HeyGen Video adds 2K output through its API
HeyGen says its own HeyGen Video API now renders 2K clips from text or image references. The default remains 768p, while 2K costs three times the 768p rate for generated seconds and reference-video seconds. The changelog gives October 2026 but no exact day. HeyGen describes the model as built on MiniMax H3 and post-trained by HeyGen, rather than a new model trained from scratch by HeyGen.
