Decision Axis
Where each model actually wins
Read this first. It turns the comparison into concrete tradeoffs instead of another feature table.
Lowest draft cost
Turbo starts at $0.05/s. Treat it as the iteration lane, not the final-quality row.
Native audio
Kling publishes native-audio pricing. Runway Gen-4 still needs separate audio work.
Longer generation
Kling reaches 15 seconds. Runway Gen-4 Video is a 5 or 10 second workflow.
Motion control
Runway wins when Motion Brush, fixed seed, and editor handoff are the reason you are choosing it.
1080p generation
Kling provider rows cover 720p-1080p. Runway Gen-4 outputs 720p before upscale.
4K delivery
Runway can upscale to 4K as a separate action. That is delivery support, not native 4K generation.
Evidence Notes
What the data can and cannot prove
These notes keep benchmark and workflow claims separated, which matters for this pair.
Benchmark
Public arena context
1243 ELO, rank 4 (2026-04-14) for Kling v3 Pro. No separate Gen-4 arena score is published here; Runway Gen-4 uses the Gen-4.5 family reference only as context.
Mode mismatch
These models are not the same shape
Kling is a text/image-to-video generator with native audio paths. Runway Gen-4 is image-required for Gen-4 Video, with Aleph as the video-to-video edit path.
What matters
Price is the second filter
The cheapest row is only useful after the workflow is right. Audio, duration, Motion Brush, and 4K upscale change the real production cost.
Price Lanes
Compare the production paths, not one row
The row you should use depends on whether the job needs audio, edit mode, provider confidence, or a specific delivery tier.
