Can I run Datarus R1 14B Preview on a Mac?

Datarus R1 14B Preview requires at least 8.1 GB at Q4_0, 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 Datarus R1 14B Preview locally?

Yes — Datarus R1 14B Preview can run locally on consumer hardware. At Q4_0 quantization it needs 8.1 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Datarus R1 14B Preview?

At Q4_0, Datarus R1 14B Preview can reach ~360 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~81 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 ÷ 8.1 × 0.55 = ~360 tok/s

Estimated speed at Q4_0 (8.1 GB)

~360 tok/s
~81 tok/s
~269 tok/s
~223 tok/s

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