Grok Imagine Video 1.5 Lite

[Core Function] Grok Imagine Video 1.5 Lite generates a short video with native audio from a text prompt. [Strengths] It produces lip-synced speech at the lowest price in the Grok Imagine video family, with controllable duration, aspect ratio, and resolution. [Best For] Highly recommended for: simple social clips, animated concepts, and text-only drafts that do not need reference images or pinned frames. [Limitations] Do NOT use this model when a starting image is provided, or for reference images, voice references, first or last frames, keyframes, video editing, or video extension. Duration is 1-15 seconds and resolution is 480p, 720p, or 1080p. 1080p is upscaled from 720p, not native 1080p. [Routing] Use this model for text-only video on the Lite backbone. If the user provides one starting image, use Grok Imagine Video 1.5 Lite I2V. If the user needs reference images, voices, pinned frames, or native 1080p, use the full Grok Imagine Video 1.5 models.
