The anime-style video highlights Gen-3's ability for character reference and fine-grained temporal control (the ability to precisely manage and manipulate the timing and sequence of events), which is evident in its consistent artistic direction and smooth camera movements. The attention to small details, like the movement of water and reflections, adds to the realism and engagement.

When Will Runway Gen-3 Launch? 

After a short alpha-testing phase, Runway has launched Gen-3 Alpha for users to try. At the time of updating this article, you can now sign up for an account and subscribe to start using the tool.

How Much Will Runway Gen-3 Cost?

The Gen-3 model is currently only available to paid subscribers. Runway uses a pay-as-you-go model based on GPU usage, enabling access to the necessary computational power without major hardware investments. 

There are several usage tiers - a ‘Basic’ tier that is free (with limited usage credits), with ‘Standard’ ($12/month), ‘Pro’ ($28/month), and ‘Unlimited’ ($76/month) options also available.

Runway Gen-3 vs. Sora AI

Runway Gen-3 and OpenAI’s Sora are two of the most advanced models in AI-driven video generation. 

Runway Gen-3 is built on visual transformers, diffusion models, and multimodal systems to achieve high fidelity and temporal consistency. The diffusion models refine images from noise iteratively, resulting in realistic, high-definition visuals. Gen-3 enables functionalities like text-to-video and image-to-video.

Prompt: Close-up shot of a living flame wisp darting through a bustling fantasy market at night.

The lifelike movement of the flame, its interaction with surrounding objects, and the realistic shadows and reflections demonstrate the model’s capability to produce high-resolution content with detailed frames, contributing to a cinematic quality of the output.

Comparison from a technical perspective 

Sora, developed by OpenAI,  uses a diffusion model technique similar to Midjourney, starting with noise and refining it step-by-step until coherent scenes emerge. Built on a Transformer architecture, Sora represents videos as collections of data patches, learning complex mappings between textual descriptions and visual manifestations frame-by-frame. 

Sora can handle diverse visual data across various durations, resolutions, and aspect ratios. Sora AI excels in dynamic scene creation with intricate details, demonstrating an acute understanding of lighting, physics, and camera work. 

The model can generate long-form videos with coherent transitions, in detailed and expressive visual storytelling. Sora AI has robust safety protocols, such as adversarial testing and detection classifiers, avoiding the risks related to misinformation, bias, and harmful content.

Runway's Gen-3 Alpha, the first in a series of new models, focuses on improving fidelity, consistency, and motion over its predecessor. It's trained on a new infrastructure for large-scale multimodal learning, combining video and image training. Gen-3 Alpha powers various tools, including text-to-video, image-to-video, and text-to-image, as well as control modes like motion brush and advanced camera controls (more on these later).

Both models aim to push the boundaries of AI-driven video generation: Runway Gen-3 focuses on developing general world models that simulate objects based on realistic human behavior and complex data, while Sora AI continues with its long-form generation and physics simulation capabilities.

Comparison of results 

Runway Gen-3 excels in producing high-fidelity, detailed, and contextually rich videos compared to existing Image generator models such as DALL-E, Midjourney, and Stable Diffusion. Leveraging advanced algorithms such as visual transformers and diffusion models, Gen-3 achieves remarkable temporal consistency, ensuring stable and realistic video frames.

Gen-3 incorporates a safety method, as part of the responsible AI concept, technically a system based on the C2PA standard, adding metadata to videos that indicate their AI origin and creation details​.

Implementing safety measures is becoming increasingly crucial for corporations, governments, and startups, whether open or closed source. Business model strategies of AI-driven organizations must prioritize AI safety concerns.

Sora also demonstrates exceptional video generation capabilities. Sora utilizes a diffusion model technique similar to Midjourney, starting with noise and refining it step-by-step to create coherent and vibrant scenes. 

Also built on transformer architecture, Sora represents videos as collections of data patches, enabling it to process diverse visual data efficiently across various durations, resolutions, and aspect ratios. Sora is strong in creating dynamic scenes with intricate details, showcasing a deep understanding of lighting, physics, and camera work. It can generate long-form videos with coherent transitions.

This vision is supported by significant investments, such as the recent $141 million funding round, which will be used to scale research efforts and develop new, intuitive product experiences​.

Upcoming features and potential future updates to Gen-3

Gen-3 Alpha is introducing several groundbreaking features that will enhance its usability and creative potential. Future updates will include more fine-grained control over video generation, allowing creators to specify details like structure, style, and motion with greater precision. It will be supported by Runway’s suite of tools: Text to Video, Image to Video, Advanced Camera controls, Directors Mode and Motion Brush, which enable users to generate complex and dynamic visual content from simple prompts.

General world models

General World Models (GWMs) represent an ambitious concept in AI research, aiming to create systems that can comprehensively understand and simulate the visual world and its dynamics across a wide range of real-world scenarios. 

Unlike previous world models limited to specific contexts, GWMs seek to build internal representations of diverse environments and simulate future events within them. This project faces several challenges, including generating consistent environmental maps, enabling navigation and interaction within these environments, and capturing both world dynamics and realistic human behavior. 

Current video generative systems like Gen-3 are seen as early, limited forms of GWMs. The development of more advanced GWMs could potentially revolutionize AI's ability to interact with and understand the physical world, marking a significant step forward in AI technology.

Runway's Suite of Tools

Text-to-video

With Runway's Text to Video tool, users can generate videos by typing a text prompt. Users can adjust various settings like fixed seed numbers, upscaling, and frame interpolation to enhance the video's consistency and resolution. Text-to-video is intuitive; by adjusting settings such as fixed seed numbers, upscaling, and frame interpolation, users can achieve consistent high-resolution outputs. The diversity of video styles is endless, from simple descriptions to complex scenes.

Image-to-video

The image-to-video tool transforms static images into dynamic videos. The process starts with the user uploading an image, then adjusting settings for enhanced detail and resolution. It’s an ideal tool for animating photographs and creating visual stories from still images.
