Frequently Asked Questions
- How much VRAM does Supergemma4 E4b Abliterated need?
Supergemma4 E4b Abliterated requires 5.0 GB of VRAM at Q4_K_M, or 15.6 GB at BF16. Full 131K context adds up to 13.9 GB (18.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.5B × 4.8 bits ÷ 8 = 4.5 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 14.4 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M5.0 GBQ4_K_M + full context18.9 GB- What's the best quantization for Supergemma4 E4b Abliterated?
For Supergemma4 E4b Abliterated, Q4_K_M (5.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (5.9 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.7 GB.

- Can I run Supergemma4 E4b Abliterated on a Mac?
Supergemma4 E4b Abliterated requires at least 3.7 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 Supergemma4 E4b Abliterated locally?
Yes — Supergemma4 E4b Abliterated can run locally on consumer hardware. At Q4_K_M quantization it needs 5.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Supergemma4 E4b Abliterated?
At Q4_K_M, Supergemma4 E4b Abliterated can reach ~875 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~130 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 5.0 × 0.65 = ~1034 tok/s
Estimated speed at Q4_K_M (5.0 GB)
~1034 tok/s~130 tok/s~1034 tok/s~875 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Supergemma4 E4b Abliterated?
