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

Quoted against NVIDIA RTX 4090 (24 GB). Includes the KV cache at 8K context, so it reads higher than the headline figure.

Other Qwen 3.6 sizes

Qwen 3.6 35B-A3B~22 GB at Q4_K_M

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 40 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.
