No. Even at Q4_K_M, gpt-oss 120B needs about 72 GB, but the NVIDIA RTX 3060 12GB has 12 GB usable. You could offload some layers to system RAM, but it will be very slow.

Try other context lengths

Run it on a rented GPU

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

ollama run gpt-oss:120b

At Q4_K_M it needs about 72 GB, so pick a GPU with at least 80 GB.

Frequently asked questions

Can NVIDIA RTX 3060 12GB run gpt-oss 120B?

No. Even at Q4_K_M, gpt-oss 120B needs about 72 GB, but the NVIDIA RTX 3060 12GB has 12 GB usable. You could offload some layers to system RAM, but it will be very slow.

How much VRAM does gpt-oss 120B need?

About 72 GB at Q4_K_M with 8,192 tokens of context, and about 234.8 GB at full FP16 precision.

How fast is gpt-oss 120B on the NVIDIA RTX 3060 12GB?

It does not fit in the NVIDIA RTX 3060 12GB's memory, so most layers would run from system RAM and generation would be very slow.
