Any recos on video editors with exceptional art direction instincts, who are obsessed with AI and have taste you can't help but envy? I'd love to meet them.

Introducing our new frontier video model, Runway Gen-4.5. Previously known as Whisper Thunder (aka) David. Gen-4.5 is state-of-the-art and sets a new standard for video generation motion quality, prompt adherence and visual fidelity. Learn more below.

Gen-4.5 achieves an unprecedented level of physical accuracy and visual precision. Objects move with realistic weight and momentum. Surfaces behave the way they would in the real world. Laws of physics can be both observed or ignored, depending on your vision. Despite the big

Introducing Whisper Thunder aka Gen-4.5. Today, we are excited to share our new frontier model. Gen-4.5 was built by a team that fits onto two school buses and decided to take on the largest companies in the world. We are David and we’ve brought one hell of a slingshot.

I haven't had this much fun with a model. Ever. Whisper Thunder delivers every time. One of the parts I like the most is how steerable it is with movements, cameras, and super specific prompts. I made this music video in just under 2 hours. Enjoy!

Introducing Whisper Thunder, or Gen-4.5. It's the best video model in the world, able to handle very complex sequences of actions and events with amazing fidelity, and it's just so fun to use. Can't wait to make it available to everyone in the coming days. It's a validation of

Best model. Best team.

With Gen-4.5 you can achieve an unprecedented level of cinematic realism while still achieving novel creative concepts. The model is exceptionally good at generating objects that move with realistic weight, momentum and force. Even when suspended in zero gravity. Gen-4.5 early

Gen-4.5 offers an unprecedented level of visual fidelity and artistic range. Without the need for complex prompting the model can accurately light your scenes to achieve your desired mood and story with realistic light and shadow. Whether you're looking for clean studio set ups

Gen-4.5 can handle a wide range of aesthetics, from photorealistic and cinematic to "practical" puppetry, 3D animation, anime and more. All while maintaining a coherent visual language across your generations. So you can explore all possible worlds to tell all imaginable stories.
