Claims

C1strongest claim

With our efficient training, LLaMA-Adapter can generate high-quality responses, comparable to Alpaca with fully fine-tuned 7B parameters.

C2weakest assumption

The zero-initialized attention mechanism with zero gating adaptively injects the new instructional cues into LLaMA while effectively preserving its pre-trained knowledge.

C3one line summary

LLaMA-Adapter turns frozen LLaMA 7B into a capable instruction follower using only 1.2M new parameters and zero-init attention, matching Alpaca while extending to image-conditioned reasoning on ScienceQA and COCO.
