Fine-Tuning Qwen3 with LoRA Using NVIDIA NeMo AutoModel: A Complete Single-GPU Google Colab Workflow Tutorial

A tutorial demonstrates fine-tuning the Qwen3-0.6B large language model using LoRA with NVIDIA NeMo AutoModel on a single GPU in Google Colab. The workflow covers installation, configuration, and execution via the automodel CLI and Python API, enabling efficient adaptation of the model for custom tasks.

We build an end-to-end NVIDIA NeMo AutoModel workflow in Google Colab using a single GPU. We verify CUDA hardware and precision support, install NeMo AutoModel from source, and load an official Qwen3-0.6B LoRA recipe. We then adapt its precision, batch size, checkpointing, and scheduler settings for a constrained runtime. We launch fine-tuning through the automodel CLI, reload the LoRA checkpoint, and compare base versus fine-tuned outputs. We finish with the NeMoAutoModelForCausalLM Python API.
