Runway has recently updated their iOS app with several new features. The home page now includes an infinite video feed and users can generate new videos using the Gen3 alpha model, which was previously limited to Gen2.
With the public release of the Gen3 alpha, the home feed features pre-selected videos generated by Gen3. However, user-generated videos do not yet appear in this feed, though this functionality may be added in the future.
In the Create tab, users will find the new Gen3 option. Currently, this feature supports only text-to-video generation, not image-to-video. Users need credits and a pro subscription to use it.
In summary, Runway is a company that develops AI-generated video models. Their latest release, Gen3, was initially available on their website and is now also accessible via the mobile app.
