Tavus overage $0.37 a minute vs Sume avatar $0.184 a second: 30x gap

Tavus lists Starter overage at $0.37 per minute, which is $0.37 / 60 = $0.00617 per second. Sume's avatar video standard tier is $0.184 per second, or $11.04 per minute. The ratio is 11.04 / 0.37 = 29.8, so a minute of Sume standard avatar video costs about 30 times a minute of Tavus Starter overage (Tavus pricing and Sume catalog, read 2026-10-09). The numbers are real, but the two things are not the same product, and the ratio should not be read as a price war.

Tavus sells minutes of live conversational video. Sume sells a finished, script-driven video clip. One is a session, the other an artifact.

The numbers side by side

Tavus's pricing page lists Starter at $59 a month with 100 minutes included and $0.37 per minute overage, and Growth at $397 a month with 1,250 minutes and $0.32 per minute overage. Growth works out to $397 / 1,250 = $0.3176 per included minute.

Why the gap exists

A live session streams a conversation that the viewer steers. A job renders a specified video: the script, the avatar, the scene, optional product image and captions, delivered as a file on a hosted URL. Per second of output, the rendered clip carries a different workload. The Tavus page also does not tell you what the minutes cover beyond conversational video, so do not assume a minute of one equals a minute of the other.

If your goal is a 45-second welcome that 3,000 customers will each see once, the unit that matters is the clip, not the minute: one $8.28 standard job (45 x 0.184) serves all 3,000. If your goal is 3,000 separate live conversations, you need a live product and Sume's docs do not describe one.

How to compare honestly

Put your own usage in the unit each vendor bills. For live minutes, count the minutes people will actually talk. For recorded clips, count output seconds, then multiply by the tier you will use. A 12-minute weekly live office hour is 12 minutes of Tavus-style usage. Twelve 30-second personalized clips a week is 360 seconds, or $66.24 at standard on Sume. Neither number says which tool is cheaper, because they answer different needs.

What to measure first

Before you compare any two vendors, write down the unit of work you actually need. If a customer talks to the avatar, count conversation minutes and peak simultaneous sessions. If you publish a finished clip, count output seconds and the number of variants. A single 45-second clip and 3,000 live minutes are different budgets, and mixing them is how a $0.37 figure ends up beside a $0.184 figure in a slide that means nothing.

Then check what each price includes. The Tavus page lists minutes and concurrency by plan. The Sume catalog lists a price per output second, plus $0.95 to create an avatar. Neither page promises quality or fit for your case, so test a small sample on each before you scale.
