Kling AI is a generative video platform from Kuaishou, the Beijing-based company behind the Kuaishou short-video app. A user writes a prompt or supplies a reference image, and Kling generates a short video clip, with later versions adding synchronized audio (dialogue, sound effects, and ambient sound), motion and camera control, lip sync, virtual try-on, and AI digital humans. It launched as a beta in June 2024 inside Kuaishou's KuaiYing editing app, and the model line has iterated quickly through 2.5 Turbo (September 2025) and 3.0 (February 2026). Kling is a consumer and creator generation tool, not an agent: a human prompts a clip, reviews it, and iterates. It is available through a web app (kling.ai internationally, klingai.com in China), a developer API, and a credit-based subscription. The autonomy level is assistant: it produces media on request and does not plan or take multi-step actions on its own.

What it can do

  • Generate video from a text prompt

    Assistant

    Produces short video clips from natural-language prompts. Kuaishou describes its 2.5 Turbo model as offering improved prompt comprehension for complex multi-step instructions, character interactions, and scene transitions.

  • Image-to-video generation

    Assistant

    Animates a supplied reference image into a moving clip, with the 2.5 Turbo model reportedly improving motion dynamics, camera movement, and real-world physics simulation.

  • Synchronized audio generation

    Assistant

    Kuaishou says its Video 2.6 model generates audio and visuals simultaneously, producing voiceovers, dialogue, sound effects, and ambient atmosphere alongside the video rather than as a separate step.

  • Motion control, lip sync, and digital humans

    Assistant

    Adds features such as motion brush controls, lip sync, virtual try-on, and AI digital humans on top of base generation. Lip sync and motion brush were reportedly introduced with the 1.5 model in 2024.

  • Programmatic generation via API

    Assistant

    Exposes Kling's generation models to developers through a paid API that uses prepaid resource packages, separate from the consumer subscription credits.

Strengths

  • +Strong generative video quality with synchronized audio in recent models (2.6)
  • +Broad feature set: image-to-video, lip sync, motion control, virtual try-on, digital humans, and a developer API
  • +Free tier plus credit-based subscriptions, with rapid model iteration through 2.5 Turbo and 3.0

Limitations

  • −Credit-based generation: high-quality or longer video consumes credits quickly and there is no unlimited plan
  • −A consumer and creator generation tool, not an autonomous agent: a human prompts and curates every clip
  • −API access is billed separately from web subscriptions; credits do not transfer between the two

Overview

Kling AI is a generative video platform from Kuaishou, the Beijing-based company behind the Kuaishou short-video app. A user writes a prompt or supplies a reference image and Kling generates a short video clip. It launched as a beta in June 2024 inside Kuaishou's KuaiYing editing app, and the model line has iterated quickly through 2.5 Turbo (September 2025) and 3.0 (February 2026).

What it does

Kling generates video from text prompts and from reference images (image-to-video). Recent models add synchronized audio: Kuaishou describes its Video 2.6 model as generating audio and visuals simultaneously, including voiceovers, dialogue, sound effects, and ambient atmosphere. On top of base generation it offers motion control (including a motion brush), lip sync, virtual try-on, and AI digital humans. Generation runs on request under direct human control: you prompt, review, and iterate, which is why its autonomy is assistant, not agent.

Integrations & setup

Kling is available through a web app (kling.ai internationally, klingai.com in China), inside Kuaishou's KuaiYing editing app, and via a developer API. It runs on Kuaishou's proprietary models. The API uses prepaid resource packages and is billed separately from consumer subscriptions, with credits not transferring between the two systems.

Pricing

Freemium with credit-based generation. A free tier grants a daily allotment of credits (reported as 66 daily credits expiring after 24 hours). Paid plans run roughly Standard (around $10/mo, about $6.60/mo billed annually), Pro (around $37/mo), Premier (around $92/mo), and Ultra (around $180/mo); credits are consumed per second of generated video, with rates varying by resolution and audio. Developer API pricing uses separate prepaid resource packages (reported entry trial around $9.80). Specific figures here are drawn from third-party pricing guides.

Traction

Kuaishou reports rapid commercial growth for Kling. Per the company's investor-relations releases, Kling's annualized revenue run rate reached about USD240 million in December 2025, and Q1 2026 revenue exceeded RMB650 million (reported as more than 300% year-over-year growth). Secondary reporting cites figures such as roughly 60 million creators and 600 million videos generated as of December 2025; these third-party and self-reported numbers should be treated as approximate.

Best for / not for

Best for creators, marketers, and ecommerce teams who want realistic short-form AI video with synchronized audio, plus extras like lip sync, virtual try-on, and digital humans. Less suited to anyone needing predictable per-clip cost (credits deplete fast on high-quality output) or a hands-off, autonomous workflow.

Alternatives

Runway offers generative video plus editing and node-based pipelines; OpenAI's Sora was a competing text-to-video model (now being wound down); HeyGen and Synthesia focus on avatar and presenter video.

Is Kling AI an AI agent?+

No. Kling AI is a text- and image-to-video generation model. A human writes the prompt and iterates on the output; it does not plan or take multi-step actions on its own, so it sits at the assistant level of autonomy.

Is Kling AI free?+

There is a free tier that grants a daily allotment of credits (reported as 66 daily credits that expire after 24 hours). Paid plans (Standard, Pro, Premier, Ultra) start around $10/mo and use a credit-based system where credits are consumed per second of generated video.
