Frequently Asked Questions
- How much VRAM does Gemma 4 12B OBLITERATED need?
Gemma 4 12B OBLITERATED requires 8.2 GB of VRAM at Q4_K_M, or 13.0 GB at Q8_0. Full 131K context adds up to 47.6 GB (55.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 12.0B × 4.8 bits ÷ 8 = 7.2 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 48.6 GB (at full 131K context)

- Can I run Gemma 4 12B OBLITERATED on a Mac?
Gemma 4 12B OBLITERATED requires at least 6.1 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Gemma 4 12B OBLITERATED locally?
Yes — Gemma 4 12B OBLITERATED can run locally on consumer hardware. At Q4_K_M quantization it needs 8.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Gemma 4 12B OBLITERATED?
At Q4_K_M, Gemma 4 12B OBLITERATED can reach ~354 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~80 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 8.2 × 0.55 = ~354 tok/s
Estimated speed at Q4_K_M (8.2 GB)
~354 tok/s~80 tok/s~265 tok/s~219 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Gemma 4 12B OBLITERATED?
