NVIDIA sent DGX Spark to blogger kimmonismus, who shared a first look: 15×15×5.05cm, 1.2kg, powered by the GB10 Grace Blackwell Superchip with 128GB unified CPU/GPU memory and up to 1 petaflop theoretical FP4 sparse compute. NVIDIA claims it can run models up to 200B parameters locally with quantization and fine-tune up to 70B using methods like QLoRA — enabling local fine-tuning, custom image generation, and locally running AI assistants. Hands-on demos to follow.
