Bing Chat uses a better model than ChatGPT which results in better written stories. Biggest improvement is I don't have to tell Bing Chat not to start the story with "Once upon a time." It's now at the level of an intelligent 8 year old fan fiction writer that needs to write their story as fast as possible because it's almost bed time. https://pastebin.com/G8iTJmqk

Every time they improve the model it becomes a better writer. I remember when AI Dungeon had the original GPT-3 and it could not stay on topic, and that was fine tuned on stories.
