Can I run Inkling Small on a Mac?

Inkling Small requires at least 73.8 GB at IQ2_XXS, 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 Inkling Small locally?

Yes — Inkling Small can run locally on consumer hardware. At Q4_K_M quantization it needs 160.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Inkling Small?

At Q4_K_M, Inkling Small can reach ~30 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B2008000 ÷ 160.2 × 0.65 = ~33 tok/s
