Kling

0:33 Kling is an AI video generator made by Kling AI, the video unit of the Chinese short-video company Kuaishou, and its newest model, Kling 4.0, launched on Oct 15, 2026 with single clips of up to 30 seconds, up to 10 keyframe images to steer them and up to 15 reference files. You can use it at kling.ai or through its API, where Kling 3.0 costs from $0.084 a second at 720p, and it is also sold inside Runway at 118 credits per 5 seconds of 1080p Kling 4.0, Luma and Pika (as of Nov 6, 2026).

Kling's strength is long, stable single shots with complex camera moves; no other model on this page set makes 30 seconds in one take except Seedance 2.5. Its weak spot is independent proof: as of Nov 6, 2026 neither Kling 3.0 nor Kling 4.0 appears on Arena's text-to-video leaderboard, where the best Kling entry, Kling 2.6 Pro, is 31st (Arena). For the highest measured quality, Google's Gemini Omni in Google Flow is first there. Best AI Video Generator compares them.

Quick facts

Kling pricing

Kling sells monthly memberships with credits on kling.ai, but its membership page did not show the consumer plan prices when read on Nov 6, 2026 (prices appear after signing in and vary by region), so they are not listed here. The same page publishes the API prices, billed per second of video:

Source: Kling AI API pricing, read Nov 6, 2026. Kling 4.0 had no published API price on that page. Through resellers, Kling 4.0 costs 118 Runway credits per 5 seconds at 1080p (Runway).

Models

1:20 Kling 4.0 (Oct 15, 2026) focuses on realism, steadier motion in big action scenes and smoother tracking and orbit shots, and "Omni Reference" takes up to 15 reference files and 10 keyframes. Kuaishou announced it on Oct 19, 2026 (Bernama). Luma added it on Oct 23, 2026, and Pika and Runway list it too. In Film Crux's Oct 20, 2026 tutorial, Omni Reference took up to 10 references in one generation, up to five of them video clips, with up to seven subjects in a shot.

Kling 3.0 series (Feb 2026) generates up to 15 seconds and arrived with a Team Plan for up to 15 people working together (Kuaishou Q1 2026 results). Kling 3.0 Omni adds video input and editing, and Kling 3.0 Turbo is the faster, cheaper variant.

Earlier models. Kling 2.6 Pro, Kling 2.5 Turbo, Kling O1 Pro and Kling 2.1 Master all appear on Arena's board, at 31st, 30th, 35th and 42nd (Arena).

Features

Long takes. 30 seconds per generation in Kling 4.0, the longest single clip among the major video models as of Nov 6, 2026, tied with Seedance 2.5.

1:18 Native audio. Kling 3.0 generates sound with the video, billed as a separate tier in the API.

2:33 Edits, text and wide frames. In Film Crux's Oct 20, 2026 tutorial, Kling 4.0 edited an existing clip (a new subject or background, the rest kept), wrote readable text into a scene, such as a sign or a title card, and offered a 21:9 ultrawide ratio; a faster, cheaper Kling 4.0 Flash is also offered.

Motion control and avatars. Motion Control copies movement from a reference video, and Avatar animates a talking character, both priced in the API table above.

Effects. Kling sells template effects; in Q1 2026 Kuaishou said its "Baseball Live" effect took the Kling app to number one on the App Store in 42 countries and regions (Kuaishou).

Business

Kling is one of the few AI video products with public revenue figures. Kuaishou reported Kling revenue of over RMB 650 million in the first quarter of 2026, more than 300% higher than a year earlier, and an annualized run rate of about $500 million in March 2026 (Kuaishou, May 27, 2026). In May 2026 Kuaishou said in a Hong Kong filing that it was assessing a restructuring of Kling's business that could bring in outside investors (Caixin, May 13, 2026).
