Runway Gen-4.5 is the new top-rated video model (1,247 Elo). It delivers SOTA motion quality, precise prompt adherence, and realistic physics—without sacrificing speed.
Runway is back at it with Gen-4.5. The competition in the AI video space has been getting pretty intense lately, and we can definitely expect even more coming soon.
It’s now hitting #1 on the Artificial Analysis leaderboard (1,247 Elo score), but beyond the rankings, a few things stood out to me:
Complex Instructions: It handles multi-step prompts (like specific camera moves + timing) much better now, rather than just generating a random pretty clip.
Physics: They’ve focused heavily on realistic weight and momentum.
Transparency: I really appreciate that Runway is open about the current limitations, like object permanence issues.
Also, they shared a short clip showing the evolution from Gen-1 to Gen-4.5. It’s wild to see the difference. It really shows how time flies and how far the boundaries of our imagination have been pushed in just two years. 🤯
The video quality is excellent! I’m looking forward to being able to make entire movies using AI. That would be really cool.
I’m not very technical, but the results look amazing. Is it easy for beginners to get good clips?
@RunwayML The AI video space is moving fast! Gen 4.5 improvements must be significant.
How does this compare to the previous version in terms of consistency and control?
Are creators finding it better for longer form content or still best for short clips?
Curious about the rendering time improvements.
I could see how our tool could elevate its creative storytelling by pairing with Runway’s AI video generation, so I’m definitely going to check out their launch and explore how this can work together.
Maybe I'll create a full movie and premiere it in a theater. It's that realistic. :) Really cool.
This looks huge. I’ve been following the evolution of AI video closely, and each step has been exciting but not quite enough for real use in my own projects. Gen-4.5 seems like a different tier completely, especially with the motion realism and speed improvements. I’m genuinely excited to dive in, try some ambitious shots, and see how it holds up in real creative scenarios. Lots of ideas brewing already.
It looks cool, maybe I missed it, but would be better if I could upload more than just one image.
