- Can I run Qwen3 8B Abliterated on a Mac?
Qwen3 8B Abliterated requires at least 3.8 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 Qwen3 8B Abliterated locally?
Yes — Qwen3 8B Abliterated can run locally on consumer hardware. At Q4_K_M quantization it needs 5.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwen3 8B Abliterated?
At Q4_K_M, Qwen3 8B Abliterated can reach ~813 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~121 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 ÷ 5.4 × 0.65 = ~961 tok/s
Estimated speed at Q4_K_M (5.4 GB)
~961 tok/s~121 tok/s~961 tok/s~813 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
