Frequently Asked Questions

How much VRAM does Qwopus3.6 27B v2 need?

Qwopus3.6 27B v2 requires 56.3 GB of VRAM at BF16. Full 262K context adds up to 13.9 GB (70.2 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 27.8B × 16 bits ÷ 8 = 55.6 GB

KV Cache + Overhead ≈ 0.7 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 ≈ 14.6 GB (at full 262K context)

Can NVIDIA GeForce RTX 5090 run Qwopus3.6 27B v2?

No — Qwopus3.6 27B v2 requires at least 56.3 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

Can I run Qwopus3.6 27B v2 on a Mac?

Yes — Mac Pro M2 Ultra (64 GB) and 41 other Macs can run Qwopus3.6 27B v2. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 56.3 GB of usable unified memory (RAM minus macOS overhead).

Can I run Qwopus3.6 27B v2 locally?

Yes — Qwopus3.6 27B v2 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwopus3.6 27B v2?

At BF16, Qwopus3.6 27B v2 can reach ~85 tok/s on AMD Instinct MI350X. 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 ÷ 56.3 × 0.65 = ~92 tok/s
