Score Breakdown
The Good and the Bad
What we like
- +Gen-4.5 holds #1 on Artificial Analysis text-to-video leaderboard (1,247 Elo as of 2026-04) -- ahead of Kling, Pika, Runway Gen-4, and Veo 3.0
- +Gen-4 Turbo ships native 4K output (Gen-3 topped out at 720p native / 4K upscale)
- +Full creative suite -- not just text-to-video but also inpainting, motion brush, image-to-video, video-to-video
- +Motion and physics are substantially improved over Gen-3 -- fewer hand/face distortions
- +The web editor is professional-grade with timeline, layers, masking
- +Available on all paid plans (Standard / Pro / Unlimited) -- Gen-4.5 isn't gated to top tier
What could be better
- −Credits still burn fast at premium resolutions -- a 4K Gen-4.5 clip can cost 100+ credits
- −Generation times are longer at 4K; lower-resolution output is much faster
- −Free tier is still basically a demo -- 125 credits gets you maybe 2-3 clips
- −Generated videos max out at about 10 seconds before quality degrades, same as Gen-3
- −Competition is closing -- Kling 3.0 and Veo 3.1 are both credible alternatives at similar price points

Known Issues
- Gen-4.5 released 2025-12-01 (replacing Gen-3 Alpha as flagship). Native 4K output via Gen-4 Turbo, substantially improved motion/physics, #1 on Artificial Analysis T2V leaderboard at 1,247 Elo. If your stack was pinned to specific Gen-3 behaviors, audit before upgrading -- some generation quirks have changedSource: runwayml.com/research, CNBC, Artificial Analysis · 2025-12
- Gen-4.5 still struggles with multi-character scenes where characters interact -- tends to blend features or lose one character mid-shot. Single-character clips are where it shinesSource: Reddit r/runwayml, hands-on testing · 2026-04
- Credit costs for 4K generation are meaningfully higher than 720p -- a 10-second 4K Gen-4.5 clip can cost 100+ credits vs ~50 credits at 720p. Budget for resolution accordinglySource: Runway pricing docs, community reports · 2026-04
Best for
Video creators, filmmakers, and agencies who need top AI video quality with the full creative suite (inpainting, motion brush, video-to-video). Gen-4.5 at #1 on the Artificial Analysis leaderboard makes it the benchmark pick for professional work in 2026.
Not for
Casual users or anyone on a tight budget. Credits disappear fast (especially at 4K), and the free tier barely lets you try it. For experimentation, Pika or Kling at similar price points are more forgiving.
Our Verdict
Runway remains the professional-tier pick for AI video in 2026. Gen-4.5 (shipped 2025-12-01) holds #1 on Artificial Analysis's text-to-video leaderboard at 1,247 Elo, with native 4K via Gen-4 Turbo and meaningful improvements in motion and physics over Gen-3. The creative suite -- inpainting, motion brush, video-to-video -- is still the widest in the market. Downsides are unchanged from Gen-3: credits burn fast (worse at 4K), 10-second clip cap, competition from Kling 3.0 and Veo 3.1 is tightening. If you need the best available quality or the full creative toolset, Runway. If you're budget-conscious or experimenting, Pika or Kling first.
