Qwen 3.6 27B — VRAM, Speed & Local Setup

Written by Jakub Rusinowski · Last updated April 22, 2026

Model library → Qwen 3.6 → Qwen 3.6 27B

Dense successor to Qwen 3.5 27B with the same hybrid Gated DeltaNet/attention architecture (64 layers) but improved coding benchmarks. Fits a single RTX 3090/4090 at Q4_K_M (~16.8 GB). Apache 2.0, ~256K context extensible to ~1M.

Qwen 3.6 27B needs about 18 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

VRAM and Speed by Quantization

Modelled on a reference NVIDIA RTX 4090 (24 GB), with no KV cache (this record has no published architecture). Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.

Qwen 3.6 27B — Frequently Asked Questions

How much VRAM does Qwen 3.6 27B need?
About 18 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does Qwen 3.6 27B run on an RTX 4090 (24 GB)?
Yes. Qwen 3.6 27B needs about 18 GB at Q4_K_M, inside a 24 GB card, at an estimated 39 tokens/sec.
How do I run Qwen 3.6 27B locally?
Install Ollama and run `ollama run qwen3.6:27b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Qwen 3.6 come in?
Qwen 3.6 27B (18 GB), Qwen 3.6 35B-A3B (22 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
