How to Fine-Tune Qwen3 on One GPU

We just released a new guide on training the Qwen3 model. You can run this entire process on a single GPU using Google Colab. It shows you how to set up your environment and get the hardware ready for work.
Our tutorial covers the full process from start to finish. We explain how to adjust settings like batch size and precision so the model fits in your memory. We also include a step by step guide on using the command line to launch your training.
After training, you can reload your new weights to compare them against the original model. We show you how to use the Python API to test your results. Check out the full guide to start customizing your own AI models today.
