State-of-the-art video generation across quality, cost, and latency.

Grok Imagine API Performance and Benchmarks Video Generation Video Editing What our partners are saying Get Started

A world-class video generation model.

A breakthrough video editing model.

We're excited to unveil the Grok Imagine API, a unified bundle of powerful APIs designed for end-to-end creative workflows. Grok Imagine is our most powerful video-audio generative model yet. Bring an image to life, start from a simple text prompt, or even refine a complex cinematic sequence.

Video generation

Grok Imagine has best-in-class instruction following capabilities.

Video editing

Restyle scenes, add/remove objects, and control motion.

Performance and Benchmarks

We engineered these models to deliver high-quality, native video-audio generation on par with today's top providers, while also optimizing latency, concurrency, and cost—refined through multiple rounds of close partner feedback. One message came through consistently: quality alone is not enough if latency and cost make iteration painful. By improving speed and economics, we enable developers, creative teams, and enterprise workflows to explore multiple directions in parallel—converging faster through rapid, cost-effective experimentation.

** We evaluated latency using 10 identical prompts, with each prompt tested 10 times per model to account for variability in processing times. P50 latency in seconds are reported for videos generated at 720p resolution with an 8-second duration. We measured end-to-end API latency using a 1-second polling interval using fal.ai for all models except Veo (measured using Vertex API), Sora (measured using OpenAI API), and Grok Imagine (measured using the xAI API)

What our partners are saying

The Grok Imagine API is available on our partner platforms, alongside our own API.

Image 71: Fal logo "We are thrilled to partner with xAI. Grok Imagine API delivers outstanding video quality with native audio video generation, combining photorealistic realism, strong creative style, and an impressive level of control."

Image 72: ComfyUI logo "The ComfyUI team gravitates strongly toward retro anime and cyberpunk aesthetics, and Grok performs exceptionally well in both text-to-image and image-to-video generation for these styles."

Image 73: Invideo logo "Grok is awesome because it helps bring the craziest ideas to life. At a video level grok brings visuals to life with accuracy and fluidity to actions that are prompted as well as to create visuals that are creatively restrictive to make using other models.The Addition of sound and dialogue further help in bringing visuals to life. "

Image 74: Flora logo "Imagine API is great at fast, high-quality visual ideation. It’s particularly strong at capturing scene-level style, mood, and physical realism, making it a great fit for early creative exploration and rapid iteration!"

Image 75: HeyGen logo "We've been integrating Grok into our Video Agent at HeyGen. With Grok's latest video model, you can just prompt edits directly for quick tweaks, empowering our users to iterate on clips in minutes instead of completely leaving it to luck. Excited to see more capabilities unlock from Grok."

Start building with Grok Imagine API today! We offer:

  • APIs and SDKs for seamless integration
  • Tutorials to jumpstart Grok Imagine projects
