HappyHorse 1.1 is 12th at 1,042 Elo: what ranks above it on Sume

HappyHorse-1.1 is twelfth on Artificial Analysis's text-to-video board (AA-Video-T2V v2.0) with 1,042 Elo and a listed $10.80 per minute. Sume's video docs say Happy Horse 1.1 is not in the catalog. If you came for a HappyHorse-class clip through Sume, the six models that rank above it on the same board and are listed on Sume are Wan 3.0, Seedance 2.5, MiniMax H3, MiniMax H3 Max, Seedance 2.0 and Gemini Omni Flash 1.1.

HappyHorse across the three AA boards

The model has rows on all three boards that were read for this page. The 1.0 and 1.1 versions rank differently by task.

What sits above it on Sume

Every model below ranks higher than HappyHorse-1.1 on the text-to-video board and has a prompt-only Sume id. Sume's price is the list x 1.25 at the resolution shown.

The gap in numbers

H3 is 95 Elo points above HappyHorse-1.1 on the board (1,137 against 1,042) and costs less on both the board ($4.80 against $10.80) and on Sume ($4.50 per minute at 768p). That is not a close call on those two columns. It does not say whether the clip suits your brief, because a blind-vote score measures preference across many prompts.

What to check first

Check the HappyHorse features you rely on before you swap. If your job depends on a seed, a ratio such as 4:5, or lip-sync in a given language, confirm it in the Sume model's capabilities first. No Sume video model reports a seed, and the Gemini Omni id takes only 16:9 and 9:16. The page on models not on Sume maps each job to a listed id.

A swap test

If you currently use HappyHorse for a 5 second clip, the cheapest way to test a swap is one prompt through three Sume ids. MiniMax H3 at 768p costs 5 x $0.075 = $0.375, Gemini Omni Flash 1.1 at 720p costs 5 x $0.125 = $0.625 and Wan 3.0 at 720p costs $0.625. The three cost $1.625 in total.

Judge the clips against the same checklist you use today: subject stays on model, text is legible, motion is smooth. Keep the one that passes at the lowest price and note its length limit before you plan longer cuts.

This page makes no claim about HappyHorse's own features, limits or prices beyond the board figures, because the vendor pages were not readable on the day. If you rely on a feature such as a fixed seed, check it against the Sume model's capabilities: Sume's API reports seed: false for every model and returns 400 if you send one.
