Frequently Asked Questions
- How much VRAM does SpatialLM1.1 Qwen 0.5B need?
SpatialLM1.1 Qwen 0.5B requires 1.5 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 604M × 16 bits ÷ 8 = 1.2 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 0.7 GB (at full 33K context)
VRAM usage by quantization
BF161.5 GBBF16 + full context1.9 GB- 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 ~2876 tok/s on AMD Instinct MI350X. 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: NVIDIA B200 → 8000 ÷ 1.5 × 0.65 = ~3399 tok/s
Estimated speed at BF16 (1.5 GB)
~3399 tok/s~428 tok/s~3399 tok/s~2876 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
