xAI opens Grok Imagine 1.5 Preview in the Imagine API

• xAI opened grok-imagine-video-1.5-preview in the API on June 3, and xAI's API preview post points to the official launch note, which says the model turns a single still image into video at up to 720p.
• The broader Imagine API, linked in xAI's API preview post, is positioned as one surface for image generation, video generation, editing, and restyling, with image output up to 2K, video up to 15 seconds, and pricing that starts at $0.02 per image.
• Early creator reaction landed fast: starks_arq's film-stack reaction framed Grok as ready for a filmmaking workflow, while ai_artworkgen's first-look post called the results "LEGIT."
• xAI also said on the same day that Grok models are available through Cloudflare AI Gateway, and Cloudflare's xAI provider docs show that existing xAI calls can be rerouted by swapping the base URL.

You can browse the launch post for the exact model slug, jump straight into the Imagine API page for try-on, product mockups, and restyling flows, and Cloudflare's Grok gateway docs are already live with the URL pattern for routing requests through AI Gateway. AmirMushich's addon mockup also shows the kind of lightweight idea-generation layer creators immediately started imagining on top.

The official launch note says grok-imagine-video-1.5-preview is an image-to-video model: you give it one still frame plus a motion prompt, and it handles camera movement, atmosphere, physics, and pacing. xAI says output runs up to 720p.

That is the practical shift here. Grok Imagine was easy to discuss as a model name, harder to slot into a production toolchain. API access turns it into something a studio, app team, or creative developer can actually wire into a workflow.

The Imagine API page, which xAI's API preview post links to, is broader than the preview announcement itself. It presents one API for several visual jobs:

• Text-to-image generation
• Text-to-video generation
• Image-to-video generation
• Editing and precision edits
• Restyling across different visual looks
• Virtual try-on for a person photo plus a clothing item
• Product placement and mockup generation

The same page lists the current envelope in concrete numbers: up to 2K resolution for images, up to 10 images per request, video clips up to 15 seconds, and pricing from $0.02 per image. It also leans hard into commerce and ad use cases, especially apparel try-on, product demos, and scalable product creative.

The same-day Cloudflare angle matters because it gives Grok models another production route besides calling xAI directly. According to Cloudflare's xAI provider docs, developers can keep using an xAI token and model name, then replace https://api.x.ai/v1 with https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/grok.

Cloudflare's docs also spell out the minimum setup: account ID, gateway name, active xAI API token, and the Grok model you want to call. For teams already standardizing traffic through AI Gateway for logging, caching, or rate controls, that makes Grok available through the same routing pattern.
