Can I run SpatialLM1.1 Qwen 0.5B on a Mac?

SpatialLM1.1 Qwen 0.5B requires at least 1.5 GB at BF16, 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 SpatialLM1.1 Qwen 0.5B locally?

Yes — SpatialLM1.1 Qwen 0.5B can run locally on consumer hardware. At BF16 quantization it needs 1.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is SpatialLM1.1 Qwen 0.5B?

At BF16, SpatialLM1.1 Qwen 0.5B can reach ~1905 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~428 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 ÷ 1.5 × 0.55 = ~1905 tok/s

Estimated speed at BF16 (1.5 GB)

~1905 tok/s
~428 tok/s
~1424 tok/s
~1178 tok/s

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