Kling AI

Kling AI is the text-to-video and image-to-video generator Kuaishou Technology launched in June 2024 and grew to over 22 million users by late 2025. Kuaishou Technology, listed on the Hong Kong Stock Exchange, runs Kling AI as a public-facing API and consumer product, with Kling 2.6 (December 2025) the first mainstream model to generate synchronised audio and video in a single pass and Kling 3.0 (February 2026) extending clip length and adding 4K image generation. The free tier hands out 66 credits a day, enough to test serious workloads before paying.

What Kling AI does:

• •Text-to-video at 1080p, 48 FPS generates up to 10-second clips on Kling 2.6 and 15-second clips on Kling 3.0, the longest single-pass output among mainstream video models.
• •Native audio in one pass Kling 2.6 generates the dialogue, sound effects, and music with the video itself, on par with Sora 2 and Veo 3.1.
• •Image-to-video animation upload a still and animate it with prompted motion, useful for product demos, character reels, and cinematic shots.
• •Elements (multi-image reference) combine up to 4 reference images for character consistency across scenes, the strongest single-character-reel feature in the category.
• •First and last frame control pin opening and closing frames so you can chain clips into longer continuous sequences without obvious cuts.
• •Kling 3.0 multi-shot logic chain-of-thought reasoning produces multi-shot scenes with consistent characters across cuts, multi-language audio, and correct lip-sync.
• •4K image generation (Kling 3.0) a new image model included on Ultra subscriptions, useful as the still input for image-to-video work.
• •REST API on Kuaishou's developer platform for studios that want Kling output baked into Remotion, n8n, or custom video pipelines, with usage-based billing.
• •iOS and Android apps with strong ratings 4.7 on the App Store and 4.54 on Google Play, with the same generation pipeline as the web app.
• •Free 66 credits a day the most generous free tier in the AI-video category, enough to try real workloads before subscribing.

Pricing:

• •Free $0/mo: 66 daily credits, web and mobile, sufficient for exploratory work and short demos.
• •Standard from $6.99/mo: monthly credit allowance, 1080p output, image-to-video and text-to-video on Kling 2.6.
• •Ultra $180/mo: full Kling 3.0 access, 4K images, longest clip lengths, priority queue, and early access to new models.

Limitations:

• •Ultra pricing rose 41% in 6 months Ultra moved from $128/mo in August 2025 to $180/mo by January 2026, so heavy users budget for further increases.
• •Mainland China product Kuaishou Technology is Beijing-based and the product roadmap follows Chinese release schedules, which means UK or US support and contract terms are still maturing.
• •API quotas favour heavy spenders API pricing per second of generated video is competitive at scale, but light API users may find OpenAI Sora and Veo simpler to integrate at low volume.
• •Mid-tier subscriptions hit credit walls fast 1080p video generation burns credits quickly on busy days, so any team running daily output should price for Ultra not Standard.
