I always enjoy a chance to mess with AI video generators. Even when they're terrible, they can be entertaining, and when they pull it off, they can be amazing. So, I was keen to play with Runway's new Gen-4 model.
The company boasted that the Gen-4 (and its smaller, faster sibling model, Gen-4 Turbo) can outperform the earlier Gen-3 model in quality and consistency. Gen-4 supposedly nails the idea that characters can and should look like themselves between scenes, along with more fluid motion and improved environmental physics.
