Kling AI releases Kling 4.0 with stereo audio, multilingual lip‑sync and a faster Flash variant
Kling AI launched Kling 4.0, a major update to its AI video generator that supports single‑pass generations up to 30 seconds, 8,000‑token prompts, and a new "Omni Reference" system accepting up to 15 reference assets (images, videos, elements). The release adds two‑channel stereo audio, improved lip sync across more than ten languages, a Creative Recreation template feature, a redesigned interface, MCP and CLI access for automation, and a lighter Kling 4.0 Flash variant for faster, lower‑cost 720p/20s outputs; 4K HDR and longer (up to two minutes) extensions are listed as coming soon, and API pricing/support were not announced.
