On 8 October 2026, the official Grok Imagine account said Video 1.5 Lite is live in the Grok Imagine API.

Video 1.5 Lite is live in the Grok Imagine API. The new workhorse for text-to-video and image-to-video.

$0.02/sec at 480p $0.03/sec at 720p $0.14/sec at 1080p

Elon Musk replied to that post: “Automatically used by Grok @Bot.”

What was announced

From the @imagine post:

  • Video 1.5 Lite is live in the Grok Imagine API.
  • The account calls it the workhorse for text-to-video and image-to-video.
  • Stated prices are $0.02 per second at 480p, $0.03 per second at 720p, and $0.14 per second at 1080p.
  • The post includes a video. This page does not host that file.

SpaceXAI docs, last updated 8 October 2026, name the model grok-imagine-video-1.5-lite. The video overview says it does text-to-video and image-to-video with lip-synced speech, clips of 1–15 seconds, and 1080p by upscaling 720p. The same page lists the same per-second prices. It recommends the lite model for simple videos, and grok-imagine-video-1.5 when references, voices, pinned frames, or native 1080p are needed. The lite column in that table does not list reference images, voice references, or keyframes.

Context

The docs page compares lite with grok-imagine-video-1.5, which it describes as native 1080p text-to-video and image-to-video, up to 14 reference images, up to 3 voice references, and pinned frames, at $0.08 / $0.14 / $0.25 per second for 480p / 720p / 1080p. Elon Musk’s reply says the lite model is automatically used by Grok Bot. The reply does not say when that routing started or whether users can choose the model.

Limits of this report

The @imagine post does not name rate limits, regions, or a consumer-app rollout. Docs list regions us-east-1 and us-west-2 and a 10 requests-per-second limit on the model page; this report does not add claims beyond those pages. Only the statements in the source post, the Musk reply, and the cited docs are reported.
