Alpaca is not as cheap as you think
"Alpaca is just $100 and competitive with InstructGPT" -- takes like this are going around Twitter, adding to the (generally justified!) hype around AI models.
It is indeed a very encouraging result. Specifically, that it took so little compute to train something that achieves competitive results on benchmarks and is a relatively small model at 7B parameters. I haven't seen yet a demo that would show Alpaca do well in an application (like Jasper), but that might not be far off.
If they had created the labels on their own, the 52k-example dataset would have cost much more than $100. Assuming a human labeller can write one example in 3 minutes, at $10/hr the cost of the dataset would be $26k. That is still cheap relative to e.g. training GPT-3 from scratch (~$500k), but far from the $100 that most hackers would be willing to pay.
Grumbling aside, I am glad to see Llama getting hacked and ported and optimized. It's encouraging to see that the open-source community can make wild and creative progress. Perhaps it's like with the Fosbury flop or 4-minute mile: once OpenAI has demonstrated something is possible, this proof of existence motivates the OSS community to achieve great things.
