You can take the open source models and fine tune them to take on any persona you want. A lot like what the Flux community doing with the Boring Reality fine tune.
We are all enjoying/noticing some repeatable wack behavior of LLMs, but we are seeing the dual wack of humans revealed too.
Massive gains in neural type models and abilities A, B, C, ..., I, J, K, in very little time.
Lots of humans: It's not impressive because can't L, M, yet.
They say people model change as linear, even when it is exponential. But I think a lot of people judge the latest thing as if it somehow became a constant. As if there hasn't been a succession of big leaps, and that they don't strongly imply that more leaps will follow quickly.
Also, when you know before listening that a new artifact was created by a machine, it is easy to identify faults and "conclude" the machine's output was clearly identifiable. But that's pre-informed hindsight. If anyone heard this podcast in the context of The Onion, it would sound perfectly human. Intentionally hilarious, corny, etc. But it wouldn't give itself away as generated.
OpenAI considers this phenomenon a software bug
I think that's what makes notebookllm so realistic. To me this is my perception of all podcasts
