See NVIDIA-Nemotron-3-Super-120B-A12B MLX in action - demonstration video

Tested on a M3 Ultra 512GB RAM using Inferencer app v1.10.6

• Single inference ~49.6 tokens/s @ 1000 tokens
• Batched inference ~ total tokens/s across five inferences
• Memory usage: ~67 GiB

q4.5bit quant targets 96GB RAM devices and typically achieves 91.65% accuracy in our coding test

q9	1.21093	97.55%	10.50%
Base	1.20312	100.0%	0.000%

• Perplexity: Measures the confidence for predicting base tokens (lower is better)
• Token Accuracy: The percentage of correctly generated base tokens
• Missed Divergence: Measures severity of misses; how much the token was missed by

Quantized with a modified version of MLX
