Is MiniMax H3 Max 1080p native? Sume's catalog and price

No. On Sume, minimax-h3-max is native at 480p and 768p, and its 1080p is a latent refinement from the 768p render. The price follows the rung: $0.0625 a second at 480p, $0.10 at 768p and $0.20 at 1080p, so a 10-second clip is $0.63, $1.00 or $2.00.

That wording comes from Sume's own catalog notes on the Video Router page, read 2026-10-06, which also gives the provider list rates ($0.05, $0.08 and $0.16 a second) that Sume multiplies by 1.25.

What does each rung cost?

Ten seconds on minimax-h3-max at each resolution it lists.

Should I pay for 1080p?

That depends on the screen. If the clip will be seen on a phone, the 768p render at half the 1080p price is the sensible default. Pay for 1080p when the destination demands a 1080-pixel file. For a true 1080p model with a different price shape, compare wan-3.0 at $2.50 for 10 seconds.

What about audio?

H3 Max has native stereo audio, and it reports image, video and audio input references, so a track can steer the clip.
