signal path of one layer, generated from the registry's structured fields — dimension lines quote the model's real numbers; an MoE trace forks at the router, a dense trace runs straight through. Geometry fields come from the repo's config.json.
# why ranked
Overall: #30 — score 68.3 ● high — all signals present
| signal | weight | input (0–100) |
|---|---|---|
| aa_intelligence | 0.70 | 69.9 |
| bench_composite | 0.30 | 64.5 |
benchmark panel evidence:
| complete panel | score (0–100) |
|---|---|
| aa-math-v1 | 76.0 |
| swe-bench-verified-v1 | 52.9 |
Coding: provisional — score 52.6 ● low — a single signal; treat with caution
provisional: too few independent signals for a numbered position — the score is shown, but this model sorts after every ranked model.
| signal | weight | input (0–100) |
|---|---|---|
| aa_coding | 0.30 | — |
| aider_polyglot | 0.30 | — |
| swe_bench_verified | 0.40 | 52.6 |
missing signals are dropped and the remaining weights renormalized — never imputed.
Agentic: #11 — score 52.6 ● low — a single signal; treat with caution
| signal | weight | input (0–100) |

| swe_bench_verified | 0.60 | 52.6 |
| swe_rebench | 0.40 | — |
missing signals are dropped and the remaining weights renormalized — never imputed.
