What problem does it solve?

This Skill helps you configure, train, evaluate, and deploy large language models with Axolotl without getting lost in complex setup details. It reduces the friction of working with dataset formats, adapter tuning, distributed training, and post-training workflows.

Core Features & Use Cases

  • Model Fine-Tuning: Set up SFT, LoRA, QLoRA, DPO, KTO, ORPO, GRPO, and related training flows.
  • Dataset Handling: Prepare pretraining, conversation, instruction, template-free, and pre-tokenized datasets correctly.
  • Operational Workflows: Support preprocessing, inference, quantization, merging, evaluation, and multimodal training scenarios.
  • Use Case: A team can take an existing Hugging Face model, point Axolotl at a custom YAML config and dataset, then run a repeatable fine-tuning pipeline with clear validation steps.

Quick Start

Ask for an Axolotl configuration tailored to your model, dataset format, and training goal so you can launch a correct fine-tuning run immediately.

Frequently Asked Questions about axolotl

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure YAML for fine-tuning a large language model with LoRA or QLoRA?

To configure YAML for LoRA or QLoRA fine-tuning, you define valid training parameters, supported model and tokenizer options, and dataset formats within the config. This translates your training goals into correct operational steps for a repeatable pipeline.

Can I use DPO, KTO, ORPO, and GRPO for RLHF post-training in an Axolotl workflow?

Yes, DPO, KTO, ORPO, and GRPO are supported RLHF post-training flows. You can set up these training scenarios by providing appropriate YAML settings and post-training parameters to guide the large language model alignment process.

How do I prepare pretraining, conversation, and instruction datasets for LLM fine-tuning?

Preparing pretraining, conversation, instruction, template-free, and pre-tokenized datasets requires correct formatting and preprocessing steps. Valid dataset formatting ensures the YAML config accurately maps training data to the model during fine-tuning.

Does this workflow support multimodal training and model quantization?

Yes, multimodal training and quantization are supported operational workflows. You can configure these scenarios using valid YAML settings alongside appropriate training parameters to process and compress large language models.

What's the best way to merge adapters and run inference after fine-tuning a model?

The best way to merge adapters and run inference is by following the supported post-training operational workflows. Using valid YAML settings, you can execute merging, evaluation, and inference steps to validate and deploy your fine-tuned model.

Axolotl fine-tuning is not working, what YAML settings and prerequisites do I need?

Axolotl fine-tuning requires valid YAML settings, supported model and tokenizer options, and appropriate training parameters. Ensure your dataset formatting matches the expected preprocessing requirements to complete each workflow successfully.
