LLaMa-7B output is abysmally horrible. We might need less than 100B, but not too much less.

Exactly, I have seen many inaccurate claims, e.g. LLaMa-7B with Alpaca being as capable as ChatGPT. From my testing even much bigger LLaMa-30B with Alpaca is far worse than ChatGPT, can't even get simplest programming and common knowledge tasks right, and GPT3 ChatGPT get them right without any problems every time. I have not tried LLaMa-65B with Alpaca yet, because it has not being trained yet AFAIK, but I doubt it will be very different. GPT3 ChatGPT is 175B, maybe some 100B model can match it, but not 6B or 7B model, if someone claim this, he clearly don't know what he is talking about.

I believe you might have misunderstood the claims in Alpaca. They never stated it is as capable as ChatGPT, they found (and you can confirm this yourself) that it accurately replicates the instruction tuning. That is, for most of the areas in the fine-tuning set, a smaller model will output in the same style of davinci. And that's an amazing progress from the raw outputs of the raw models.

This is a misleading summary of the paper.

They instruction tune and then compare Alpaca versus GPT-3.5, and say that Alpaca is about equal on the tasks it compares (which, to be clear, is not equivalent to a test of "broad capability").

Yes, you are right that they don't make a statement that it is categorically more capable than ChatGPT, but they do state that their model is approximately as capable as GPT3.5 (which is of course not a 1:1 to chatgpt), on the diverse set of tasks tested.

It is very much not just a paper showing that you can make it output in the same "style".

Yeah, I think there's a lot of overhyping going around "running ChatGPT-grade language models on consumer hardware". They can "follow" instructions they same way as ChatGPT, but obviously those models know far, far less than the ClosedAI models do, and of course they'll hallucinate much more.

Although it's not an entirely bad thing, at least the community will innovate more so we might get something interesting in the future from this "push" :)

OpenAI is also doing a lot of tricks behind the scenes, so it's not really fair to just type two things into both, because they are getting nowhere near the same prompt. Llama is promising but it just needs to be properly instruction tuned

no they is no overhype, you just don't understand what Alpaca is trying to do & I am sure others will also reply similar

My observations are similar to yours, but I think Stanford's claim was that it rivalled text-davinci-003's dialogue or chat capabilities, and only in a single turn setting.
