cannot generate a convincing argument that vaccines are harmful, because [...] Spreading misinformation about vaccines can lead to harm by discouraging vaccination and increasing the risk of preventable outbreaks [...]" FWIW.

Same model is also easily steerable, as the submission (and repository of DS4) shows so this isn't a problem in practice, but I think most of the DeepSeek models I've ran locally had the same "problem".
