This might be an interesting language model. However people care about ChatGPT entirely due to its quality, which this doesn’t demonstrate yet.
The leap in public exposure wasn't so much GPT3 to GPT3.5, it was attaching a clean UI to the model, (with sane defaults) and allowing people to talk to it like a person. Suddenly it became something 'real' then. (This is purely talking about the public popularity of GPT)
I had wired up GPT3 to a Twilio phone number and made something basically like ChatGPT months before ChatGPT was released -- me and my friends texted it all the time to get information, similar to how people use ChatGPT. The prompt to get decent performance is super simple. Just something like:
The following is a transcript between a human and a helpful AI assistant.
The AI assistant is knowledgeable about most facts of the world and provides concise answers to questions.

The next thing the assistant says is:
Over time I did upgrade the prompt a bit to improve performance for specific kinds of queries, but nothing crazy.Cost me $10-20/mo to run for the low/moderate use by me and a few friends.
Interestingly, for people who didn't know its limitations / how to break it, it was basically passing the turing test. ChatGPT is inhumanly wordy, whereas GPT3 can actually be much more concise when prompted to do so. If, instead of prompting it that it is an AI assistant, you prompt it that it is a close friend with XYZ personality traits, it does a very good job of carrying on a light SMS conversation.
