Right now, all the questions about gpt2-chatbot conflate whether it's a new, improved model with whether it's from OpenAI. Let's break this down - this Q will just focus on whether this model was created by OpenAI. The question will resolve "yes" if it's confirmed before EOY by OpenAI officially.

I will bet in this market myself as I expect the outcome to be relatively clear cut. If it's not clear cut I'll err on the side of N/A to avoid the appearance of bias though.
