Runway real-time avatar cost per minute vs a rendered avatar video

Runway's page lists real-time avatars at 2 credits upfront and then 2 credits per 6 seconds, and credits cost $0.01 each, so a one-minute live session is 22 credits or $0.22. Sume does not offer a live, interactive avatar: it renders a finished avatar video at $0.184, $0.245 or $0.55 per second depending on quality, which is a different product at a very different price.

If you searched for the cost of a real-time AI avatar, this post gives the Runway arithmetic. If you wanted a talking-head file for an ad or a lesson, the Sume numbers are further down.

How is a Runway real-time avatar session billed?

The Runway pricing page, read on 2026-10-02, says credits are purchased at $0.01 per credit and lists real-time avatars as "2 credits upfront, then 2 credits per 6 seconds". That is a connection fee of $0.02 plus $0.02 for every 6 seconds of session.

The cost grows in 6-second steps of session time. The page does not say how an idle or silent session is billed, so confirm that with Runway and cap session length in your app.

How does Sume bill an avatar video?

Sume's Avatar 1.0 talking video is rendered, not live. You send a ready avatar handle and a script; Sume accepts scripts whose estimated duration is 4 to 60 seconds and returns a video file. It is priced per second by quality tier, with a higher rate when a product image is included.

Creating the reusable avatar itself is a one-time $0.95. The tiers are described in Generate avatar video: standard is the fastest path, plus is the default, and max is the highest quality and slower.

Why is the rendered video so much dearer per minute?

Because the two bill different things. Runway's price covers a conversational session. Sume's price covers a rendered shot of a presenter with generated video frames, at 720p today. A minute of Sume Standard is $11.04, about 50 times the $0.22 Runway session minute, and neither number says anything about quality.

The honest comparison is the use case. A support kiosk needs a live reply and gets nothing from a rendered file. A product demo you will post a thousand times needs a file, and rendering it once at $1.84 for ten seconds beats paying for a live session every time someone watches.

What should I price for each use?

For a live agent, estimate average session minutes times concurrent sessions and add the per-session connection credits. For a video library, count seconds of finished video and multiply by the tier rate. Sume also reserves the estimated amount when a job is accepted and releases it if the job fails, so a failed render does not leave a charge.

If you are unsure which you need, read Avatar models for what Sume accepts, then compare against the live-versus-rendered tradeoffs in our real-time versus rendered avatar post.

How do I decide between live and rendered?

Ask who watches and when. If one person talks to the avatar and the answer must come back in seconds, you need a live product and the Runway session arithmetic is the budget. If many people watch the same video, render it once.

A middle path is to render the common answers as short clips and use a live session only for the long tail. At $1.84 for a 10-second Standard clip on Sume, a library of 50 short answers is $92, and it is paid once.

Whichever you pick, put a time limit on live sessions and a spend limit on batch renders. Both meters run whether or not anyone is happy with the result.
