FAQPage Schema
How do I configure a YAML file for LLM fine-tuning with LoRA or QLoRA?

To configure LLM fine-tuning, you specify YAML frontmatter to define dataset paths, prompt templates, and LoRA/QLoRA parameters. This setup guides the training pipeline by referencing official documentation and example configurations for efficient PEFT execution.

What's the best way to set up RLHF or DPO training workflows for large language models?

Setting up RLHF or DPO training workflows involves using guided steps to define preference datasets and reward models. The process supports various alignment techniques including DPO, KTO, ORPO, and GRPO to steer model behavior effectively across different hardware setups.

Can I use this approach for multimodal fine-tuning across different hardware environments?

Yes, multimodal fine-tuning is supported across various hardware environments and model sizes. You can configure training pipelines that handle diverse data inputs by referencing official documentation and specific API references for cross-platform compatibility.

How do I start fine-tuning an LLM when I only have a raw dataset and prompt templates?

Start fine-tuning an LLM by configuring a single guided setup that maps your raw datasets and prompt templates into a structured YAML format. This references official examples to initialize the training and evaluation pipeline for your specific model.

Does this fine-tuning workflow support SFT and evaluation pipelines end to end?

Yes, the fine-tuning workflow supports SFT and evaluation pipelines end to end. Step-by-step guidance covers the entire lifecycle from initial environment setup and experimentation through to final model evaluation using official reference files.

What are the limitations of using PEFT methods like QLoRA for large language model training?

PEFT methods like QLoRA optimize memory but may limit full parameter expressiveness during large language model training. Constraints depend on your specific hardware scale and dataset structure, requiring careful YAML configuration to balance efficiency and model performance.
