Frequently Asked Questions
- How much VRAM does Qwopus3.6 27B v2 MLX 4bit need?
Qwopus3.6 27B v2 MLX 4bit requires 54.5 GB of VRAM at BF16. Full 262K context adds up to 56.8 GB (111.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 26.9B × 16 bits ÷ 8 = 53.8 GB
KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 57.6 GB (at full 262K context)
VRAM usage by quantization
BF1654.5 GBBF16 + full context111.4 GB- Can NVIDIA GeForce RTX 5090 run Qwopus3.6 27B v2 MLX 4bit?
No — Qwopus3.6 27B v2 MLX 4bit requires at least 54.5 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run Qwopus3.6 27B v2 MLX 4bit on a Mac?
Qwopus3.6 27B v2 MLX 4bit requires at least 54.5 GB at BF16, 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 Qwopus3.6 27B v2 MLX 4bit locally?
Yes — Qwopus3.6 27B v2 MLX 4bit can run locally on consumer hardware. At BF16 quantization it needs 54.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwopus3.6 27B v2 MLX 4bit?
At BF16, Qwopus3.6 27B v2 MLX 4bit can reach ~53 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 54.5 × 0.55 = ~53 tok/s
Estimated speed at BF16 (54.5 GB)
~53 tok/s~40 tok/s~33 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Qwopus3.6 27B v2 MLX 4bit?
At BF16, the download is about 53.79 GB.
- Which GPUs can run Qwopus3.6 27B v2 MLX 4bit?
No single consumer GPU has enough VRAM to run Qwopus3.6 27B v2 MLX 4bit at BF16 (54.5 GB). Multi-GPU or professional hardware is required.
- Which devices can run Qwopus3.6 27B v2 MLX 4bit?
