Grok Imagine API Now Available on Mobbi: Create AI Videos & Images with xAI's Aurora Engine

What is Grok Imagine?

xAI has officially launched the Grok Imagine API, and we're excited to announce it's now available on Mobbi. Grok Imagine is xAI's most powerful video-audio generative model, built on their proprietary Aurora engine. Unlike traditional diffusion-based models, Aurora uses a unified multimodal architecture that processes text, audio, and visual data simultaneously—delivering superior temporal consistency and native audio-video synchronization.

According to third-party evaluations from Artificial Analysis and LMArena, Grok Imagine ranks favorably against Google's Veo 3.1 Fast, Veo 3, and OpenAI's Sora 2 in text-to-video benchmarks. In video editing benchmarks, Grok Imagine posted a 64.1% overall win rate against Runway Aleph in human-rated side-by-side comparisons. This makes it one of the top-performing AI video models available today.

Key Features of Grok Imagine on Mobbi

Grok Imagine brings several groundbreaking capabilities to Mobbi users. The standout feature is native audio-video synchronization—every generated video includes perfectly matched background audio, ambient sounds, and music without any additional editing. This eliminates the tedious post-production step of syncing audio to your AI-generated videos.

The Aurora engine delivers exceptional instruction following. You can restyle scenes, add or remove objects, and control motion with natural language prompts. Whether you're creating a medieval knight walking through a mystical forest or a product showcase with dramatic lighting, Grok Imagine understands complex creative directions.

• Video resolution: 480p and 720p output options
• Duration: 1-15 seconds per generation (default 6 seconds)
• Frame rate: Smooth 24 fps output
• Aspect ratios: 16:9, 9:16, 4:3, 3:4, 1:1, 2:3, 3:2, and auto
• Native audio generation: Synchronized sound with every video
• Image-to-video: Bring any still image to life with motion
• Text-to-video: Generate complete videos from text descriptions
• Video editing: Modify existing videos with AI-powered edits

Image Generation with Aurora

Beyond video, Grok Imagine also powers stunning AI image generation. Built on the same Aurora architecture, Grok Imagine creates photorealistic images up to 1024×1024 resolution from text prompts. The model emphasizes visual fidelity and stylistic consistency—perfect for creating cohesive visual content across your projects.

Aurora's autoregressive approach differs fundamentally from diffusion models like Stable Diffusion or DALL-E. By processing visual tokens sequentially, Aurora maintains better compositional coherence and handles complex scenes with multiple subjects more reliably. This makes it particularly strong for product photography, character design, and scenes requiring precise spatial relationships.

How Grok Imagine Compares to Other Models

With Grok Imagine joining our lineup alongside Sora 2, Kling AI, Veo, Hailuo, and others, Mobbi now offers the most comprehensive selection of AI video models in one platform. Each model has unique strengths: Sora 2 Pro excels at long-form storytelling and cinematic quality, Hailuo delivers fast iterations at lower cost, and now Grok Imagine brings best-in-class audio synchronization and competitive quality.

For creators who need videos with sound—product demos, social media content, explainer videos—Grok Imagine eliminates the audio production bottleneck entirely. The 50% frame rate improvement in version 0.9 (up to 24 fps from 16 fps) also means smoother, more professional-looking motion compared to earlier releases.

Getting Started with Grok Imagine on Mobbi

Using Grok Imagine on Mobbi is straightforward. Head to our Text to Video or Image to Video tools and select "Grok Imagine" from the model dropdown. Write your prompt describing the video you want to create—be specific about subjects, actions, camera movements, and mood. The Aurora engine understands natural language, so prompts like "A golden retriever running through autumn leaves, warm sunset lighting, cinematic slow motion" work beautifully.

For image-to-video, upload any still image and describe how you want it to animate. Grok Imagine excels at preserving the composition and identity of your source image while adding fluid, believable motion. This is perfect for animating product photos, bringing illustrations to life, or creating dynamic versions of existing artwork.

Pricing and Availability

Grok Imagine is available to all Mobbi users starting today. Video generation costs vary based on duration and resolution, with a 6-second video at 720p costing approximately 15 credits. Image generation costs 5 credits per image. Premium and Pro subscribers benefit from priority processing and faster render times.

Partner integrations are also live through fal.ai, ComfyUI, InVideo, Flora, and HeyGen—but Mobbi offers the advantage of accessing Grok Imagine alongside all other major AI video models in one unified platform with consistent pricing and workflow.

What's Next for AI Video on Mobbi

The addition of Grok Imagine represents our commitment to giving creators access to the best AI tools available. xAI continues to iterate rapidly on the Aurora architecture, with improvements released regularly since the original beta in August 2025. We'll automatically update to new Grok Imagine versions as they become available.

Whether you're a content creator scaling video production, a marketer producing ads at scale, an educator creating engaging materials, or an artist exploring new creative possibilities—Grok Imagine opens up new workflows that weren't possible before. The combination of quality, speed, and native audio makes it a compelling choice for your next project.
