8 years of cost reduction in 5 weeks: how Stanford’s Alpaca model changes everything, including the economics of OpenAI and GPT 4. The breakthrough, using self-instruct, has big implications for Apple’s secret large language model, Baidu’s ErnieBot, Amazon’s attempts and even governmental efforts, like the newly announced BritGPT.
I will go through how Stanford put the model together, why it costs so little, and demonstrate in action versus Chatgpt and GPT 4. And what are the implications of short-circuiting human annotation like this? With analysis of a tweet by Eliezer Yudkowsky, I delve into the workings of the model and the questions it rises.

Eliezer Tweet:
I don’t think people realize what a big deal it is that Stanford retrained a LLaMA model, into an instruction-following form, by **cheaply** fine-tuning it on inputs and outputs **from text-davinci-003**.
It means: If you allow any sufficiently wide-ranging access to your AI…

Dear silly Internet saying “but knowledge distillation is already known”: the key idea here is that the fine-tuning above the base model is comparatively much *easier* and *cheaper* to extract and re-imbue, if you have a new base comparable to the earlier base model.
