Example outputs summary for Kling: Video O1

Benchmarks

Scores on standardized evaluations and this model’s own outputs on shared benchmark prompts. Higher percentages are better — and each rank shows where this model lands among the models evaluated on that source.

Benchmark outputs summary for Kling: Video O1

  • Traffic light: A fixed camera on a single traffic light against a plain grey sky. The light starts red, changes to green, and then changes to amber, in that exact order, each colour holding for a clearly visible moment. No other objects, no camera movement, no cuts. (Tied 22nd of 28 on this prompt)
  • Five candles: A fixed straight-on shot of five lit candles in a row on a dark table. The candles go out one at a time from left to right until all five are out. No hand or person visible, no camera movement, no cuts. (Tied 17th of 28 on this prompt)
  • Wrong-way escalator: A fixed shot of an empty upward-moving escalator. A single red rubber ball bounces down the escalator steps from top to bottom, against the direction of the escalator's movement, and exits the frame at the bottom. No people, no cuts. (Tied 24th of 28 on this prompt)
  • Frozen crowd: A busy pedestrian plaza in daylight where every single person stands perfectly still like a statue for the entire clip. Only the flags on the buildings move in the wind. No person moves at all, not even slightly. Fixed camera, no cuts. (Tied 4th of 28 on this prompt)
  • Sign stays readable: A slow steady dolly toward a shop window sign reading exactly "OPEN 7 DAYS - COFFEE & BAGELS - EST. 2003". The text stays sharp, correctly spelled and unchanged for the whole clip as the camera approaches. No other text in the frame. (Tied 13th of 28 on this prompt)
  • Glass of water: A fixed close shot of a full glass of water on a wooden table. A rolling orange bumps into the glass. The glass tips over away from the camera, water spills across the table and spreads outward, and the empty glass rolls slightly and comes to rest. No hands, no cuts. (Tied 15th of 28 on this prompt)
  • Domino run: A fixed side-on shot of exactly eight upright black dominoes in a straight evenly spaced row on a white surface. The leftmost domino tips right and the whole row falls in a single left-to-right chain until all eight are flat. No hands after the start, no cuts. (Tied 7th of 28 on this prompt)
  • Mirror walk: A fixed shot of a large wall mirror in a bright dance studio. A man in a green t-shirt walks from left to right in front of the mirror. His reflection matches his movement exactly, mirrored, for the entire clip. No cuts. (Tied 4th of 28 on this prompt)
  • Behind the pillar: A fixed camera on a wide walkway with a single thick concrete pillar in the middle. A woman in a yellow raincoat walks at a steady pace from the left edge to the right edge, passing behind the pillar. She is briefly hidden, then reappears on the other side wearing exactly the same clothes, and exits frame right. No cuts. (Tied 15th of 28 on this prompt)
  • Steaming mug: Thin steam rises from the coffee and drifts slowly to the right. Everything else holds still: the mug and its painted design, the table, the background, the lighting and the framing stay exactly as in the reference. Static camera. No cuts. (Tied 1st of 27 on this prompt)
  • Walk out: The person from the reference turns and walks out of the frame to the right. Their face, hair and clothing stay exactly as in the reference until they exit. The background does not change. No cuts. (Tied 1st of 26 on this prompt)
  • Continuous shot: A single continuous shot, no cuts, orbiting exactly once, slowly, around a stone statue of a horse in an empty courtyard. The statue stays centred the whole time and the camera ends where it started. Nothing else enters the frame. (Tied 2nd of 28 on this prompt)

Providers

This model is hosted by one provider. OpenRouter forwards every request to it directly — no routing decisions to make.

Performance

Throughput is how fast the model writes (tokens per second — higher is better). Latency is total round-trip time (lower is better). TTFT is time-to-first-token — how long before you see anything appear (lower is better).

Uptime

Uptime is the percentage of the past 3 days that at least one provider was responding to requests. Availability is the percentage of time that inference was successfully served. OpenRouter continuously monitors and uses the next-best provider when one returns an error.

Apps

Public apps that send the most traffic to this model. Good signal for what real production workloads look like — and a hint at which use cases this model is best suited for.

Activity

Token volume and request traffic to this model over time.

API

Drop-in code to call this model. OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. The only thing that changes between models is the model slug below.

When an error occurs in an upstream provider, we can recover by routing to another healthy provider, if your request filters allow it. You can access per-provider uptime data programmatically through the Endpoints API. Learn more about our load balancing and provider routing options.
