Frequently Asked Questions

What is the cost of using LLaMA Factory?▾
LLaMA Factory is completely free and open-source. You only pay for computing resources (cloud instances or local hardware) needed to run the fine-tuning process.
How difficult is it to get started with LLaMA Factory?▾
Setup is straightforward thanks to the included web UI—no coding required for basic configuration. However, optimizing training parameters and handling distributed setups may require some technical knowledge.
What models and integrations does LLaMA Factory support?▾
LLaMA Factory is compatible with 100+ open-source language models and integrates with popular frameworks. It can work with Hugging Face model hub and supports multi-GPU setups across different hardware configurations.
What is the main limitation of LLaMA Factory?▾
It requires local hardware or cloud compute resources to run fine-tuning jobs, making it unsuitable for users without access to GPUs or technical infrastructure. Full-scale training can still be resource-intensive despite parameter-efficient methods.
What is LLaMA Factory best used for?▾
It's ideal for fine-tuning open-source language models on limited budgets using LoRA/QLoRA techniques that fit on consumer GPUs. It works well for domain-specific model adaptation, research projects, and teams wanting full control over model training.
