Frequently Asked Questions
- How much VRAM does Qwen3.6 28B need?
Qwen3.6 28B requires 17.3 GB of VRAM at Q4_K_M, or 56.9 GB at BF16. Full 262K context adds up to 10.7 GB (28.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 28.2B × 4.8 bits ÷ 8 = 16.9 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11.1 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M17.3 GBQ4_K_M + full context28.0 GB- Can NVIDIA GeForce RTX 4090 run Qwen3.6 28B?
Yes, at Q6_K (23.7 GB) or lower. Higher quantizations like Q8_0 (28.6 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen3.6 28B?
For Qwen3.6 28B, Q4_K_M (17.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (20.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 12.4 GB.

- Can I run Qwen3.6 28B on a Mac?
Qwen3.6 28B requires at least 12.4 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Qwen3.6 28B locally?
Yes — Qwen3.6 28B can run locally on consumer hardware. At Q4_K_M quantization it needs 17.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwen3.6 28B?
At Q4_K_M, Qwen3.6 28B can reach ~254 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~38 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 ÷ 17.3 × 0.65 = ~300 tok/s
Estimated speed at Q4_K_M (17.3 GB)
~300 tok/s~38 tok/s~300 tok/s~254 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Qwen3.6 28B?
At Q4_K_M, the download is about 16.94 GB. The full-precision BF16 version is 56.48 GB. The smallest option (Q2_K) is 12.00 GB.
- Which GPUs can run Qwen3.6 28B?
