Model comparison
gemma-4-12B-it-qat-q4_0-unquantized vs glm4.1v-9b-base-sft
These two publish different quantization sets; the table below has the exact sizes. At long context the gap widens: glm4.1v-9b-base-sft's KV cache at 32K is 2.0× smaller, which usually matters more than the difference in weights.
