I copied/pasted a comment with faulty logic (self-defeating) directly from a HN comment and asked a bunch of models available to me (Gemini and Claude) if it could spot the issue. I figured it would be a nice test of reasoning since an actual human missed it. The only one that found the logic error without help was Claude 4.6 Opus Extending Thinking. The others at best raised relevant counterpoints in the supporting argument but couldn't identify the central issue. Claude's answer seemed miles ahead. I wonder if SotA advancements will continue to distinguish themselves.
