Sorry, I don't understand what you mean. Unfortunately it's not easy to try the current version of Cyc and there's not a lot of information about it easily accessible either.

You can also consider Watson, different to Cyc in that its knowledge base was built with a lot of machine learning, including some neural nets. It wasn't an LLM but the original version (before corporate went at it and destroyed it) was perfectly capable of interacting in an open-ended manner, notably winning at Jeopardy years before BERT was a glimmer in Jacob Devlin's eye.

I note again that you were the one who brought common sense reasoning in the conversation but there's a large literature on rule-based systems that do that based e.g. on non-monotonic logics. You should familiarise yourself with that literature before engaging in dares with strangers on the internets.
