Show HN: ChatGPT Bot Trained on Reddit Data

how did you make this - was this done with embeddings? the brute force way (sending all the data as part of a chat context) seems unscalable at your level

btw would love to see this for other subreddits or reddit in general where it weighs certain subreddits more heavily when answering questions tailored towards them

Seems like calling it ChatGPT might be a little misleading, their description implies they fine-tuned another pretrained GPT model, like GPT-2/3/neo or something, which seems fine for this use case

They are matching the query with the document embeddings and summarizing the top few matches.

I'm guessing, only the summarization step makes use of ChatGPT. Calling it a chatbot is slightly misleading. It's more of a question answering system over external documents.
