Yup this is for sure not all the outputs, but these are all in sequence, so it's able to output this quality consistently. It's just really good at generating human-like output. I posted a link to a Gist with full playground file in one of the other comments here, that included both my seed prompts at the top and then all the OpenAI answers below.

Regardless, maybe I or someone else can create a post with a random set of questions / answers to show a more unbiased view of the GPT-3 outputs.
