Grok Imagine Video 1.5 Lite I2V

[Core Function] Grok Imagine Video 1.5 Lite I2V animates a single starting image into a video with native audio. [Strengths] It uses the input image as the first frame, keeps the output aspect ratio aligned with that image, and adds lip-synced speech. [Best For] Highly recommended for: animating a photo or illustration into a short clip when the Lite backbone is enough. [Limitations] Do NOT use this model for text-only generation, reference images, voice references, pinned frames, video editing, or video extension. It requires one starting image. Duration is 1-15 seconds and resolution is 480p, 720p, or 1080p. 1080p is upscaled from 720p, not native 1080p. The output aspect ratio follows the input image. [Routing] Use this model when the user provides one starting image and wants the Lite backbone. For text-only video, use Grok Imagine Video 1.5 Lite. If the user needs reference images, voices, pinned frames, or native 1080p, use the full Grok Imagine Video 1.5 models.
