Frequently Asked Questions
- How much VRAM does SKT ST X 0 3B need?
SKT ST X 0 3B requires 2.4 GB of VRAM at Q4_K_M, or 7.1 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 3.4B × 4.8 bits ÷ 8 = 2 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q4_K_M2.4 GB- What's the best quantization for SKT ST X 0 3B?
For SKT ST X 0 3B, Q4_K_M (2.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (2.8 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.8 GB.

- Can I run SKT ST X 0 3B on a Mac?
SKT ST X 0 3B requires at least 1.8 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 SKT ST X 0 3B locally?
Yes — SKT ST X 0 3B can run locally on consumer hardware. At Q4_K_M quantization it needs 2.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is SKT ST X 0 3B?
At Q4_K_M, SKT ST X 0 3B can reach ~1849 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~275 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 ÷ 2.4 × 0.65 = ~2185 tok/s
Estimated speed at Q4_K_M (2.4 GB)
~2185 tok/s~275 tok/s~2185 tok/s~1849 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of SKT ST X 0 3B?
