How do I deploy a LoRA-trained model?

You can either load the small adapter weights at runtime using the PEFT library or merge the LoRA weights directly into the base model for a standalone production deployment.

Does this skill support QLoRA?

Yes, it includes detailed patterns and configurations for 4-bit quantization (QLoRA), enabling the fine-tuning of large models like Llama 3 on limited VRAM.

Can I use multiple adapters simultaneously?

Yes, the skill provides implementation patterns for loading, switching between, and disabling multiple task-specific adapters on a single shared base model.

What is the main benefit of using LoRA over full fine-tuning?

LoRA drastically reduces memory and storage requirements by training only ~0.1% of the model's parameters, allowing for faster training and the ability to run on consumer hardware while maintaining performance.

Which model architectures are supported?

The skill provides target module configurations for major transformer architectures including Llama, Mistral, Qwen, GPT-2, BERT, RoBERTa, Falcon, and Phi.
