xAI just dropped Grok 4 Fast — an AI model that slashes costs by 98% while keeping near-flagship performance. With a massive 2M token context window, built-in web search, and smarter tool use, it feels less like a chatbot and more like an autonomous agent. Meta also revealed its first display-equipped Ray-Ban glasses bundled with a Neural Band wrist controller, YouTube rolled out a flood of new AI creator tools, and DeepSeek launched a “Safe” variant retrained for strict compliance.
