Gemma 4 E2B in MLX format, full bf16 precision, converted from LetheanNetwork/lemer's bf16 safetensors via mlx_lm.convert --dtype bfloat16. No quantization — this is the full-precision reference for the MLX family. For smaller / faster variants see LetheanNetwork/lemer-mlx (4-bit) or LetheanNetwork/lemer-mlx-8bit. For the LEK-merged variant see lthn/lemer.

Usage

python

from mlx_lm import load, generate

model, tokenizer = load("LetheanNetwork/lemer-mlx-bf16")

        [{"role": "user", "content": "Hello"}],
        add_generation_prompt=True,
