The Beta (grok-imagine-video-1.5-beta) runs on a stable RunningHub workflow with flat per-clip pricing by duration (5 / 8 / 10 / 12 / 15s). 480p and 720p cost the same, the price is fixed before you generate, and 720p is noticeably cheaper than the Preview — ideal for budgeting, batch jobs and predictable cost. The Preview (grok-imagine-video-1.5) is billed per second plus a per-input-image fee, ships native synchronized audio, and ranks #1 on the Image-to-Video Arena (720p) — best when you want top quality and native audio. They are complementary channels, not the same endpoint.
The Beta fixes a single price for each duration tier (5 / 8 / 10 / 12 / 15s), independent of resolution, so you know the exact cost before hitting generate — handy for budgeting and batch cost control. The Preview bills per second plus per input image, which is more flexible but means the total varies with duration and the number of reference images.
