Grok ships brand-creation feature, but WSJ reports xAI losing ground; Anthropic-SpaceX deal emerges

xAI's Grok rolled out a brand-creation feature that generates a full brand identity — logos, product teasers, social content, names, messaging, and consistent audio identity — from a text prompt in seconds, leveraging the Aurora image/video model, AI naming, and custom voice cloning. Separately, WSJ reports Grok is losing competitive ground, with rivals out-shipping xAI on capability and enterprise traction — and an Anthropic-SpaceX AI deal emerging despite Musk's xAI ownership.
