Actual usage is 1.46 GiB for consumed memory (weights + non-torch), 0.54 GiB for peak activation, and 0.18 GiB for CUDAGraph memory. Replace gpu_memory_utilization config with `--kv-cache-memory=9330934272` (8.69 GiB) to fit into requested memory, or `--kv-cache-memory=20957086208` (19.52 GiB) to fully utilize gpu memory. Current kv cache memory in use is 9.02 GiB.
