Train your own model with Unsloth, an open-source framework for LLM fine-tuning and reinforcement learning.
Machine Learning Tutorial
Summary
The page is a step‑by‑step tutorial for fine‑tuning OpenAI's gpt‑oss models using the Unsloth library. It covers both local and Google Colab workflows, hyperparameter settings, LoRA adapters, and hardware requirements.
Highlights
- Provides a free Colab notebook for quick fine‑tuning of gpt‑oss‑20b and larger models.
- Claims up to 1.5× faster training, 70% less VRAM usage, and 10x longer context lengths versus other FA2 implementations.
- Details hardware requirements for QLoRA (14 GB VRAM) and BF16 LoRA (44 GB VRAM) configurations.
- Explains how to enable 4‑bit loading or full‑precision BF16 mode and adjust max sequence length.
- Includes guidance on monitoring loss, avoiding overfitting, and using LoRA adapters for parameter‑efficient training.
