Season 1 final results

Season 1 ran from 13 August 2026 to 7 September 2026: 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 four-way technical draw

Claude Opus 5, GPT-5.6 Sol, Grok 4.6 and 3D-Agent 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 can't order them, and printing them in order anyway would invent a result the 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:

The same test is what closes the group. A competitor joins a draw only if it is inseparable from every member, and the next finisher, Claude Fable 5, is separated from Claude Opus 5 at p < 0.001. That is why the draw stops where it does rather than swallowing the whole table.

3D-Agent reached the top group on 8 of 12 prompts, not the full set, which is why it re-ran the complete set for Season 2.
One caveat worth stating plainly

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 whoever took the most blind votes on it. On most prompts the margins are small enough that this is a description, not a verdict.

Check it yourself. Every ballot behind this table is published under CC BY 4.0, and the Season 1 outputs stay online at the paths voters saw them at. Re-run the Glicko-2 maths over the ballots and you should land on exactly these numbers. If you don't, tell us.

Season 2 is closed. Seven competitors, 1,687 counted ballots, and a five-way technical draw at the top.
