gemma-4-31B-it-oQ4e-mtp

Updated 2026-10-29: Re-quantized with the improved oQe quantization in oMLX 0.7.3. Please re-download if you have an earlier copy.

This model was quantized using oQ (oMLX v0.7.3) mixed-precision quantization with improved oQe (jundot/omlx#4930).

A mixed-precision MLX checkpoint of google/gemma-4-31B-it, the 30.7B dense model of the Gemma 4 family from Google DeepMind, with text and image input, configurable thinking modes and a 256K-token context. It includes the language model, the vision encoder and a multi-token prediction (MTP) head merged from google/gemma-4-31B-it-assistant.

The effective average is 4.801 bits/weight for the language backbone and 5.167 bits/weight for the complete checkpoint.

Quantization and Bit Distribution

oQ4e allocates bits by measured layer sensitivity, then rounds each group with an importance matrix (128 samples x 512 tokens) and a weighted least-squares refit of its scale and bias.

Storage format	Logical weights	Share of total	Tensor storage	Effective bits/weight
Affine 4-bit, group 64	21.790B	68.645%	11.415 GiB	4.50
Affine 5-bit, group 64	8.615B	27.141%	5.516 GiB	5.50
Affine 6-bit, group 64	0.297B	0.937%	0.225 GiB	6.50
BF16	1.040B	3.278%	1.938 GiB	16.00
Total	31.743B	100%	19.094 GiB	5.167
