gemma-4-12B-it-qat-q4_0-unquantized Q4_0
This file is exactly 6,975,879,296 bytes — 6.50 GiB / 6.98 GB at an effective 4.666 bits per weight. The nominal rate for Q4_0 is lower; mixed-precision tensors make the real figure higher, always.

What this quantization actually contains
A quantization label names a mixture, not a uniform precision. Attention and output tensors are routinely kept at higher precision than the label implies, which is exactly why the effective bits-per-weight above exceeds the nominal rate.

Quantizing the KV cache to q8_0 is a roughly 2× lever on the dominant term at long context, and it is the single most useful setting most local users never touch. Totals here exclude the allocator reserve your driver takes, which is hardware-specific — the per-accelerator table above includes it.
