memory samples

tok/s and latency measure the scored generation window; per-test figures above are the readings for each case. Memory (VRAM, unified RAM, or host RAM) is the peak footprint polled throughout the run, or blank when no probe could attribute it — never a hand-typed number.

Reproduce this run

The private prompts never leave the suite. What’s public is the command, the pinned suite, and the hashes that stand in for the tests — enough to re-run the exact config against your own copy of the suite.
