Frequently Asked Questions
How much VRAM does Supra Router 51M need?
Supra Router 51M requires 0.4 GB of VRAM at Q4_K_M, or 0.4 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 52M × 4.8 bits ÷ 8 = 0 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 0.4 GB (at full 5K context)
VRAM usage by quantization
What's the best quantization for Supra Router 51M?
For Supra Router 51M, Q4_K_M (0.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.4 GB) provides better quality if you have the VRAM. The smallest option is Q4_0 at 0.3 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Supra Router 51M on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Supra Router 51M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.4 GB of usable unified memory (RAM minus macOS overhead).
Can I run Supra Router 51M locally?
Yes — Supra Router 51M can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Supra Router 51M?
At Q4_K_M, Supra Router 51M can reach ~13333 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1820 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 ÷ 0.36 × 0.65 = ~14444 tok/s
Estimated speed at Q4_K_M (0.4 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Supra Router 51M?
At Q4_K_M, the download is about 0.03 GB. The full-precision BF16 version is 0.10 GB. The smallest option (Q4_0) is 0.03 GB.
Which GPUs can run Supra Router 51M?
52 consumer GPUs can run Supra Router 51M at Q4_K_M. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 52 GPUs have plenty of headroom for comfortable inference.
Which devices can run Supra Router 51M?
163 devices with unified memory can run Supra Router 51M at Q4_K_M (0.4 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB).
