Methodology

How we tested Grok Imagine 1.0 and PixVerse v5.5

We score two things separately: how good the video looks to a reviewer, and how reliably the file itself holds up. A model can make great-looking footage and still deliver clips with freezes, bad framing, or unstable motion.

We test every model with v-benchmark v2.0, our benchmark for AI video models — the same prompts, professional reviewers, and automated reliability checks behind every score here.

Reviewer scores
Both models receive the same prompts. Professional reviewers score how well each video follows the prompt and handles motion, composition, people, objects, animals, animation, and on-screen text. Scores use a 0-100 scale.
File reliability
Automated checks review 0 clips for freezes, bad framing, compression problems, unstable motion, distorted geometry, exposure problems, and invalid file properties.
Missing scores
Categories with a score for only one model are shown but excluded from the head-to-head win count. Price and generation speed stay separate because they use different units.
Last updated
Reviewer scores and rankings use results from July 22, 2026. Reliability results use the latest completed test for each model. Provider prices and rankings can change.
