Fix everything except the model

The most common mistake in model comparison is changing two things at once. Same prompt, same duration, same aspect ratio, same seed where the model exposes one. If you let duration float between models, you are not comparing models — you are comparing shot lengths. Send one prompt to two or three models in a single run and the comparison is honest by construction.

Judge prompt adherence before aesthetics

Look at the output and ask one question first: does it show what I asked for? A beautiful clip with the wrong subject is a failure, and it is the failure mode people talk themselves out of because the clip looks good. Score adherence as a pass or fail, then rank the passes on aesthetics.

Test the thing you actually do

Do not benchmark on a generic 'cinematic drone shot over mountains' prompt if your work is talking-head B-roll and product reveals. Models are specialised in ways spec sheets do not capture. Build a three-prompt test set from your real work — one easy, one representative, one hard — and reuse it every time a new model lands.

Cost the decision in credits, not dollars

A model that costs twice as much but needs half the attempts is not more expensive. Track the number of generations it actually takes to get a usable clip, not the price of one. In our catalog that often means drafting on Seedance 2.0 Mini at 14 credits and rendering on Veo 3.1 at 85, which beats generating everything on the flagship.

Re-test when models update

Video models change fast, and a verdict from three months ago is not evidence today. Version bumps within a family are the ones worth re-running: Veo 3.1 versus Veo 3.1 Fast, Seedance 2.0 versus Seedance 2.5, Hailuo 2.3 versus Hailuo 2.3 Fast, Wan 3.0 versus Wan 3.0 Prime. Keep your test set so re-running takes five minutes rather than an afternoon.

How to Compare AI Video Models Properly FAQ

How many models should I compare at once?

Two or three. Beyond that you are reviewing clips rather than making a decision, and attention per clip drops fast.

Should I use the same seed across models?

Where the model exposes a seed, yes — it removes one source of variation. But do not over-index on it: different models interpret the same seed differently, so it is a weak control compared with fixing the prompt and duration.

How often do model rankings change?

Often enough that a quarterly re-test is worth it. Major family updates — Seedance 2.0 to 2.5, for example — can reorder a ranking in a single release.
