This says "We provide an Instruct model of similar quality to text-davinci-003", but two paragraphs later says the output is comparable to Stanford's Alpaca. Those seem like very different claims.
"We performed a blind pairwise comparison between text-davinci-003 and Alpaca 7B, and we found that these two models have very similar performance: Alpaca wins 90 versus 89 comparisons against text-davinci-003."
