How to Fine-Tune LLMs with Axolotl on RunPod

Axolotl provides tools for fine-tuning language models (LLMs) using pre-trained weights and frameworks like Hugging Face Transformers, while RunPod offers scalable GPU cloud servers ideal for high-resource LLM fine-tuning tasks. The tutorial guides users in setting up Axolotl on RunPod, covering prerequisites like a high-end GPU, RunPod account, and proficiency in Linux commands, Python, and model fine-tuning principles. It details selecting suitable RunPod instances based on model size and budget, installing Axolotl, preparing data, and configuring Axolotl with YAML files. The process involves using efficient training methods, such as 8-bit quantization and LoRA adapters, and emphasizes monitoring training progress using tools like Weights & Biases and TensorBoard. The guide concludes with tips for optimizing efficiency and costs, such as choosing the right instance size, employing LoRA and quantization techniques, and considering spot instances for non-critical jobs.
