Grok Imagine 1.5 Lite is xAI's distilled version of Grok Imagine 1.5, listed on OpenRouter on 2026-10-06. It keeps the working range of the full model: any whole second from 1 to 15, seven aspect ratios including 3:2 and 2:3, and output at 480p, 720p or 1080p. It trades some quality for speed and price. OpenRouter lists it at $0.02 a second at 480p, $0.03 at 720p and $0.14 at 1080p, plus a cent for an input image, against $0.08, $0.14 and $0.25 for Grok Imagine 1.5.
On Treza it sits beside Grok Imagine 1.5 in the Video Generation node's picker and in chat. In our tests a 4 second 480p clip billed exactly $0.08 and came back in 36 seconds at 24 frames a second, and with no Resolution set the node renders 480p. It takes a first frame but refuses reference images, so wire references into Grok Imagine 1.5 instead. It bills from prepaid credits, and a failed generation costs nothing.
Two cents a second at 480p
The listed rate at 480p is a quarter of Grok Imagine 1.5's, and 720p costs $0.03 a second. In our tests a 4 second 480p clip billed $0.08, exactly the list price.
1 to 15 seconds
Any whole second from a 1 second sting to a 15 second beat, in 16:9, 9:16, 1:1, 4:3, 3:4, 3:2 or 2:3.

First frame control
Open on an exact image for a cent more. In our test the clip started on the photo and moved into the scene the prompt described, at the photo's own aspect ratio.
What to make with Grok Imagine 1.5 Lite
Real prompts, and what comes back. Every one runs in Treza chat or as a node on the canvas.
“A barista pours steamed milk into a latte in a sunlit cafe, slow push-in, 9:16”
A vertical cafe beat with shallow focus, our benchmark clip.
“A 2 second logo sting: sparks gather and the logo snaps into place”
A short intro for videos and streams, for a few cents.
“Start on this product photo (attached): the lid lifts and warm light spills out”
Image-to-video from your exact opening frame.
“Ten variations of a drone shot over a coastline at golden hour, 16:9”
A cheap batch to pick a direction from before the final render.
“A 3:2 shot of a record spinning on a turntable, warm lamp light”
A frame sized for less common placements.
“A 15 second timelapse of a harbor from dusk to night, 1080p”
A long mood beat at the top resolution setting.
Grok Imagine 1.5 Lite 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 Lite
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 Lite as an API, priced per clip
The Grok Imagine 1.5 Lite API
Build a pipeline with Grok Imagine 1.5 Lite 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 Lite pricing
Prepaid credits, no subscription. Each clip is charged at Grok Imagine 1.5 Lite's own rate from your balance, shown before you run, and a failed generation 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 Lite, answered
What is the difference between Grok Imagine 1.5 Lite and Grok Imagine 1.5?
Price, speed and references. Lite is distilled from 1.5 and lists at a quarter of its price per second at 480p and 720p, and about half at 1080p. Both run 1 to 15 seconds in the same seven aspect ratios and start from a first frame. Only 1.5 takes reference images; Lite refuses them.
What does Grok Imagine 1.5 Lite cost per second?
OpenRouter lists $0.02 a second at 480p, $0.03 at 720p and $0.14 at 1080p, plus $0.01 for an input image. In our tests a 4 second 480p clip billed $0.08 and the same clip with a first frame $0.09, exactly those rates. Treza quotes the listed price plus its credit markup before a run.
Does Grok Imagine 1.5 Lite generate audio?
Clips come back with an audio track, but in our tests it was close to silent. Plan on adding sound in the pipeline: a Text to Speech node for narration or a music node for a bed, mixed in the Sequence node.
How much does Grok Imagine 1.5 Lite cost on Treza?
Treza uses prepaid credits with no subscription. Each clip is charged at Grok Imagine 1.5 Lite'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 Lite through an API?
Yes. Build a pipeline that uses Grok Imagine 1.5 Lite 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.
