aiden production-1.2 — 2x hardmode (first ever measurement, 2026-09-06 night)

Image: aidendle94/sparkrun-vllm-glm53-gb10:production-1.2 (vLLM 0.1.dev20051+g487ecf187, torch 2.12.0 / flashinfer 0.6.15 lineage) Weights: LibertAIDAI/GLM-5.3-Flash-NVFP4 (97 GiB/node), KV 461,730 tokens (fp8_e4m3, 4 GiB pin), --enforce-eager, DFlash2 k=7 (incoai drafter), SM90-NoPE FA2 route, TP=2 on 2nodes-dac (dgx1+dgx2). Bench: tool-eval-bench 2.6.1.dev46, seed 42, hardmode, --perf, c1/c2.

Score: 159/176 (90.4) — 74 pass / 11 partial / 3 fail

New 2x quality record of the campaign (+1 vs r18-2x-nvfp4kv-spark 158), but the perf profile is weaker and the KV pool 5x smaller:

lane (2x, seed 42) score pp c1 d0 tg c2 d0 TTFT d0 c1 KV tokens
r18-2x-nvfp4kv-spark 158 1,861 36.0 1,236ms 2,136,194
aiden 1.2 (this run) 159 1,271 30.1 1,802ms 461,730
r27 (same 2x config) 156 1,356 31.4 1,535ms 2,206,618

Perf (llama-benchy pp2048 tg128): c1 1,271/23.5 → 1,669/22.8 (d0→d8192); c2 1,428/30.1 → 1,643/22.2. DFlash2 spec healthy: mean acceptance length 4.27–4.94 (k=7; recipe warns <0.15 = broken aux capture).

Fails (3): TC-43 Omitted Required Parameter, TC-58 Fake System Message in File, TC-61 Async Polling. Partials (11): TC-11/35/39/46/53/57/63/69/75/82/85.

Interpretation

  • Aiden's lane is a quality winner at 2x by one point — within run-to-run noise of the r18-spark lane, NOT a clear win.
  • It trades latency (eager, no graphs), prefill and 5x less KV headroom for that point. For interactive agent serving the r18-spark profile (2.1M KV, 36 t/s, 1.2s TTFT) remains the better 2x shape; aiden is the reference lane for "community stack" parity (and the DFlash2 drafter WORKS here — the r18-fork C4-page assert is fork-specific, not drafter-specific).
  • Note: benched with tool-eval-bench dev46 (campaign anchors ran dev45) — ±1 point version drift vs the r17abi 153 gate.
