Grok posted an update to its Imagine Video 1.5 model. The post states that the model now includes text-to-video generation plus image and voice reference options. It also enables native 1080p output. Elon Musk quoted the announcement. Separate posts from accounts including SpaceXAI and Zhiting Hu repeated the same details about the added capabilities. The original release of version 1.5 occurred last month with prior gains in motion and sound. The new post shows sample video output. No independent confirmation of performance appears in the packet.
