Grok Imagine 1.5

Grok Imagine 1.5 is the new xAI video model. It films 1 to 15 second clips in 480p, 720p and 1080p from a description or your photos (up to 7). Strong motion, light and character acting.

You pay per second of the clip; each attached photo adds a small fee.

One model, grok-imagine-1.5 · ~2 min. The result follows the input fields (prompt, frames, references, video_mode, duration) — there are no separate «animate / edit» endpoints.

#Features

• nsfw_check — check before charge

#Price

• Price = per-second price × clip length, rounded up to $0.001. Charged when the task is created and fully refunded if it fails.
• Each attached photo adds $0.012.

#Media limits

Photos — public https or upload; video and audio — files/upload only.

#How the task is shaped

Upstream rejects aspect_ratio «auto» — text defaults to 16:9; with a photo the frame follows the photo.

#Parameters (field input)

#Examples

#Prompt only

#Create and result

1. POST /api/v1/jobs/createTask with model and input.
2. Poll GET /api/v1/jobs/recordInfo?taskId=… every 3–5 s (or a callback).

#Successful createTask (HTTP 200)

{
  "code": 200,
  "msg": "success",
  "data": {
    "taskId": "task_...",
    "task_id": "task_...",
    "status": "submitted"
  }
}

#Completed task (recordInfo)

{
  "code": 200,
  "msg": "success",
  "data": {
    "taskId": "task_...",
    "task_id": "task_...",
    "state": "success",
    "status": "completed",
    "costUsd": "0.384",

      "duration": 8
    }
  }
}

Aliases: task_id = taskId; status: pending / processing / completed / failed alongside state. Clip URL is in resultJson. size is an alias of aspect_ratio in input.

Photos can be any public https links or uploads via files/upload. Videos and audio — via files/upload only.
