Grok Imagine is xAI's multimodal image and video generation model that converts text or images into short visual outputs with coherent motion and synchronized audio.
Model fixed to grok-imagine-text-to-image. Prompt required (max 5000). Aspect ratio options: 2:3, 3:2, 1:1, 16:9, 9:16.
Use this feature →Model fixed to grok-imagine-image-to-image. image_urls required (upload first), supports JPEG/PNG/WEBP with max 10MB per image. Prompt optional.
Use this feature →Model fixed to grok-imagine-text-to-video. Prompt required (max 5000). Configure aspect ratio, mode, duration (6/10), and resolution (480p/720p).
Use this feature →Model fixed to grok-imagine-image-to-video. Supports optional prompt and image_urls (up to 7). Configure mode, duration, resolution, and aspect ratio.
Use this feature →Model fixed to grok-imagine-upscale. Requires a completed task_id from Grok generation to upscale output quality.
Use this feature →Model fixed to grok-imagine-extend. Requires task_id and prompt, with configurable extend_at, extend_times (6/10), and resolution.
Use this feature →One model, two creative lanes: Grok Imagine unifies image generation and short video generation in one workflow. You can start from text, start from an image, or continue an existing result with upscale and extend.
Control with simplicity: Grok keeps parameter design compact but practical—aspect ratio, motion mode, duration, and resolution are enough for most social, marketing, and prototype scenarios without overloading the UI.
Text to Image
Model: grok-imagine-text-to-image (fixed) Prompt: Required, up to 5000 characters Aspect ratio: 2:3, 3:2, 1:1, 16:9, 9:16 Use cases: Concept art, ad key visuals, social thumbnails, product mockups.
Image to Image
Model: grok-imagine-image-to-image (fixed) Prompt: Optional image_urls: Required; JPEG/PNG/WEBP, max 10MB each Use cases: Style transfer, visual iteration, brand-consistent variations.
Text to Video
Model: grok-imagine-text-to-video (fixed) Prompt: Required, up to 5000 characters Parameters: aspect_ratio, mode (fun/normal/spicy), duration (6/10), resolution (480p/720p) Use cases: Motion concepts, short promos, social clips, storyboard previews.
Image to Video
Model: grok-imagine-image-to-video (fixed) Prompt: Optional image_urls: Optional, up to 7 images Parameters: aspect_ratio, mode, duration, resolution Use cases: Animate posters/illustrations, product hero animation, before-after reveal clips.
Upscale
Model: grok-imagine-upscale (fixed) task_id: Required, from completed Grok generation Use cases: Final-output enhancement before publishing or client delivery.
Extend
Model: grok-imagine-extend (fixed) task_id: Required prompt: Required Parameters: extend_at, extend_times (6/10), resolution (480p/720p) Use cases: Continue successful shots, add ending beats, expand narrative timing.
Creator workflows: Turn one idea into a full asset chain—key image -> animated clip -> upscale -> extended variant.
Marketing and ads: Produce fast campaign materials for product launches, seasonal activities, and paid social creatives.
E-commerce content: Build product hero images, lightweight motion ads, and platform-specific short videos.
Education and explainers: Create visual examples from text instructions, then extend or refine with image/video modes.
Rapid prototyping: Validate visual direction in minutes before entering heavy production pipelines.
Prompt support: Up to 5000 characters in key prompt-driven modes.
Image input formats: JPEG, PNG, WEBP; max 10MB per image.
Video controls: Duration 6s or 10s; resolution 480p or 720p; aspect ratio options include portrait, square, and widescreen.
Motion behavior: fun / normal / spicy modes for different movement intensity.
Output delivery: Generated media is returned as downloadable URLs suitable for preview and publishing workflows.
Image-first flow: Text to Image or Image to Image -> pick best variant -> optional Upscale -> export.
Video-first flow: Text to Video or Image to Video -> choose motion mode and duration -> preview -> optional Extend -> export.
Iterative production: Reuse successful prompts and task IDs, then branch into multiple variants for A/B testing.
Team handoff: Use task IDs and fixed model endpoints to keep generation reproducible across teammates.
Prompt quality: Describe subject, environment, camera language, and timing explicitly for better motion coherence.
Mode selection: Use normal as baseline; fun for creative reinterpretation; spicy for stronger dynamics when compatible.
Resolution strategy: Use 480p for fast drafts and iteration; switch to 720p for final deliverables.
Duration strategy: 6s for punchy loops and ad snippets; 10s for clearer scene progression and storytelling.
Extend planning: Set extend_at at a visually stable frame and use continuation-focused prompts to reduce jump cuts.
Unified image + video stack: No tool switching between still generation and short-motion generation.
Fixed model endpoints: Predictable behavior and easier API governance.
Practical controls: Small parameter surface with high day-to-day usability.
Scalable output paths: Supports direct generation, enhancement (upscale), and continuation (extend) in one suite.
Best for: Growth teams, social creators, designers, indie makers, and product teams needing fast visual iteration.
Grok on FuseAITools gives you a complete visual pipeline from static images to short videos, then quality enhancement and timeline extension—all under one model family. If you need fast iteration with practical controls and production-ready exports, Grok is a strong default choice.
