Frequently Asked Questions

How much VRAM does Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 need?

Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 requires 1.3 GB of VRAM at Q4_K_M, or 3.5 GB at BF16. Full 41K context adds up to 2.2 GB (3.6 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 1.5B × 4.8 bits ÷ 8 = 0.9 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 ≈ 2.7 GB (at full 41K context)

Can I run Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 1.3 GB of usable unified memory (RAM minus macOS overhead).

Can I run Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 locally?

Yes — Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2?

At Q4_K_M, Qwen3 MOE 4x0.6B 2.4B Writing Thunder V1.2 can reach ~173 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~347 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 0.9 GB active ÷ (8000 × 0.65) = 0.17 ms, plus 28 layers × 0.055 ms = 1.54 ms, so 1000 ÷ 1.71 ms = ~585 tok/s

Estimated speed at Q4_K_M (1.3 GB)

~585 tok/s
~347 tok/s
~585 tok/s
~550 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
