videoAbout Grok Imagine Video 1.5
Grok Imagine Video 1.5 is xAI's video model and the cheapest video model on NezhaGate. What sets it apart from everything else here is the billing shape: it is priced PER CLIP, so a 1-second and a 15-second render cost exactly the same; only the resolution changes the price (480P $0.30, 720P $0.40). Duration is any integer 1-15 seconds, resolution 480P / 720P, aspect ratio 16:9 / 9:16 / 1:1 / 4:3 / 3:4; omit the reference image for text-to-video, include up to 7 for image-to-video; every clip ships with a native audio track. Async job: POST /v1/videos/generations returns HTTP 202 and a job id immediately; poll GET /v1/videos/jobs/{id} until status=succeeded and read data[0].url. That link is an mp4 re-hosted by us -- it will not expire the way the upstream CDN link does.
Use cases
The lowest fixed cost per clip on the platform, so you can run dozens of prompts and keep the best one.
Per-clip pricing means the 15-second option is the best value; there is no reason to cut a clip short to save money.
9:16 straight out of the model for short-video platforms; 4:3 and 3:4 suit mixed image-and-text layouts.
Up to 7 reference images, useful for putting one character or product into different scenes.
How to choose
Pick it when budget comes first or when you are batching ideas -- it starts at $0.30, the cheapest video here, and per-clip pricing means 15 seconds costs no more than one. For a controllable soundtrack, reference audio or reference video use the Seedance family; for more than 15 seconds use seedance-2.5; for 1080P use minimax-h3.
