sync-3 at $0.133 a second vs Sume quality tiers
Sync lists sync-3 lipsync at $0.133 a second and native 4K. Sume avatar video has standard, plus and max tiers, and face swap is a Beta for short sources.
Sync prices its sync-3 lipsync model at $0.133 a second, so a 10 second clip is $1.33 at the listed rate. Sume has no lipsync-only product in the docs read here; it offers script-driven avatar video in three quality tiers and a Beta face swap. They solve different problems, so compare the job, not just the rate.
What Sync lists
The Sync documentation describes sync-3 as native 4K, priced from $0.02 a second (lipsync-1.9) to $0.133 a second (sync-3) at 25 fps. lipsync-2 and lipsync-2-pro are 512x512, and maximum video length is up to 30 minutes depending on the plan. The listed models are lipsync-1.9, lipsync-2, lipsync-2-pro, react-1 and sync-3.

| Longest video | Up to 30 minutes, by plan |
Sume avatar video tiers
POST /v1/avatar-1.0/talking-video makes a talking video from a ready avatar and a script of 4 to 60 seconds. quality is standard (fastest), plus (the default when omitted) or max (highest, slower). Resolution is currently 720p. The docs read here give no per-second prices for these tiers, so use the catalog or a preflight for costs.
Sume face swap
Avatar Face Swap 1.0 is a Beta endpoint at POST /v1/models/sume/avatar-face-swap/v1.0/runs. It takes an avatar_handle, a public HTTPS video_url, and a required quality of standard, plus or max. Source videos are planned for about 4 to 15 seconds with usable audio. It applies an avatar face to a video; it is not a general lipsync tool for arbitrary footage.
Choosing
If you have footage and need new speech synced to it at up to 4K, Sync's page describes that. If you need a presenter video from a script, Sume Avatar fits. Check the output on a test clip before you commit to either, and read how each handles resolution, because the two pages above state different resolutions.
