What 10 seconds of talking avatar video costs on Sume

A 10-second talking avatar video costs $1.84 on Sume's standard tier, $2.45 on plus (the default) and $5.50 on max, with no product image. Add a product_image and it is $1.94, $2.58 and $5.80. Sume bills avatar video per second at a fixed rate per tier, so the cost of any length is the rate times the estimated seconds, between the 4-second minimum and the 60-second maximum.

The rates come from the catalog rate card shipped with the Sume API (sume_avatar_video_fixed_tier_rates_2026_07_02); confirm them live with GET /v1/catalog before you build a budget on them.

Sume rates for a 10-second clip

The per-second rates multiply cleanly.

The Hedra table is a different product

Hedra published a price comparison on 2026-09-25 for one fixed job: a 10-second, 1080p clip with native audio generated from a start frame, using rates from its own API catalog. Its table runs from $0.60 for LTX-2.3 Fast to $7.91 for Seedance 2.5, with Kling V3 Pro at $1.68 and Wan 3.0 Standard at $2.00.

Read that table as a price list for general video models, not for talking avatars. A start-frame video model animates a scene and can generate sound; it does not take your script and keep one presenter's face and voice consistent. A rendered avatar clip from Sume is script in, presenter out, at 720p. Putting $2.45 next to $1.68 and calling it a like-for-like comparison would be wrong, because the 1080p general clip and the 720p presenter clip are different deliverables.

The overlap is real only in one place: if your 10 seconds is B-roll or product motion with no talking face, a general video model is the right line item, and Sume's models page lists those separately from avatar video.

Working out your own number

Per-second billing also means a rewrite that trims two seconds saves two seconds of cost, which is rarely true of plans that sell a fixed bundle of minutes.

• Count the words and speak them at a normal pace; Sume estimates duration from the script and rejects estimates outside 4 to 60 seconds.
• Pick the tier. standard is the fastest path, plus is balanced, max is highest quality and slower.
• Add the product-image rate only if you pass product_image.
• Preview first when the framing is uncertain: preview stills are tier-independent, and generate-video can set the final tier.

Limits

Avatar video is 720p today, up to 60 seconds per job, and one avatar per video. Hedra's rates are as published on the date above and may change.
