Can you buy Tavus Griffin-Lite? Presenter video options today
Tavus Griffin-Lite is a research preview for trusted testers, not a product customers can buy. What Sume ships for presenter videos in the meantime.
Sume Avatar 1.0
Sume Avatar 1.0 by API: reusable avatars, talking video from a script, multi-scene and two-speaker videos, previews, B-roll, and Face Swap (Beta).
Start with: Introducing Sume Avatar 1.0
Vidu Q4 audio references vs a scripted avatar: which keeps a voice?

Face-swap clip on YouTube: label needed? Sume's beta caps at 15 s
YouTube asks for a label when a real person appears to say or do something they did not. Sume's face swap beta takes about 4 to 15 seconds; $3.68 max at plus.
Griffin-Lite 48% is 26 of 54 callers: how wide is the range?
Tavus reports 48% of 54 callers took Griffin-Lite for human. A 95% Wilson interval on 26 of 54 is about 35% to 61%. What that means for buyers.
HeyGen Creator is $29: how many seconds is $29 on Sume Avatar?
At Sume's $0.184 standard rate, $29 buys 157 seconds of Avatar 1.0 video, 118 at plus and 52 at max. A fair way to compare it with HeyGen Creator.
HeyGen twins take 10-20 min: how do Sume avatar jobs show progress?

HeyGen Free allows 3 videos of 1 minute: the same on Sume costs $33.12
HeyGen's Free plan lists 3 videos a month at 1 minute. Three 60-second Sume Avatar 1.0 clips cost $33.12 at standard, $44.10 at plus, $99.00 at max.
Korean avatar captions: slam style returns 400, use a Hangul style
Sume rejects a Korean script with slam, punch or tiktok-green captions (400 caption_hangul_text_latin_style). Pick a Hangul style such as korean-ad.
Live AI avatar vs recorded clip: who reviews the words first?
A live avatar speaks in real time; a Sume Avatar 1.0 clip is scripted, previewable and fixed. Why that matters while Tavus says disclosure features are coming.
Synthesia Pro yearly, $64/mo: break-even vs Sume is 69.6 minutes

Will a YouTube AI label hurt reach? What the page says

A $10 avatar video pilot: 49 seconds on Sume vs free plan limits
With $10 you can create one Sume avatar ($0.95) and render 49 seconds at standard, 36 at plus or 16 at max. Compare with HeyGen Free and Synthesia Basic limits.
