- Can I run Japanese GPT Neox Small on a Mac?
Japanese GPT Neox Small requires at least 0.1 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 Japanese GPT Neox Small locally?
Yes — Japanese GPT Neox Small can run locally on consumer hardware. At Q4_K_M quantization it needs 0.1 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Japanese GPT Neox Small?
At Q4_K_M, Japanese GPT Neox Small can reach ~36923 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~5040 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 ÷ 0.1 × 0.65 = ~40000 tok/s
Estimated speed at Q4_K_M (0.1 GB)
~40000 tok/s~5040 tok/s~40000 tok/s~36923 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
