Tested on a M3 Ultra 512GB RAM using Inferencer app v1.10.11

• Single inference ~14.17 tokens/s @ 1000 tokens (debug build)
• Batched inference ~ total tokens/s across two inferences
• Memory usage: ~419.30 GiB

Q4.8-INF typically achieves near lossless accuracy in our coding test, using the data-agnostic INF method tuned to fit within a 512GB memory budget

• 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
