X, the social network owned by Elon Musk, has introduced Grok Imagine, a generative-AI feature that converts text prompts or still images into video, expanding the capabilities of the platform’s in-house chatbot Grok. The tool can produce clips of up to six minutes, add audio tracks and includes a “spicy” mode for more suggestive content. Access is currently limited to premium subscribers who join a wait-list following a closed beta, with the company planning a broader rollout over time. By adding AI-generated video, X moves into a field already occupied by OpenAI’s Sora and Google’s Veo as social platforms race to embed creative tools that keep users on their sites. The debut coincides with a burst of third-party “agentic” AI releases on 16 August, including the open-source memory framework memU, underscoring intensifying competition to build AI companions that remember user preferences and automate everyday tasks.
