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. 🤯
