Gemma-4-31B

See gemma-4-31B in action: demonstration video

For improved performance, download and enable a compatible MTP speculative decoder.

Tested on a M3 Ultra 512GB RAM using Inferencer app

Text inference: ~17.1 tokens/s @ 1000 tokens (debug build)
Vision inference: ~15.7 tokens/s
Vision inference: (with MTP): ~34 tokens/s (available from v1.11.5)
Memory usage: ~33.1 GiB

9bpw quant typically achieves near lossless accuracy in our coding test

Quantization (bpw)	Perplexity	Token Accuracy	Missed Divergence
q4.5	1.32812	90.5%	26.44%
q5.5	1.23437	95.4%	16.03%
q6.5	1.21875	96.85%	12.55%
q8.5	1.21875	97.65%	9.92%
q9	1.21093	97.95%	9.61%
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
