xAI 发布 Grok Imagine API，Artificial Analysis 文生视频排名列第 1

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.

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)

* Human raters conducted side-by-side comparison on IVEBench comprising of a diverse database of high-quality source videos, spanning seven semantic dimensions, and covering varying video lengths (each including a prompt and input video, and evaluating a single generated video). All comparisons were done at 1280 x 720 resolution.
