Runway's Gen-4.5 just set a new standard for AI video
Runway's new Gen-4.5 model is officially the top performer in text-to-video AI, outscoring Google's Veo 3 and OpenAI's Sora 2 Pro on industry benchmarks.
If you're into creative tools or making content, this is a pretty big deal.
What makes Gen-4.5 special?
Gen-4.5 can turn detailed prompts—including multiple actors and tricky camera moves—into sharp, realistic short videos fast.
It nails things like object weight, hair movement, and fabric textures, whether you want photorealism or animation vibes.
Tech behind the magic (and some limits)
Built with NVIDIA's latest GPUs, Gen-4.5 keeps motion smooth across scenes and is available on all Runway plans—so anyone can try it out.
Just know it sometimes struggles with cause-and-effect in scenes or keeping objects consistent throughout a video, and it has a slight "success bias" that might make results look too perfect at times.
