🎨 Kling 4.0 Open to All: 30 Seconds, Stereo Sound, MCP

Kling AI has opened full access to Kling 4.0: videos up to 30 seconds per pass (previously 15), up to 10 keyframes for the timeline, and up to 15 combined references — 10 images and 5 videos totaling up to 30 seconds, with 7 characters. Sound is now stereo, and Portuguese, German, French, and Hindi have been added. The model works via MCP and CLI using account credits; HDR export and API are currently only announcements.

🌍 MCP connects Kling to AI agents like Claude, while CLI connects it to terminal automation: video generation becomes a backend for scripts, agents, and pipelines for studios and developers.

👤 Kling 4.0 is already available on kling.ai: clips up to 30 seconds, 10 keyframes, stereo sound. Developers can connect the model to agents and scripts via MCP or CLI, as there is no official API yet.
