AI video generator

An AI video generator is software that takes a text prompt — or an image, or both — and produces a video clip by sampling from a trained AI model. The model has been trained on large amounts of video and image data, and it generates new frames that try to match the prompt. Modern AI video generators include Sora 2 (OpenAI), Google Veo 3.1, Kling 3.0, Hailuo, and 15+ others, most of which are available in VIBE on iPhone, Android, and the web. Generation times range from about 10 seconds (fast models like LTX 2 and Veo 3.1 Fast) to several minutes (flagship-tier models like Sora 2 Pro). Output is typically a short clip — 5 to 30 seconds — at resolutions up to 4K. AI video generators differ in what they're good at: photorealism, cinematic feel, motion fluency, stylized aesthetics, audio generation. The smart move in 2026 is to use several models in one app — like VIBE — rather than commit to a single tool.
