DGX Spark vs Framework Desktop vs Mac Studio — house model 2026

I want one box that the family can hit via Open WebUI and that I can fine-tune on without a cloud bill. Spark is the object I want. Studio is the object I will not hear. Framework is the object I can fix. Talk me out of buying all three.

If CUDA/NIM matters, Spark. If you already live in macOS, Studio. If you want the same APU as every mini-PC video plus screws you can turn, Framework. Do not buy three. Buy the one that matches the software you already know how to restart at 1 a.m.

Studio + MLX is still the least annoying 70B in a living room. Spark is the flex. Both are correct. The mini-PC with 32 GB is not a house model, it is a demo.
