Frequently Asked Questions

How much VRAM does Quark 135M need?

Quark 135M requires 0.4 GB of VRAM at Q4_K_M, or 0.6 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 135M × 4.8 bits ÷ 8 = 0.1 GB

KV Cache + Overhead ≈ 0.3 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 Quark 135M on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Quark 135M. 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 Quark 135M locally?

Yes — Quark 135M can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Quark 135M?

At Q4_K_M, Quark 135M can reach ~11163 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1524 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 ÷ 0.43 × 0.65 = ~12093 tok/s
