Frequently Asked Questions
Is LLaMA available for commercial use?
Meta released LLaMA under an academic‑only license; commercial use requires a license or alternative models like Alpaca are open for commercial deployment.
Can Alpaca be fine‑tuned for medical text?
Yes, Alpaca’s instruction‑tuned design makes it straightforward to fine‑tune on specialized corpora, including medical literature.
Which model runs better on a laptop with 8GB RAM?
Alpaca’s 7B size can be accommodated with quantization on such hardware, whereas LLaMA’s larger variants would struggle.
Do I need a GPU to run these models?
Both can run on CPU, but inference will be significantly faster with a GPU; Alpaca’s smaller size is more CPU‑friendly.
