Run it on a rented GPU

On a cloud GPU with enough memory, the same command you'd use locally works:

ollama run qwen3-coder-next

At Q4_K_M it needs about 49.1 GB, so pick a GPU with at least 56 GB.

Frequently asked questions

Can NVIDIA RTX 5080 run Qwen3 Coder Next 80B-A3B?

No. Even at Q4_K_M, Qwen3 Coder Next 80B-A3B needs about 49.1 GB, but the NVIDIA RTX 5080 has 16 GB usable. You could offload some layers to system RAM, but it will be very slow.

How much VRAM does Qwen3 Coder Next 80B-A3B need?

About 49.1 GB at Q4_K_M with 8,192 tokens of context, and about 160.2 GB at full FP16 precision.

How fast is Qwen3 Coder Next 80B-A3B on the NVIDIA RTX 5080?

It does not fit in the NVIDIA RTX 5080's memory, so most layers would run from system RAM and generation would be very slow.
