1. Musk confirms Grok now ingests and reasons over video

xAI. Elon Musk announced on X that Grok can now understand and process video natively, summarizing the change with the line “Grok groks videos,” and followed up minutes later teasing further improvements to image and video generation accuracy. The capability lands ahead of xAI’s expected Grok 5 public beta, which the company has previously described as natively multimodal across text, images, audio, and real-time video in a single model with integrated temporal reasoning. The shift is significant for xAI’s product positioning because video understanding has been one of the visible gaps between Grok and the multimodal stacks at Google, OpenAI, and Anthropic. Source
