Runway h3_max at 5 and 8 credits a second vs Sume's H3 Max
Runway lists h3_max at 5 credits per second for 480p and 8 for 768p. Sume's minimax-h3-max bills 480p, 768p and 1080p per second at list x 1.25. Side by side.
Runway's pricing page, read 2026-10-01, lists h3_max at 5 credits per second at 480p and 8 credits per second at 768p, with credits sold at $0.01. A 5-second clip is $0.25 at 480p and $0.40 at 768p. On Sume, minimax-h3-max reserves $0.32 and $0.50 for the same clip.
The Sume amounts are list x 1.25 rounded up to the cent, computed from Sume's pricing code. Runway's are its own price for its own product, so they are two quotes rather than a markup comparison.
What does each length cost?
Sume also prices a 1080p tier on this id. Per the video docs it is a latent refinement of native 768p, not a separate native resolution.
| Resolution | 5 s | 10 s | 15 s |
|---|---|---|---|
| 480p | $0.32 | $0.63 | $0.94 |
| 768p | $0.50 | $1.00 | $1.50 |
| 1080p | $1.00 | $2.00 | $3.00 |
What can the Sume row do?
minimax-h3-max takes text-to-video, first and last frames, and reference-to-video, for 5 to 15 seconds, with native stereo audio always on and no generate_audio toggle. Reference limits are up to 9 images, 3 videos and 3 audios, 12 in total, and audio cannot be the only reference. Aspect ratios include 21:9 and adaptive. Details are in the video docs.
How do I request 768p?
Use 768p, not 720p, on the MiniMax models.
