- Benchmarked via LM Studio REST /api/v0/chat/completions. Median of 2 measured 512-token generations after 1 warm-up; temperature 0; fixed prompt (43 prompt tokens). Runtime: llama.cpp-linux-arm64-nvidia-cuda13 v2.20.1, CUDA 13.0, driver 580.142. NVIDIA DGX Spark (GB10 Grace Blackwell), 20-core Grace ARM (Cortex-X925/A725), 121 GiB unified memory. Note: gemma-4 is a reasoning model; ~509 of 512 output tokens were reasoning tokens.
