The paper "LLaMA-Adapter: Efficient Fine-tuning of Language Models with Zero-init Attention" presents a lightweight adaptation method for fine-tuning the LLaMA language model using self-instruct demonstrations and a zero-init attention mechanism with zero gating, achieving high-quality responses comparable to Alpaca with fully fine-tuned 7B parameters in less than one hour on 8 A100 GPUs, and can be extended to multi-modal input for superior reasoning capacity on ScienceQA.

Key insights and lessons learned:

• LLaMA-Adapter is an efficient and effective method for fine-tuning LLaMA language model with minimal learnable parameters and training time, using self-instruct demonstrations and zero-init attention mechanism with zero gating.
• LLaMA-Adapter generates high-quality responses comparable to Alpaca with fully fine-tuned 7B parameters, while preserving the pre-trained knowledge of LLaMA.
• LLaMA-Adapter can be extended to multi-modal input for superior reasoning capacity on ScienceQA.
• The method and code of LLaMA-Adapter are publicly available for further research and applications.
