Grok Imagine 1.5. xAI video, now up to 1080p.
The step up from Grok Imagine. The same 1 to 15 second range and seven aspect ratios, with output that reaches 1080p where the original stops at 720p. Start from a prompt, an exact first frame, or reference images.
- 1 to 15 second clips
- 7 aspect ratios
- First frame control
- Reference images
- Up to 1080p
Grok Imagine 1.5 keeps the working range of the original and raises the resolution ceiling. Clips still run from a 1 second sting to a 15 second beat at any whole second, the seven aspect ratios still include 3:2 and 2:3 alongside landscape, portrait, and square, and output goes up to 1080p. Give it a text prompt, an exact starting image, or a set of reference images, and the clip comes back with sound generated for the scene.
On Treza, 1.5 sits beside Grok Imagine 1.0 in the Video Generation node's picker and in chat, and the two work as a pair. 1.5 costs more per second at every resolution they share, so the natural pattern is to sketch on Grok Imagine and re-render the keeper on 1.5 at 1080p. The node's Resolution setting picks 480p, 720p, or 1080p per clip. Like every model here, it bills from prepaid credits, and only successful runs are charged.
Up to 1080p
Pick 480p, 720p, or 1080p on the node. 1080p is a step past the original's 720p ceiling, for clips that will play large on a landing page or in a full-screen cut.
1 to 15 seconds
Any whole second from a 1 second logo sting to a 15 second beat, so transitions and full social moments come from the same model.
Frames and references
Open on an exact first frame, or wire several reference images into the node to carry a subject or a style into the clip.
Sound with the picture
Clips come back with audio generated for the scene, so ambience and effects arrive with the shot rather than in a separate pass.
What to make with Grok Imagine 1.5
Real prompts, and what comes back. Every one runs in Treza chat or as a node on the canvas.
“A 2 second logo sting: sparks gather and the logo snaps into place”
A short intro sting for videos and streams.
“Start on this product photo (attached): the lid lifts and warm light spills out”
Image-to-video from your exact opening frame.
“Same prompt as the Grok Imagine draft, re-rendered on 1.5 at 1080p for the site hero”
The keeper, rendered for a large placement.
“A 15 second timelapse of a harbor from dusk to night, waves on the pier, 16:9”
A long mood beat with the sound of the water.
“A 3:2 shot of a record spinning on a turntable, warm lamp light”
A frame sized for less common placements.
“A skateboarder drops into a bowl at golden hour, 9:16”
A vertical beat for Shorts and Reels.
Grok Imagine 1.5 is one node on a canvas
Chain it with language, image, and video models, then publish the whole pipeline as an API. See how a full AI video pipeline fits together.
- Step 01
Draft the brief
A language model node expands a one-line idea into a detailed, on-brand prompt before it ever reaches the model.
- Step 02
Generate with Grok Imagine 1.5
Run variants in parallel, compare against other models on the same prompt, and keep every result in run history.
- Step 03
Publish it as an API
The pipeline becomes a versioned endpoint. Your product calls it with the typed /invoke API or any OpenAI SDK.
Grok Imagine 1.5 as an API, priced per clip
The Grok Imagine 1.5 API
Build a pipeline with Grok Imagine 1.5 on a node and publish it. It becomes a versioned HTTP endpoint: the typed /invoke route enqueues a run and returns a run id to poll, and an OpenAI-compatible route works with SDKs you already use. Agents connect over MCP the same way. Your prompt engineering ships inside the pipeline, so every caller gets your quality, and swapping the model later does not change the API your product calls.
Grok Imagine 1.5 pricing
Prepaid credits, no subscription. Each clip is charged at Grok Imagine 1.5's own rate from your balance, shown before you run, and only successful generations are charged, so a failed run costs nothing. Credit packs start at $5 and never expire, which suits spiky production schedules. Run history records the cost of every generation, per node, so spend is auditable rather than a surprise.
Grok Imagine 1.5, answered
What is the difference between Grok Imagine 1.5 and Grok Imagine?
Resolution and price. Both run 1 to 15 seconds in the same seven aspect ratios, start from a first frame, and take reference images. 1.5 reaches 1080p where the original stops at 720p, and costs more per second at the resolutions they share. The original suits high-volume drafts, and 1.5 is where the chosen idea gets its final render.
How do I get 1080p from Grok Imagine 1.5?
Set Resolution to 1080p on the Video Generation node, or ask for 1080p in chat. The same setting offers 480p and 720p for cheaper drafts, and the price per second follows the resolution you pick.
Does Grok Imagine 1.5 generate audio?
Yes. Clips come back with sound generated for the scene. For narration over the picture, add a Text to Speech node and mix the two in the Sequence node, which can duck the clip's own audio under the voice.
How much does Grok Imagine 1.5 cost on Treza?
Treza uses prepaid credits with no subscription. Each clip is charged at Grok Imagine 1.5's rate from your balance, and only successful generations are charged. Credit packs start at $5 and never expire.
Can I call Grok Imagine 1.5 through an API?
Yes. Build a pipeline that uses Grok Imagine 1.5 and publish it as a versioned HTTP endpoint. Call the typed /invoke API from your product, or point any OpenAI SDK at the OpenAI-compatible endpoint. If a better model ships later, swap it on the node without changing the API your product calls.
