Runway Gen-4 is here: the next generation of AI video generation begins
AI video production reaches the next level
Runway has reached a significant milestone in AI-powered video generation with the release of Gen-4. The new model solves one of the biggest problems of previous AI video generators: the consistent representation of characters, objects and environments across multiple scenes. This development could fundamentally change the way films, advertisements and digital content are produced.

Gen-4 is the latest version of the AI video generation model from Runway, a leading company in the field of generative AI technology. It is an advanced system for generating videos with remarkable consistency and realism. The model was developed to bridge the gap between traditional video production and AI-powered content creation.
“Gen-4 is a significant step forward for fidelity, dynamic motion, and controllability in generative media,” Runway explains in its official announcement on X (formerly Twitter).
The new model is currently being rolled out to all paying users and promises to democratize video production by putting powerful tools in the hands of creators, regardless of their budget or technical knowledge.
The key features of Runway Gen-4
Character consistency with just one reference image
One of the most notable innovations of Gen-4 is its ability to generate consistent characters across different scenes, lighting conditions, and camera angles – all with just a single reference image. This has been one of the biggest challenges for AI video generators so far.
“Runway Gen-4 allows you to generate consistent characters across endless lighting conditions, locations, and treatments. All with just a single reference image of your characters,” says the official website.
Welcome to a new frontier of generative storytelling.

Object consistency in different environments
The same applies to objects: Gen-4 can place any object or motif in any desired environment while maintaining their visual integrity. This opens up new possibilities for product photography, film production and other visual media.
“Place any object or subject in any location or condition you need. Whether you’re creating scenes for longer narrative content or generating product photography, Runway Gen-4 makes it easy to generate consistently across different environments,” explains Runway.
Multiple perspectives of a scene
Another groundbreaking feature is the ability to generate different angles of the same scene. To create a scene, the user simply provides reference images of their subjects and describes the composition of the desired shot. Gen-4 does the rest, creating consistent shots from different perspectives.
Realistic physics and movement
Gen-4 is characterized by its ability to generate highly dynamic videos with realistic motion. The model simulates physical processes with remarkable accuracy, resulting in natural-looking interactions between objects and their environment.
“Runway Gen-4 represents a significant milestone in the ability of visual generative models to simulate real-world physics,” the company emphasizes.
Comparison with previous models
Gen-4 represents a significant step forward from its predecessors. While Gen-3 Alpha, released in June 2024, already expanded the length of generatable videos from just two to ten seconds, Gen-4 goes further by significantly improving consistency and coherence.
The earlier models treated each frame of a video as a separate creative task with only loose connections between them. Gen-4, on the other hand, seems to have solved this problem by way of a kind of “persistent memory” of visual elements. Once a character, object, or environment is established, the system can render it from different angles while maintaining its core attributes .
The competitive landscape
Runway is competing with other major players in the AI video generation space, including OpenAI and Google. However, what sets Runway apart is its focus on the needs of creatives and filmmakers.
While many competitors offer general video generation tools, Runway has sought an Adobe-like place in the industry. The company is focused on marketing to creative professionals such as designers and filmmakers, and has implemented tools designed to make Runway an enabler of existing creative workflows .
This strategy has helped Runway stand out from the competition and secure important partnerships such as the one with Lionsgate.
Future prospects
The introduction of Gen-4 could mark a turning point in AI-powered video production. With the ability to create consistent characters and environments, the vision of a fully AI-powered film production is moving closer to reality.
Runway itself is seeking a $4 billion valuation and hopes to reach $300 million in annual revenue this year. These financial ambitions underscore the company’s confidence in the potential of its technology.
However, Gen 4’s most profound impact may not be what it can create, but what it says about our future relationship with visual media. We are entering an era where the bottleneck in production is no longer technical skill or budget, but imagination and purpose. In a world where anyone can create any image they can describe, the most important question becomes: What is worth showing?
Bottom line: a new era of video production
Runway Gen-4 marks a significant advance in AI video generation. With its ability to create consistent characters and environments across different scenes, it solves one of the biggest obstacles to the use of AI in professional video production.
While the technology offers impressive possibilities, important questions remain about legal, ethical and economic implications. The way we answer these questions will largely determine how Gen-4 and similar technologies shape our visual culture.
One thing is certain, however: the video production landscape is rapidly changing, and Runway Gen-4 is at the forefront of that transformation.
