Season 1 final results
Season 1 ran from 2026-08-13 to 2026-09-07: eight competitors, 90 benchmark outputs across 12 prompts, and 1,800 counted blind ballots. Voting is closed and these numbers are frozen — the table below will not change again.
First place
A 4-way technical draw: Claude Opus 5, GPT-5.6 Sol, Grok 4.6 and 3D-Agent
These four are separated by 108 rating points at the widest. The standard error on those gaps is around 98 points, so no pairing among them reaches significance at p < 0.05. The ballots genuinely cannot order them, and an arena that printed 1-2-3-4 anyway would be inventing a result its own data doesn't contain. They share the title.
Why that's a draw and not a ranking
Glicko-2 reports a rating deviation (RD) alongside every rating, and that RD is the standard error of the estimate. The gap between two competitors therefore has a standard error of √(RDa² + RDb²), and a two-sided z-test says whether the gap is real or noise. Here is that test for every pairing in the winning group:
| Pairing | Gap | Std. error | p-value | Verdict |
|---|---|---|---|---|
| Claude Opus 5 vs GPT-5.6 Sol | 14 | 99 | 0.888 | inseparable |
| Claude Opus 5 vs Grok 4.6 | 92 | 100 | 0.356 | inseparable |
| Claude Opus 5 vs 3D-Agent | 108 | 97 | 0.265 | inseparable |
| GPT-5.6 Sol vs Grok 4.6 | 78 | 100 | 0.434 | inseparable |
| GPT-5.6 Sol vs 3D-Agent | 94 | 97 | 0.332 | inseparable |
| Grok 4.6 vs 3D-Agent | 16 | 98 | 0.870 | inseparable |
The same test is what closes the group: the fifth-placed finisher is separated from the bottom of the winning group at p = 0.020, which is why the draw stops where it does rather than swallowing the whole table.
One caveat worth stating plainly. 3D-Agent reached the top group on 8 of 12 prompts, not the full set. Fewer prompts means a narrower sample of the benchmark, and its Season 1 coverage is the reason it re-ran the complete set for Season 2.

1= — Claude Opus 5, GPT-5.6 Sol, Grok 4.6, 3D-Agent (technical draw; ratings inside each other's margin of error)
2= — Claude Fable 5, Claude Opus 4.8, Claude Sonnet 5 (technical draw; ratings inside each other's margin of error)
Claude Haiku 4.5 finished unranked: it took 443 decisive votes but never pulled its rating deviation under the calibration floor, so Glicko-2 withholds a position. It is listed rather than hidden.
Who won each prompt
Head-to-head wins on each of the twelve prompts. A prompt winner here is simply whoever took the most blind votes on it — on most prompts the margins are small enough that this is a description, not a verdict.
| Prompt | Most wins | Record | Ballots |
|---|---|---|---|
| P01 Treasure chest | GPT-5.6 Sol | 37–10 | 160 |
| P02 Desk lamp | Claude Opus 5 | 32–2 | 164 |
| P03 Low-poly knight | Claude Opus 5 | 32–7 | 130 |
