Table

| gemini-omni-flash-1.1 | 360p | $0.0375 |
| wan-3.0 | 480p | $0.0625 |
| minimax-h3 | 480p | $0.0625 |

| seedance-2-fast | 480p | $0.1406 |

Using drafts well
A draft tier only helps if the winner can be re-rendered at the same prompt and seed-like settings at a larger size. Seedance keeps the same model across 480p, 720p and 1080p (except Fast and Mini, which stop at 720p), so a 480p draft followed by a 720p or 1080p final is a single-family workflow.
For a 6-second draft, one job costs $0.08 on Grok Imagine, $0.38 on Wan 3.0, $0.53 on Seedance 2.0 Mini and $1.62 on Seedance 2.5.
