xAI's Grok Imagine Raises Reference Limit From 7 to 14 for Video Generation
- Grok Imagine can now attach up to 14 references to one video generation, doubling the seven-reference limit introduced with Imagine Video 1.5.
- Users can attach images, voices, character references, and other assets, then call each asset in the prompt with @ tags such as @mara, @loft, and @voice_a.
- The update targets reference-to-video generation, where supplied assets control identity and continuity rather than merely animating a fixed opening image.
- The article says 14 anchors can cover a cast, set, props, and audio identity in a short scene, though conflicting or crowded prompts can still cause references to compete.
- The higher reference limit does not solve long-form continuity across many clips, and reference-driven generation may trade resolution and flexibility for identity control.
