Yes. d3 4B (vLLM Semantic Router, decision) fits in fast memory on RTX 3060 12GB at Q8_0 (6.9 GB needed, 11.5 GB usable), about 37 tok/s (estimate).
Hardware: RTX 3060 12GB · Model: d3 4B (vLLM Semantic Router, decision)
RTX 3060 12GB has 12 GB of VRAM and 360 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 4B (vLLM Semantic Router, decision) (4B, vLLM Semantic Router) at Q8_0 is a 5.8 GB download and needs 6.9 GB with headroom for about 8k tokens.
