grok-imagine-video-1.5Grok Imagine Video 1.5 is xAI's video model with a trait most rivals still lack: it generates a synced audio track (dialogue, sound effects, ambience) together with the frames, so the MP4 you download is already H.264 video plus AAC audio — no separate dubbing step. One model name covers text-to-video and image-to-video (up to 7 reference images, URL or base64), any duration from 1 to 15 seconds, and three per-second tiers: 480p $0.0294/s, 720p $0.0529/s, 1080p $0.0882/s — 62-65% below xAI's official rates ($0.08 / $0.14 / $0.25 per second), and reference images are free here where the official API charges $0.01 each. A 4-second draft costs about $0.12; note that omitting resolution and duration defaults to 720p and 10 seconds (about $0.53), the shape both of our channels can serve. Output is watermark-free (we frame-checked both request types in production) and fast: a 4-second clip returns in roughly 30-70 seconds measured. Image-to-video is faithful to the reference — composition, subject and materials are preserved while the prompt drives motion and camera. Async create-then-poll on the unified video endpoint; failed tasks are never billed.

All six clips were generated on this exact model with native audio — four at the 480p / 8s tier ($0.24 each) and two at 1080p (4s $0.35, 10s $0.88). The prompt under each clip is exactly what produced it, and the tier tag shows what it cost. The four 480p prompts are adapted from our MiniMax H3 prompt library.

Sign up at APIMODELS, get your API key, and call our unified API endpoint. We provide detailed API documentation with code examples in cURL, Python, and Node.js.
APIMODELS offers the same Grok Imagine Video 1.5 model through our aggregation platform. We provide a unified API interface so you do not need separate accounts for each provider - one API key to access all models.
It's xAI's video generation model, and its stand-out trait is native audio: it produces a synced track of dialogue, sound effects and ambience together with the frames, so the MP4 you download is already H.264 video plus AAC audio. One model name covers text-to-video and image-to-video, any duration from 1 to 15 seconds, watermark-free. On apimodels.app it's priced per second, from $0.0294/s at 480p.
Per second by resolution: 480p $0.0294/s, 720p $0.0529/s, 1080p $0.0882/s. A 4-second 480p draft is about $0.12; a 15-second 1080p clip about $1.32. Text-to-video and image-to-video cost the same, reference images add nothing, and failed tasks are not billed.
POST to /api/v1/video/generations on apimodels.app with model "grok-imagine-video-1.5", a prompt and/or images (up to 7 references, URL or base64; at 1080p exactly one image, used as the start frame), then poll the same endpoint with the returned task_id. The request shape is identical to VEO, Kling and Seedance here — switching models is a one-string change and one API key covers everything. A 4-second clip returns in roughly 30-70 seconds measured.
Faithful, in our production tests: composition, subject and materials are preserved from the reference while the prompt drives motion and camera. References can be sent as raw base64 — we stage them to an accessible URL automatically. Keeping a product or character consistent while animating it is where this model shines.
Pick Grok Imagine Video when you want picture and sound in one pass — it ships a native synced audio track where most rivals output silent clips. Pick veo-3.1-fast-fhd for cheap fixed 8-second clips at a flat $0.07. Pick the Seedance 2 family for advanced controls like real-person assets and first/last frames. All three live on the same endpoint under the same API key, so comparing them is a one-string change.
On APIMODELS, Grok Imagine Video 1.5 runs alongside 60+ models on one API key and one balance, so choosing is about fit, not lock-in.
