xAI has officially launched Grok Imagine Video 1.5 Lite, a low-cost video generation model that ranks 17th in the Artificial Analysis T2V v2.0 arena, surpassing Google's Veo 3.1. With an aggressive pricing strategy, the model costs only $0.14 per second at 1080p resolution—approximately one-third of Veo 3.1—while maintaining a median generation time of 60.5 seconds, securing its position on the quality-speed Pareto frontier.
Cross-verified reports indicate that Video 1.5 Lite is positioned as a 'workhorse' for text-to-video and image-to-video tasks, supporting durations of 1-15 seconds and resolutions up to 1080p. Its optimized architecture delivers near-top-tier performance in multi-scene narratives, lighting/material rendering, and text rendering. The model is now accessible via OpenRouter, lowering integration barriers for developers.
This release signals a shift in the AI video sector from pure quality pursuit to balancing cost-efficiency with scalability. By offering a highly competitive alternative, Grok Imagine Video 1.5 Lite may pressure other leading vendors to reassess their pricing and technical efficiency, accelerating the adoption of generative video in advertising, gaming, and content creation.
