Musk shared a post from Grok Imagine, highlighting that within just ten days, the rendering time for a 6-second video has seen remarkable improvements. Initially taking 60 seconds, the duration swiftly decreased to 45 seconds, then 30 seconds, and now stands at an impressive 15 seconds. This week, it is projected to be further refined, potentially reaching a rendering time of just 12 seconds, all without compromising on the visual quality of the video.
