HeyGen Puts Rival AI Avatar Tools Side by Side, Spotlighting the Identity-Drift Gap Its New Avatar V Model Claims to Close

HeyGen published a side-by-side video test pitting two AI-generated avatars of the same person against each other, built on the same script and audio track but produced with two different avatar tools — and the comparison doubles as a case study for the identity-consistency problem the company says its newest model, Avatar V, was built to solve. In the clip, one avatar tracks convincingly as the real person throughout; the other is close enough to register as the same face at a glance but drifts just enough — in expression, geometry, or motion — to read as subtly wrong, the kind of discrepancy viewers notice without being able to immediately name.
