## AI overview

OpenRouter compares Veo 3.1, Seedance, Kling, and Grok Imagine Video on duration, resolution, frame control, audio, reference inputs, and pricing. It explains how to choose a model and submit an image-to-video job through the API, including TypeScript SDK code and asynchronous polling. The article also notes that disabling automatic retries for paid submissions can help avoid duplicate generation jobs.

## Source excerpt

If you already have the image a video should start from, the model choice comes down to what has to happen after that frame. This post compares the Veo 3.1, Seedance, Kling, and Grok Imagine Video lines on duration, resolution, first-frame and last-frame control, generated audio, reference inputs, and current per-second price, then shows how to submit an image-to-video job with the TypeScript SDK.
