Grok Imagine Review — xAI's Aurora Model Hits #1 on Every Video Leaderboard

Grok Imagine (powered by Aurora) launched October 2025 with native audio from day one — and by February 2026 had claimed #1 on Artificial Analysis for both text-to-video and image-to-video (1,336 Elo). API pricing at $4.20/min with audio undercuts Veo 3.1 by 3× and Sora by 7×. No official MCP server. Spicy Mode deepfake controversy drew UK, EU, and US regulatory investigations. Rating 4/5.
