Introducing the Gen-4 Image API

Earlier this month, we released Gen-4 References, our most flexible and general image generation model yet. It became one of our most popular releases ever, with new use cases and workflows being discovered every minute.

Today, we’re making Gen-4 Image, including References, available via the Runway API, allowing anyone to integrate its powerful multimodal generation capabilities directly into their apps, products, platforms and websites.

“Runway’s Gen-4 Image model marks a transformative step for creative teams. Adding this to Runway's API makes it possible to explore product looks and designs with unprecedented flexibility – scaling product visuals across scenes, characters and settings with consistent, repeatable precision. For brands and e-commerce, this unlocks a new level of efficiency in creating library photography and video content that’s both high-quality and endlessly adaptable.”
