Before it
Instruction tuning was assumed to need industrial resources and proprietary data.
The problem
Could a university group turn a base model into an assistant for pocket change?
What it introduced
52,000 self-instruct examples generated from text-davinci-003, used to fine-tune LLaMA 7B for a few hundred dollars.
Why it matters
It showed capability could be distilled cheaply from a stronger model, which set off the open fine-tune explosion and the licensing fights.
What modern models inherit
Cheap instruction tuning by distilling from a stronger model.
What came next
Vicuna and dozens of derivatives; distillation became standard practice and a terms-of-service problem.
