Methodology
llamabench.ai community row, reporter @wmeddie: llama.cpp build b9935, flash-attention on, KV cache f16, 0.5k context depth, no speculative decoding. Decode = tg128 single-stream (per-request, batch-1); prefill = site-reported figure. n=1 per model row — crowd-sourced, not a curated scoreboard.
