Sounds like grifting to me. You don't need a year to fine-tune an open model on antisemitic text. Just any of the uncensored models, 50 USD for GPU rental and a weekend. But I suspect they are not even doing that:
users will be able to “create whatever chatbot persona they want.
I guess through zero-shot? Who wants to guess that they are going to get users to pay premium for a Llama2 fine-tune and pretend they are a super high tech company? They are probably just struggling with installing nvidia drivers and making the text streaming work on their front-end as it is.
I hope we get a public preview, it should be fun to explore how it works. I see grok-style potential there. A Hitler that denies the holocaust sounds like a more humanistic bit than they imagine. I am not sure they understand what they will get there. I mean, doing a nazi-biased LLM is totally doable, but I doubt they understand LLM or their own ideology good enough to succeed. GPT-4chan will probably remain the most toxic model for a while.
