How to finetune GPT3 to sound like my funny uncle?

This is the million dollar question I have too, but have yet to really sit down and experiment with it.

But to extract a personality, I am thinking of embeddings or fine-tunes.

For fine-tunes, see my babbling rant at Extracting Personalities from past Conversations?

For embeddings, I haven’t posted much about it, but I am thinking of the standard Q&A approach found here, and ask GPT-3 to summarize in some way that will preserve the tone. Where the data embedded is a bunch of things that person would say/think/believe.
