🤖 xAI makes Grok 4 free for all users worldwide 🤖
Xai introduces automatic routing system with expanded usage

xAI has launched Grok 4 as a free service for all users globally, marking a significant shift in AI accessibility. The platform features Auto mode that intelligently routes complex queries to Grok 4, while Expert mode allows users to manually select the advanced model.

For a limited time, xAI is rolling out generous usage limits to encourage exploration of Grok 4's full capabilities.

The move comes as xAI prepares its V7 foundation model, which finished pre-training last week and represents the first natively multimodal system that processes video and audio bitstreams directly without transcription. This breakthrough enables understanding of tonal nuances and mood that traditional text-based systems miss.

🚀Google and NASA test AI for medical care in space 🚀
Crew Medical Officer Digital Assistant could support Mars missions

Google and NASA have collaborated on an innovative proof-of-concept for an automated Clinical Decision Support System called the "Crew Medical Officer Digital Assistant" (CMO-DA). The AI system is designed to assist astronauts with medical help during extended space missions when crews are not in direct contact with Earth-based medical experts.

Trained on spaceflight literature, the system uses cutting-edge natural language processing and machine learning to provide real-time analyses of crew health and performance. Initial trials using the Objective Structured Clinical Examination framework showed promise for reliable diagnoses based on reported symptoms. The tool could benefit both space exploration and remote medical care on Earth.

🧠 Alibaba's Qwen3 models achieve 1M context windows 🧠
It can processes 1,500 pages simultaneously with 3x speed

Alibaba's Qwen3 AI models now support context windows of up to 1 million tokens, equivalent to analyzing approximately 1,200-1,500 pages of text simultaneously. The models are open-source and deliver 3x faster processing speeds than previous versions, putting pressure on rivals with smaller context windows.

The Qwen3-Coder variant enables developers to load entire codebases into the model's working memory for comprehensive analysis.
