About this API
Runway is an AI creative tools company founded 2018 in New York, hailed as "Adobe of the AI era". Early image AI tools, pivoted to video generation in 2023 and became the leader. Latest Gen-3 Alpha model is in the first tier of text-to-video quality alongside OpenAI Sora, Google Veo, Luma Dream Machine. Runway has strong recognition in film/advertising professional markets — Oscar-winning Everything Everywhere All at Once used Runway tools; major ad agencies use Runway in prototyping phase. Runway web app is feature-rich (includes video editor), but API was only officially opened to developers in 2024 for product integration. Not cheap (credit-billed by duration + model); suitable for AI video SaaS rather than individual use.
