Grok update reshapes X feed

This looks like xAI trying to make Grok the control plane for both discovery and creation on X. If that lands, X stops feeling like a social app with AI bolted on and starts feeling like an AI-ranked distribution layer.

• –X already has an open-sourced recommendation stack, so the real shift is probably more Grok-shaped scoring and retrieval, not a total rewrite overnight.
• –Grok Imagine is already a serious multimodal line: xAI ships image generation, image editing, and video/audio workflows via API, so this reads as acceleration, not a debut.
• –The moderation risk is the big drag. Grok image tools have already drawn backlash over deepfakes and paywall changes, and that baggage will color any expansion.
• –For builders, the signal is that xAI wants a fuller stack spanning search, ranking, images, video, and tools, which makes Grok strategically more important than a standalone chatbot.
