HeyGen launches Avatar 4 with one-photo lifelike avatars, intensifying avatar realism competition

HeyGen released Avatar 4, enabling one-photo-to-lifelike avatar generation with expressive motion, lip sync, full body, multiple styles, and 1080p output. This directly competes with Creatify's Aurora avatar model, which already lagged behind HeyGen in realism. The update raises the bar for avatar quality and could further erode Creatify's differentiation in AI video ads.
