In formal analogies, : is pronounced "is to" and :: is pronounced "as".

The purpose here is to use the relationship from a known, to describe the relationship between a partial known.

ChatGPT is to GPT3 as ChatLLaMa is to LLaMa. It uses the relationship between ChatGPT and GPT3 to extrapolate a relationship between an unknown and LLaMa.

Corolla:Toyota::3-Series:BMW. If you had heard of a Corolla, Toyota, and BMW, but not a 3-Series, you now roughly know that a 3-Series is BMWs equivalent to a Corolla.

I think I prefer the other commenter's point, referring to ChatGPT as a known learning paradigm for chatbots. But thanks for the little crash course on analogies ;)

Isn't that consistent with, and the same as, my original comment?

ChatGPT:GPT3::ChatLLaMa:LLaMa::Chatbot-through-RLHF:LLM

aka ChatGPT is a known chatbot implementation, and GPT3 and LLaMa are known LLMs.

Yes and no. You wouldn't say GPT to mean large language models or autoregressive language models. I would've thought the same to be true for ChatGPT instead of Chatbots with RL from human feedback (RLHF), perhaps the field is moving towards adopting ChatGPT as a paradigm name. Note that the title doesn't say a ChatGPT-like model based on LLaMa, it says outright opensource implementation of ChatGPT.

In the analogy, that’s exactly what you are saying. Identical to Toyota and BMW meaning “the make of the car.”

Maybe reimplementation is a more precise word, a black box re-engineering/cloning. In this case I inferred it by knowing it was a different LLM underneath, and that this group didn’t have access to the chatgpt source code.
