Runway Aleph 2.0 is an in-context video editing model from Runway. It applies text instructions and keyframe-guided edits across existing footage while preserving details that are not meant to change. It is suited for adding, removing, or replacing subjects and objects, changing backgrounds or outfits, relighting scenes, shifting weather or time of day, restyling footage, and expanding a shot to a new aspect ratio.
Runway Gen-4.5 is a video generation model from Runway for text-to-video and image-to-video workflows. It is designed for cinematic scene creation with strong motion quality, visual fidelity, and prompt adherence. The model can coordinate complex action sequences, detailed camera movement, precise event timing, and atmospheric changes, making it suited for narrative shots, product reveals, and controlled image animation.
