Can I run Gemma 2 9B IT Abliterated on a Mac?

Gemma 2 9B IT Abliterated requires at least 3.7 GB at IQ2_XS, 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 2 9B IT Abliterated locally?

Yes — Gemma 2 9B IT Abliterated can run locally on consumer hardware. At Q4_K_M quantization it needs 6.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Gemma 2 9B IT Abliterated?

At Q4_K_M, Gemma 2 9B IT Abliterated can reach ~451 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~101 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 MI300X5300 ÷ 6.5 × 0.55 = ~451 tok/s

Estimated speed at Q4_K_M (6.5 GB)

~451 tok/s
~101 tok/s
~337 tok/s
~279 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
