Per-concurrency aggregates (cross-model)
| Model | Source | N=1 wall | N=5 wall | N=5 throughput | N=5 speedup | N=5 efficiency |
|---|---|---|---|---|---|---|

Per-task quality (Phase 1 — judge scored 1-5)
Mean judge score by task × N (LLM-judge, correctness + completeness + concision, averaged across 3 reps):
| Task | N=1 | N=2 | N=3 | N=4 | N=5 |
|---|---|---|---|---|---|
| code_review | 4.22 | 2.94 | 3.11 | 3.08 | 2.93 |
| doc_generation | 3.56 | 3.33 | 3.04 | 3.39 | 3.04 |
| test_generation | 2.22 | 1.89 | 2.22 | 2.25 | 1.98 |
| refactor | 2.44 | 2.78 | 2.85 | 2.67 | 2.69 |
| design_doc | 1.78 | 2.22 | 2.15 | 2.50 | 2.24 |
Quality observations:
- code_review peaks at N=1 (4.22) and degrades ~30% by N=5 — the only task with clear N-related degradation
- design_doc is the worst-scored task across all N — judge may be too strict for 2K-word synthesis, or this is just hard for minimax-m3
- test_generation is consistently low (~2.0) regardless of N — flat-line quality
- refactor and doc_generation are flat across N
Variance estimates (3 reps per cell)
Standard deviation across reps, per (model, N) cell, for wall_clock_s:
| σ(N=1) | σ(N=2) | σ(N=3) | σ(N=4) | σ(N=5) | |
|---|---|---|---|---|---|
| direct-minimax | 12.5 | 13.6 | 4.6 | 6.8 | 14.5 |
| minimax-m3 (skynet) | 7.2 | 5.4 | 7.3 | 1.5 | 9.4 |
| codex-gpt-5.4 | 4.9 | 8.4 | 3.8 | 27.5 | 2.2 |
| xai/grok-3-mini | 5.8 | 3.0 | 2.9 | 4.1 | 7.7 |
| zai-coding/glm-5.2 | 7.6 | 7.0 | 7.4 | 9.8 | 12.4 |
Most cells σ < 15s — improvements smaller than that are within noise. High-σ cells (codex N=4 = 27.5s, direct-minimax N=5 = 14.5s) reflect genuine single-trial outliers.
Cross-model comparison (mistral-large excluded)
| Model | Best N | Peak speedup | Cost (5 trials N=5) | Notes |
|---|---|---|---|---|
| xai/grok-3-mini | N=4 | 5.01× | $0 | Beat ideal-linear at N=4 (125% efficiency) |
| MiniMax-M3 (direct) | N=4 | 3.49× | $0 | Slow N=1, scales well |
| codex-gpt-5.4 | N=5 | 3.66× | $0 | Middle of pack |
| zai-coding/glm-5.2 | N=4 | 3.26× | $0 | Slow due to reasoning-token budget |
| minimax-m3 (Skynet) | N=5 | 3.17× | $0 | Fastest N=1 at 29.3s |
Hypothesis scorecard
