Runway Rolls Out Gen-4.5 Video Model, Expands Full Access to All Paid Users

December 16, 2025

Details

  • Runway introduced Gen-4.5, its latest text-to-video model, on December 16, 2025.
  • The company claims this version offers unmatched cinematic realism, controllability, and expressiveness, surpassing the visual quality of Gen-4.
  • All paid plans now receive the full set of features, eliminating the need for extra credits or add-on purchases.
  • This update serves as an interim release before Gen-5, maintaining Runway’s pattern of semi-annual upgrades.
  • While technical details remain undisclosed, Gen-4.5 is available through both the web editor and API, enabling immediate use in creator workflows.
  • The launch bolsters Runway’s aim to attract filmmakers, advertisers, and game developers seeking premium AI video without conventional CGI resources.

Impact

This release strengthens Runway’s position against major players like OpenAI’s soon-to-launch Sora and Google DeepMind’s Imagen Video, intensifying competition in high-fidelity AI video. By including Gen-4.5 in all standard subscriptions, Runway makes a bold move against startups that restrict advanced models to higher price points. The broader access to photorealistic video could prompt regulatory attention and encourage a shift from traditional VFX to AI-powered tools in the coming years.
