For 7-billion-parameter models, a single consumer GPU with 16 to 24 gigabytes of VRAM is enough for quantized inference. For 70-billion-parameter models, you need either multiple consumer GPUs or one professional GPU like an H100. For 400-billion-parameter and larger models, you need multi-GPU servers with high-bandwidth interconnects like NVLink or InfiniBand.
