According to CoinMeta, Kuaishou's Keling AI announced that kling 4.0 Flash is now officially open to all users. This version focuses on fast and low-cost video generation, and was initially available only to Black Gold annual card members starting from September 28th. Flash retains features such as text-to-video, image-to-video, and multi-material reference generation, but makes trade-offs in video specifications and control precision. It allows for the generation of videos up to 20 seconds long at 720p resolution per attempt, while the full version supports the generation of videos up to 30 seconds long with higher resolution. Developers can integrate this lightweight model into AI agent through API, MCP, and CLI, for automated and batch video generation. Additionally, a Adobe plugin is provided, enabling creators to directly call the model within Photoshop, Premiere Pro, and After Effects.
