- Single-stream decode, batch 1, one concurrent request. n=9 generations (3 prompt kinds x 3 repeats), 512 output tokens each, streaming, temperature 0.60 top_p 0.95 top_k 20. Served context length 131072 (this is the CONFIGURED window, not the prompt depth; prompts here are short). mem-fraction-static 0.80, kv-cache-dtype fp8_e4m3, attention backend flashinfer, tp 1, max-running-requests 32. Idle box, one model loaded at a time, all six cells of the battery ran back to back in one session on one machine. Speculative decoding OFF (no draft model loaded). Per-workload decode: code 12.38, reasoning 12.37, prose 12.38 tok/s; the headline figure is the mean of all 9. Quantization detail: RadixArk NVFP4 build of the same base model. Served from a local copy; the hub revision was not recorded, so this run pins the checkpoint by its config.json sha256 instead (see config-hashes.txt in the artifact directory). Measured with a 3-prompt-kind by 3-repeat battery; per-run rows, the resolved server args and the launch script are retained locally as speed-rarkfp4-off.json, serverinfo-rarkfp4-off.json and battery.log. Happy to share the raw rows on request.
