Product brief
What Kling 4.0 does.
Kling 4.0 is an AI video model for creators, marketers and studios who need control, not lucky rerolls. Unlike prompt-and-pray generators, you lock the story first: up to 10 keyframes, 15 reference assets and 8,000-token prompts drive 30-second clips in a single pass. Stereo audio and lip sync in 10+ languages are built in. Creative Recreation swaps products or characters in existing videos. Kling 4.0 Flash handles fast, cheaper drafts, and MCP + CLI access plugs it into agent workflows.
