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

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.
