Why creators choose Grok Imagine 1.5

Grok Imagine 1.5 is xAI's workhorse video model. It's fast, it handles text and image input equally well, and sound is always included. When you need a reliable, affordable generation model that handles a variety of tasks and platforms, Grok Imagine 1.5 delivers. It's built for practical production use, not just experimentation.

Fifteen seconds in one clip

Most fast models max out at 8 seconds. Grok Imagine 1.5 goes to 15, so a longer scene, a product demo, or a narrative beat can happen in a single generation without seams or cuts. That 15-second window is long enough for a complete thought or action sequence.

Seven different aspect ratios

Shoot 16:9 for landscape, 9:16 for vertical, 1:1 for square, or four more options in between. Different platforms need different shapes, and Grok Imagine 1.5 handles them all from the same prompt. This makes it efficient for creators managing multiple social feeds or platforms.

Native sound in every pass

No separate audio generation, no sync headaches. Grok Imagine 1.5 makes the sound and picture together. The audio is semantically linked to the visuals, so dialogue, ambient sound, and effects match the action.

Fast iteration at scale

When you're making dozens of clips, speed matters. Grok Imagine 1.5 generates in seconds, not minutes. Batch work becomes feasible. For creators on tight schedules or managing high-volume content, this is a practical advantage.

How to use Grok Imagine 1.5 in Craze

1. Start a project and describe the video or upload reference images. If you have video as direction, add that too.
2. Say you want Grok Imagine 1.5. Craze runs the model when you ask for it by name. If you don't name one, Craze shows compatible models with their costs.
3. Craze generates the clip at your chosen resolution and aspect ratio, with sound included.
4. Review in the editor. Regenerate shots that miss or carry on editing.

Grok Imagine 1.5 capabilities

Grok Imagine 1.5 supports text-to-video, image-to-video, and reference-video generation. You describe a scene in words and it generates from scratch. You provide an image and it animates it. You provide a video reference and it applies a style or creative direction to extend the concept.

The model preserves fine detail across the full 15 seconds and writes to natural physics. Motion looks realistic, objects move according to real-world principles, and light behaves correctly. Reference images work to anchor composition, character, or style, and Grok Imagine 1.5 holds that reference throughout the generation.

Grok Imagine 1.5 generates up to 1080p at multiple aspect ratios. Craze runs the model when you ask for it by name, generating clips with sound always included. No separate audio pass needed.

Grok Imagine 1.5 pricing

You pay per second of video. $0.085 per second of video, with pricing that changes by resolution. Clips can range from 1 to 15 seconds. The cost calculator on this page shows exact rates.

Aspect ratio selection and reference images don't change the rate. Sound is included in every generation. Longer clips cost more, but the 15-second window means you can often get a complete idea in one shot without needing multiple generations to stitch together.

Who Grok Imagine 1.5 is for

Fast-paced production schedules

When you're making ten clips a day, speed is a feature. Grok Imagine 1.5 turns clips around quickly without forcing you to compromise.

Multi-platform content

One shoot, many aspect ratios. Grok Imagine 1.5's aspect ratio flexibility means you can fill Instagram, TikTok, and YouTube all from the same brief.

Narrative video and storytelling

Fifteen-second clips are long enough for a short scene or narrative moment. Use Grok Imagine 1.5 to build a sequence with full context in each clip.

Grok Imagine 1.5 vs other models

Grok Imagine 1.5 is the speed choice for versatile video generation. It generates fast, handles text and images equally well, supports multiple aspect ratios for different platforms, and always includes sound.

For maximum resolution and 4K work, see Veo 3.1, which reaches broadcast resolution and supports 8-second clips. For character consistency and complex references, see Gemini Omni Flash, which excels at keeping characters consistent across shots. For video extension only, see Grok Imagine, which is specialized for locking to camera motion in existing footage.

Grok Imagine 1.5 is the practical choice for creators who need speed, versatility, and quick turnaround on multiple aspect ratios.
