Frequently Asked Questions
How much VRAM does Supra 1.5 50M Instruct Exp need?
Supra 1.5 50M Instruct Exp 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 1.5 50M Instruct Exp?
For Supra 1.5 50M Instruct Exp, 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 Q2_K at 0.3 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Supra 1.5 50M Instruct Exp on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Supra 1.5 50M Instruct Exp. 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 1.5 50M Instruct Exp locally?
Yes — Supra 1.5 50M Instruct Exp can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Supra 1.5 50M Instruct Exp?
At Q4_K_M, Supra 1.5 50M Instruct Exp 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 1.5 50M Instruct Exp?
At Q4_K_M, the download is about 0.03 GB. The full-precision BF16 version is 0.10 GB. The smallest option (Q2_K) is 0.02 GB.
