Frequently Asked Questions

How much VRAM does Supra 50M Reasoning need?

Supra 50M Reasoning 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.

Can I run Supra 50M Reasoning on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Supra 50M Reasoning. 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 50M Reasoning locally?

Yes — Supra 50M Reasoning can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Supra 50M Reasoning?

At Q4_K_M, Supra 50M Reasoning 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
