Grok Imagine 2.0 Ext API Features

A focused text-to-image workflow with explicit generation parameters

Text-to-Image Generation

Create images from a required text prompt. This model is designed for text-to-image requests and does not accept image inputs.

1–12 Images per Request

Set the image count from 1 through 12. For a simpler interface, the recommended choices are 1, 4, 8, and 12.

Seven Aspect Ratios

Choose 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, or 16:9 for square, portrait, landscape, and widescreen layouts.

Asynchronous Task Flow

A generation request returns a task ID. Poll the task endpoint until it reaches a completed or failed status.

Fixed Quality Mode

Use resolution=quality or omit the field. The quality mode is fixed and is not a selectable pixel-resolution tier.

URL Result Delivery

Completed images are returned as URLs. These URLs expire after 72 hours, so download or archive the files promptly.

Successful-Image Billing

Charges are based on the number of images actually delivered successfully, including when only some images in a multi-image request succeed.

Clear API Workflow

Create a task through /v1/images/generations, then query /v1/tasks/{task_id} to obtain its status and image URLs.

Grok Imagine 2.0 Ext FAQ

Answers about inputs, output count, aspect ratios, tasks, quality, URLs, and billing

What does Grok Imagine 2.0 Ext support?

It supports text-to-image generation only. Send a non-empty text prompt; image-to-image inputs, image URLs, and image-role inputs are not supported.

How many images can one request generate?

The n parameter accepts any integer from 1 to 12 and defaults to 1. A straightforward UI can offer the recommended choices 1, 4, 8, and 12.

Which aspect ratios are available?

The seven recommended ratio values are 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, and 16:9. Unsupported values such as 1:2, 2:1, 4:5, or auto should not be sent.

How do I receive generated images?

POST the request to /v1/images/generations, save the returned task ID, and poll /v1/tasks/{task_id}. When the task is completed, read the successfully returned image URLs from the result.

Can I select quality or download images later?

Quality is fixed: use resolution=quality or omit it, rather than selecting 1K, 2K, or 4K tiers. Results are URL-only, and the URLs expire after 72 hours, so save them in time.

How is a multi-image task billed?

Billing is based on the actual number of images delivered successfully. If fewer images succeed than requested, only the successful images are charged; failed tasks are not charged.
