Replicate Wan 2.1 at $0.09/s vs Sume Wan 3.0 480p: a 6-second clip

A 6-second Wan 2.1 clip at 480p on Replicate costs $0.54 (6 x $0.09 per output second), and a 6-second Wan 3.0 clip at 480p on Sume costs $0.375 (6 x $0.0625). These are different model versions, so this is a price comparison for someone choosing a Wan endpoint, not a claim that the outputs match.

The two price lists

Replicate's page lists Wan 2.1 (480p) at $0.09 per second of output video, under models billed by output rather than by hardware time. For private models it bills for setup, idle and active time instead. Sume bills the provider list price times 1.25 per output second.

Why the version matters

Wan 3.0 is the newer generation; Sume's catalog lists it at 480p, 720p and 1080p at $0.0625, $0.125 and $0.25 per second. Replicate's page row I read is 480p only; for 720p see Replicate Wan 2.1 720p vs Sume Wan 3.0 720p.

Choosing

If you need Wan 2.1 specifically, for a fine-tune or an existing pipeline, Sume does not list it and Replicate does. If you only need a cheap 480p text-to-video draft, the Sume row is 30 percent cheaper per second ($0.0625 against $0.09) before considering quality. Run both on the same prompts before moving a pipeline.

Checking your own settings

Replicate's example prices cover specific models, and the page notes that other models are billed by hardware time, so confirm the exact model page for the Wan variant you use before relying on $0.09. On Sume, GET /v1/videos/models returns the live per-SKU price and the supported durations for wan-3.0.

The cost of a failed or discarded clip counts too. If one clip in four is discarded, effective cost per kept 6-second clip is $0.54 / 0.75 = $0.72 on Replicate and $0.375 / 0.75 = $0.50 on Sume.

What I could not confirm

Replicate's pricing page lists Wan 2.1 at 480p only among the video rows I read, and it does not give a duration limit. No other Wan row or version is quoted. All vendor figures were read on 2026-10-09 and are listed in the sources; Sume figures come from its public catalog and docs the same day.
