Grok Imagine is xAI's multimodal AI image and video generation model. Its official website positions it as a free AI image and video generator, powered by xAI's Aurora engine. Its core slogan is "Imagine it, Grok creates it," meaning users only need to enter a prompt or a photo to generate photorealistic images and cinematic videos with synchronized audio.
In terms of use, Grok Imagine consolidates text-to-image, text-to-video, and image-to-video into a single platform, aimed at creators who need to quickly produce image and video content. The official website states that it can be used for advertising and marketing campaigns, client and agency work, social and YouTube monetization content, as well as products, merchandise, and print materials.
Main capabilities include: generating cinematic videos from text with natural motion and physics-aware rendering, with audio completed in the same generation; animating static images into dynamic videos with AI motion synthesis and built-in audio generation; multimodal input, with uploads of up to 9 images, 3 videos, and 3 audio files, freely combinable, up to a total of 12 files across modalities; referencing motion, effects, camera movement, characters, and scenes in uploaded content through natural language; video extension functionality that can smoothly extend existing videos, merge clips, or edit specific segments while maintaining continuity; and automatically generating scene-aware sound effects and background music synchronized with video content.
Generation features emphasized by the official website include: maintaining consistency of faces, clothing, text, scenes, and visual style throughout the video; precise motion replication; multi-shot storytelling; and clips ready for direct production use. Generated videos range from 1 to 30 seconds in duration and support multiple aspect ratios such as 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1. The Grok Imagine model itself supports up to 720p, while other video models in the same workspace can support up to 1080p.
In terms of usage, the official website provides a free entry point: registration grants free credits, and daily check-in allows manual claiming of 5–10 credits; the free tier includes the Grok Imagine model, text-to-image and image-to-image, text-to-video and image-to-video, more than 20 advanced AI models, and video downloads. Paid plans are annual only, advertised as saving 50% with annual payment, and are divided into three tiers: 3,000 credits/year for casual creators, 6,000 credits/year for daily creators, and 18,000 credits/year for advanced users and studios. All paid plans include commercial licensing, watermark-free video downloads, and unlock all 20 Multiple AI models (such as Flux 2, GPT Image, Imagen 4, as well as Sora 2, Veo 3, Kling 2.1, etc.), and includes video enhancement and video extension features; the advanced plan also includes priority email support. Content created under paid plans may be used for commercial purposes, with no watermark, no attribution requirement, and no additional fees. The official website also notes that credits may be insufficient to cover heavy usage.
Regarding limitations, the official website explicitly states: video input is limited to a maximum of 3 clips with a total duration not exceeding 15 seconds; videos generated by Grok Imagine are at most 720p. Other technical details, regional availability, refund policies, etc. not described in the materials are not provided for now.
