Frequently asked questions
What is Runway Gen-3 Alpha?
Runway Gen-3 Alpha is the third-generation video model from Runway. It generates up to 10-second clips from text or image prompts and is embedded in Runway's filmmaker-focused editing suite.
How is Gen-3 Alpha different from Sora or Veo 2?
Gen-3 Alpha is tuned for filmmakers with strong editing integrations, character consistency, and image-to-video. Sora and Veo 2 currently lead on absolute generation quality, but Runway's workflow around the model is the most mature.
How is Runway priced?
Runway sells monthly subscriptions (Standard, Pro, Unlimited, Enterprise) that include a pool of generation credits. The API bills per generation; clip cost depends on duration and resolution.
When is Runway the right choice?
Pick Runway when you want a full editing environment around video generation — roto, compositing, frame-interpolation, and green-screen all in one tool. For absolute quality or API-first workflows, consider Veo 2, Sora, or Luma Dream Machine.
