    How do you fine-tune Qwen with LoRA in the cloud cheaply?

    <p>Fine-tune Qwen cheaply with one LoRA adapter on the smallest single GPU that holds twice the frozen weights: 16-bit LoRA up to about 9B, 4-bit QLoRA for 14B to 32B dense models. Nodus ships single-GPU Qwen3 presets from 0.6B to 8B in its managed <code>nodus/sft</code> runtime,…
