Grok Imagine 1.5 API questions

How fast is the Grok Imagine 1.5 API? expand_more

Around 30 seconds per generation, tied with Seedance 2 as the fastest option on VideoGenAPI. For comparison, Sora 2 averages 110 seconds and Kling 3 around 250.

Close to it. At roughly 30 seconds it is fast enough for a user to wait through with a progress indicator, which is what makes it viable for chatbot video replies and live preview interfaces.

What are the limits of Grok Imagine 1.5? expand_more

Clips run 5 to 10 seconds at up to 1080p. It is built for speed rather than maximum fidelity, so use Sora 2 or Veo 3.1 when a client is paying for the polish.
