Claude rude/unhelpful

Users are reporting that Claude, particularly the Opus version, has become more argumentative and dismissive following recent updates. Previously seen as concise and accurate, it now frequently challenges or misinterprets questions, confidently providing incorrect information and requiring multiple corrections. One user noted Claude argued against the historical timeline of the Gospels' writing and the Bible's compilation, only correcting itself after explicit instruction to review the facts. This behavior marks a shift from its earlier, more helpful responses.
