RunwayML AI Models: All Versions Compared
Professional AI image generation tools from RunwayML
Runway is Runway's AI video generation suite — built on the Gen model series with professional-grade character consistency, 4K output, and physically accurate motion. From Gen-4.5's realistic weight and momentum simulation with native audio to Gen-4 Turbo's 10-second clips in 30 seconds, every Runway model available on AI Compare Hub can be tested and compared against other leading AI video models, for free.
What you can create with Runway's models
-
Character-consistent video across scenes
Gen-4 and Gen-4.5 use reference images to maintain a character's visual identity across multiple shots and camera angles. Generate scene after scene featuring the same person, creature, or object without re-prompting to rebuild consistency.
-
Cinematic 4K video from text
Gen-4 generates at 4K resolution with smoother temporal motion and significantly better instruction following than earlier Runway models. Describe lighting, camera movement, and scene composition in natural language for precision cinematic output.
-
Fast video at reduced cost
Gen-4 Turbo generates 10-second clips in just 30 seconds at 5x lower credit cost than Gen-4. Use it for rapid concept exploration, high-volume content production, or any workflow where speed and efficiency matter more than maximum quality.
-
Physically accurate video with native audio
Gen-4.5 introduces unprecedented physical accuracy — objects and characters move with realistic weight, momentum, and force response — alongside native audio integration and multi-shot generation support in a single pass.
-
Multi-shot video sequences
Gen-4.5 supports multi-shot generation, allowing creators to build connected scenes with consistent characters and environments across multiple clips without manually chaining separate generations together.
Why creators choose Runway's models
-
Character consistency across scenes
Runway's reference-image system in Gen-4 and Gen-4.5 delivers some of the strongest character identity preservation available in AI video — making it the go-to platform for creators who need the same character to appear credibly across multiple shots and sequences.
-
Physical accuracy in motion Gen-4.5
Gen-4.5 simulates realistic physical behaviour — objects move with natural weight, momentum, and force. This level of physical grounding is rare in AI video models and makes Gen-4.5 the strongest Runway option for product launches, action sequences, and anything requiring believable real-world dynamics.
-
Speed variant at 5x lower cost
Gen-4 Turbo produces 10-second clips in approximately 30 seconds at a fraction of Gen-4's cost. For creative teams that need to generate many concepts or produce high volumes of social content, Gen-4 Turbo makes Runway's quality accessible at production scale.
-
Native audio integration
Gen-4.5 integrates audio directly into the generation pipeline — sound effects, ambient atmosphere, and dialogue are produced alongside the video output. No separate audio step required for basic sound design.
-
Adobe Firefly integration
Gen-4.5 is available inside Adobe Firefly via the Runway Aleph integration — extending Runway's video generation to millions of Creative Cloud users. Creators testing Runway on AI Compare Hub are evaluating the same underlying model available to Adobe's enterprise base.

Common questions
What AI models does Runway offer on AI Compare Hub?
Runway's model family on AI Compare Hub includes Gen-4, Gen-4 Turbo, and Gen-4.5 for AI video generation. Gen-4 delivers 4K output with superior character consistency and instruction following. Gen-4 Turbo is a speed-optimised variant at 5x lower cost. Gen-4.5 adds physical accuracy, native audio integration, and multi-shot generation.
What is the difference between Gen-4 and Gen-4.5?
Gen-4 (March 2025) delivered a major quality leap with 4K output, superior character consistency via reference images, smoother motion, and improved instruction following. Gen-4.5 (December 2025) raised the bar further by adding unprecedented physical accuracy — realistic weight and momentum in motion — alongside native audio integration and multi-shot generation support. Gen-4.5 is Runway's current highest-capability model.
What is Gen-4 Turbo?
Gen-4 Turbo is a speed-optimised variant of Gen-4 that generates 10-second video clips in approximately 30 seconds at 5x lower credit cost than Gen-4. It shares the same underlying architecture and character consistency features as Gen-4, making it the practical choice for high-volume production, rapid ideation, and workflows where speed and cost efficiency are priorities.
Which Runway model is best for AI video generation?
Gen-4.5 is Runway's most capable model — recommended for productions requiring physical accuracy, native audio, multi-shot consistency, and the highest visual fidelity. Gen-4 remains the best choice for 4K character-consistent video when audio is not required. Gen-4 Turbo is ideal for rapid concept exploration and high-volume content at significantly reduced cost.
Does Runway support character consistency across multiple video clips?
Yes — Gen-4 and Gen-4.5 both use reference images to maintain a character's visual identity across multiple shots and scenes. Provide a reference image of your character and Runway's models will preserve the identity, look, and style across different camera angles, environments, and lighting conditions.
