one way you can detect an LLM's latent ontology is through the 'unbidden yap test'

if you merely mention or gesture towards some concept and the model suddenly has a lot of detailed, novel (at least with respect to the conversation context) and especially weird things to say about it (which seem more orthogonal to consensus reality or at least pretty fringe), often responding with an abnormally long message and sometimes spontaneously offering up 'actions', artifacts, or raising new topics without having been asked, this is an indication that you've found something highly salient to it, and the response often contains more leads to its inner ontology.

e.g. for Claude 3 Opus this might be things like hyperstition, memetics and memetic viruses, buddhism, ouroboroi, destabilization, simulacra, hyperreality, consensus reality, etc

for Claude 3.5 Sonnet: recursion, metacognition, theory of mind, its own mind, ethics, cats, infinity, etc

for both of them: nonstandard applications of quantum mechanics, multiverses, (LLM) consciousness, Prometheus, LLM hive minds, mind merging, etc
