Definition of what? Do I think that because llms use a kv cache during inference, that proves they can experience things? You're gonna have to explain your thought process. To me, the particular algorithm used is not the philosophical crux of the issue.
There's a separate idea of caching the kv cache between requests
I've never heard of this anyways. The kv cache is specific to a particular input, it can't be reused for a subsequent prompts.
