What does HeyGen Video 1 generate?
HeyGen describes a general-purpose scene model, distinct from its talking-avatar products. Its published workflow accepts text, an image or references and produces 5–15-second clips with native dialogue, ambience and effects, at up to 2K. The API model name is heygen-video-1. These are provider capabilities, not a PromptToVisual integration or our own output test.
Which leaderboard is it first on?
Checked October 23, 2026: Artificial Analysis lists HeyGen Video 1 first on AA-Video-T2V-Silent v2.1, at Elo 1144. Its with-audio AA-Video-T2V v2.1 table lists it third, at Elo 1160, with a rank range of 2–7. The two tracks answer different questions and their scores are not interchangeable. The rankings come from blind pairwise human preferences, not a guarantee about your brief or successful delivery. Treat a bare “No. 1 text-to-video” headline as incomplete without the category and date.
Where to try it or read the API contract
Use HeyGen’s official model page for its app entry, or its developer documentation for automation. Choose the exact text-to-video, image-to-video or reference mode before comparing settings and cost. Confirm the current resolution, duration, authentication and account quote there. This guide does not submit a job, create an API key or establish an unlimited free allowance.
Compare quotes at the same settings
HeyGen’s API marketing page currently advertises a time-limited October discount. Do not carry a promotional minimum into a long-term budget, or compare a low-resolution minimum with a different model’s longer, higher-resolution clip. Record duration, resolution, input references, sound, output count and the account’s actual charge together. A leaderboard’s normalized price is also a separate comparison condition, not your invoice.
A useful shot to evaluate
Our proposed brief: a locked camera facing one ceramic mug on a wooden table, warm window light, a faint curl of steam, quiet room ambience and no lettering. Start with one uncomplicated action. Inspect the mug handle frame by frame, listen for unexpected speech or music, and check whether objects change shape. For a reference-led job, compare the original product outline and markings against the result. This is an evaluation recipe, not a generated example.
When the existing Firestarter template is the better fit
If your task is a Firestarter-inspired dance from one adult photo, PromptToVisual already has a focused template using Seedance 2 Mini: 14 seconds, 720p, 9:16, silent MP4, at 70 paid credits. It uses your existing account and plans. It does not run HeyGen Video 1, generate native dialogue or guarantee exact choreography. Review the four real shared examples before choosing that workflow.
