Can a RTX 3080 12GB run d3 27B (vLLM Semantic Router, decision)?

No. d3 27B (vLLM Semantic Router, decision) does not fit on RTX 3080 12GB: Q8_0 needs 32.3 GB and 11.5 GB is usable.

Hardware: RTX 3080 12GB · Model: d3 27B (vLLM Semantic Router, decision)

RTX 3080 12GB has 12 GB of VRAM and 912 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 11.5 GB. Partial offload may also use 60% of that system RAM. d3 27B (vLLM Semantic Router, decision) (27B, vLLM Semantic Router) at Q8_0 is a 30 GB download and needs 32.3 GB with headroom for about 8k tokens.
