gemma-4-12B-it MLX 4-bit

This repository contains an MLX-LM conversion of google/gemma-4-12B-it.

Conversion Details

• Original model: google/gemma-4-12B-it
• Model family: Gemma4
• Source model type: gemma4_unified
• Model size: 11,959,730,224 parameters
• Quantization: MLX-LM affine quantization
• Bits: 4-bit
• Group size: 64
• Local MLX folder size at upload time: 6.27 GiB
• Local safetensors weight size at upload time: 6.24 GiB

This Gemma conversion follows the MLX-LM Gemma 4 shared-KV topology and uses non-strict checkpoint loading so extra HF tensors outside that topology are discarded during conversion.

The temporary conversion config remapped gemma4_unified to gemma4 because this mlx-lm build exposes that Gemma 4 implementation.

Usage

mlx_lm.generate --model DreamFoundries/gemma-4-12B-it-4bit --prompt "Hello" --max-tokens 64

Benchmarks

No comparative benchmarks have been run yet. The repository does not currently provide quality, speed, memory, or benchmark comparisons against the original weights or other quantizations.
