Runway AI: Models, Features & Alternatives

Some Runway models used to be available on getimg.ai, but not currently. Here's what you need to know about Runway's models, including the alternatives available via our Create video Action.

What is Runway AI?

Runway is an independent AI company, founded in 2018, best known for its Gen line of video generation models, some of which used to be available on getimg.ai. Runway continues on its own platform.

Runway's video model timeline

Runway's video models have moved through several generations. Here's the short version.

Gen-1 (2023) Restyled existing footage frame by frame.
Gen-2 (2023) Runway's first text-to-video: a prompt became a short clip.
Gen-3 (2024) Better realism and motion, plus first- and last-frame control.
Gen-4 (2025) Sharper subjects and more cinematic, consistent movement.
Gen-3 & Gen-4 Turbo Faster editions that were once available on getimg.ai.
Gen-4.5 (Dec 2025) Runway's current flagship: text and image to video.

Runway's current flagship: Gen-4.5

Runway's newest model, Gen-4.5, launched in December 2025. It generates video from a text prompt or a still image. It made a strong debut, but the AI video space moves fast: a wave of newer models has since overtaken it, and it no longer sits near the top of the independent rankings.

Gen-4.5 is not available on getimg.ai.

Text & image to video Generate from a prompt, or animate a still image as the first frame.
Short, HD clips Seconds-long clips at HD resolution; quality over length.
Overtaken since launch Strong at release, but current models now rank ahead of it.

Older Runway models: Gen-3 Turbo & Gen-4 Turbo

Two Runway models used to be available on getimg.ai: Gen-3 Turbo and Gen-4 Turbo. They're not here anymore, but here's what each one did.

Gen-3 Turbo First- and last-frame control; 16:9 or 9:16 clips up to 10 seconds (5 with a last frame) at 720p, 24 fps.
Gen-4 Turbo Smoother motion and an added 1:1 format alongside 16:9 and 9:16, without last-frame control.

Runway alternatives on getimg.ai

Runway is one video model among many now, and several current models are widely considered to be ahead of it. On getimg.ai you can generate with the ones at the top of the field today, no Runway account needed. Strong places to start:

Seedance 2.5 First- and last-frame control, reference images, native audio, and clips up to 30 seconds.
Gemini Omni Google's model: reference images and native audio, tuned for prompt accuracy.
HappyHorse 1.1 Reference images and native audio, with clips up to 15 seconds. Kling 3.0 Pro, FLUX 3 and MiniMax H3 are here too.

Video generated with HappyHorse 1.1.
