Model Comparisons

vs Veo 3.1: Kling excels in character lip-sync and native audio for dialogue-heavy clips, while Veo prioritizes cinematic editing workflows and ambient sound. Kling offers better value at lower per-second costs, making it ideal for performance-driven content over Veo's frame control.

vs Sora 2: Kling provides granular motion control and audio co-generation superior for short, precise animations, unlike Sora's focus on long-form realism. Benchmarks show Kling's edge in prompt fidelity for product and portrait tasks, though Sora handles complex narratives better.

vs Wan 2.5: Kling delivers higher fluidity and 1080p polish with integrated audio, surpassing Wan's open-source speed in professional visuals. It wins for commercial use cases like portraits due to better consistency, while Wan suits cost-sensitive bulk generation.

Use cases

  • Portraits: Animate faces with expressive lip-sync and subtle head movements for social media avatars or personalized videos.
  • Product Shots: Add rotation, lighting shifts, and SFX to showcase items dynamically in e-commerce promos.
  • Scenes: Bring landscapes or concepts to life with camera sweeps and ambient audio for mood boards or ads.
  • Marketing: Create brand-consistent clips by swapping elements without reshoots.
  • Prototyping: Use draft modes for rapid VFX concepts, 20x faster than traditional rendering.

headers = {"Authorization": "Bearer " + AIMLAPI_KEY}
job = requests.post(
    "https://api.aimlapi.com/v2/video/generations",
    headers=headers,
    json={
      "model": "kling-video/v2.6/pro/image-to-video",
      "prompt": "A serene timelapse of clouds over a mountain range"
    },
).json()
gid = job["id"]

while True:
    res = requests.get(f"https://api.aimlapi.com/v2/video/generations?generation_id={gid}", headers=headers).json()
    if res.get("status") in ("completed", "error"):
        break
    time.sleep(5)
print(res["video"]["url"])
const headers = {
  Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
  "Content-Type": "application/json",
};
const job = await (await fetch("https://api.aimlapi.com/v2/video/generations", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "model": "kling-video/v2.6/pro/image-to-video",
    "prompt": "A serene timelapse of clouds over a mountain range"
  }),
})).json();

let res;

  await new Promise((r) => setTimeout(r, 5000));
  res = await (await fetch(`https://api.aimlapi.com/v2/video/generations?generation_id=${job.id}`, { headers })).json();
} while (!["completed", "error"].includes(res.status));
console.log(res.video.url);
# submit the generation — the response contains the job "id"
curl -X POST https://api.aimlapi.com/v2/video/generations \
  -H "Authorization: Bearer $AIMLAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"kling-video/v2.6/pro/image-to-video","prompt":"A serene timelapse of clouds over a mountain range"}'

# then poll until status is "completed" — video.url holds the result
curl "https://api.aimlapi.com/v2/video/generations?generation_id={id}" -H "Authorization: Bearer $AIMLAPI_KEY"
