Frequently Asked Questions
- How much VRAM does S1.1 32B need?
S1.1 32B requires 66.4 GB of VRAM at BF16. Full 33K context adds up to 8.1 GB (74.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 32.8B × 16 bits ÷ 8 = 65.5 GB
KV Cache + Overhead ≈ 0.9 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 8.9 GB (at full 33K context)
VRAM usage by quantization
BF1666.4 GBBF16 + full context74.4 GB- Can NVIDIA GeForce RTX 5090 run S1.1 32B?
No — S1.1 32B requires at least 66.4 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run S1.1 32B on a Mac?
S1.1 32B requires at least 66.4 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 S1.1 32B locally?
Yes — S1.1 32B can run locally on consumer hardware. At BF16 quantization it needs 66.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is S1.1 32B?
At BF16, S1.1 32B can reach ~44 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 66.4 × 0.55 = ~44 tok/s
Estimated speed at BF16 (66.4 GB)
AMD Instinct MI300X~44 tok/sNVIDIA H100 SXM~33 tok/sAMD Instinct MI250X~27 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of S1.1 32B?
At BF16, the download is about 65.53 GB.
- Which GPUs can run S1.1 32B?
No single consumer GPU has enough VRAM to run S1.1 32B at BF16 (66.4 GB). Multi-GPU or professional hardware is required.
- Which devices can run S1.1 32B?
5 devices with unified memory can run S1.1 32B at BF16 (66.4 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio M2 Ultra (192 GB), Mac Studio M4 Max (128 GB), NVIDIA DGX A100 640GB. Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
