| Description | Project Astra is a research prototype from Google DeepMind exploring the capabilities needed for a universal AI assistant that can understand and respond to the world in real time. Built on Gemini models, it processes text, voice, images, and live video to answer questions and complete tasks, drawing on Google apps like Search, Maps, and Lens. It is currently available only to selected testers on Android phones and prototype glasses, and its features are being folded into products such as Gemini Live. | Grok is an AI chatbot developed by xAI, available standalone at grok.com and bundled inside X through Premium plans. It provides sourced research via DeepSearch, pulls live posts from X for current-events questions, and supports extended reasoning, image and video generation, document creation, agentic tool use, and multi-agent reasoning. Developers can access Grok through a usage-based, OpenAI-compatible API with vision, function calling, code execution, and web search capabilities. |
