FAQPage Schema
How do I fine-tune a Large Language Model on custom documentation?

Fine-tuning a Large Language Model on custom documentation requires preparing a JSONL dataset, selecting a PEFT method like LoRA, and configuring hyperparameters. This Skill streamlines that process by providing tools for dataset validation, adapter training, and deployment.

What is the difference between LoRA and QLoRA for model training?

LoRA and QLoRA are both Parameter-Efficient Fine-Tuning methods for model training. QLoRA incorporates quantization to reduce memory usage during adapter training, while standard LoRA updates low-rank matrices without quantizing the base model weights.

Can I use QLoRA for instruction tuning on a quantized base model?

Yes, you can use QLoRA for instruction tuning on a quantized base model. QLoRA is specifically designed to enable adapter training and fine-tuning on quantized Large Language Models, optimizing memory usage while maintaining performance.

How do I prepare a JSONL dataset for LLM fine-tuning?

Preparing a JSONL dataset for LLM fine-tuning involves formatting your custom text or instruction pairs into a structured JSON Lines format. This Skill validates and formats the training data to ensure optimal model performance during the fine-tuning process.

What hyperparameters should I tune for PEFT implementation?

For PEFT implementation, you should tune hyperparameters including learning rates, batch sizes, and schedulers. Proper hyperparameter tuning is crucial for optimizing adapter training and ensuring the fine-tuned model converges effectively.

When should I not use full fine-tuning instead of PEFT methods?

You should not use full fine-tuning when computational resources are limited or when adapting a Large Language Model for specific tasks. PEFT methods like LoRA and QLoRA train adapters efficiently, avoiding the need to update all model parameters.
