After Gemini 3 and ChatGPT 5.1, @xai launched Grok 4.1. I played around a bit with it today, here is what I found: You get live situational awareness and trend radar while other models are still chewing on yesterday data. Strong at live research social web analysis and sharp executive briefings... exactly what I need for my ai-powered family office. The tone is direct humorous and human so it feels more like a sharp cofounder than a corporate chatbot. Some facts based on xAI's reporting: -> Grok 4.1 is the first model on X that is actually built for live research -> Hallucination rate cut from above 12 percent to about 4.2 percent -> LMArena Elo 1483 in thinking mode -> Almost 65 percent user preference in blind tests Native live search with direct access to web and X Well done @elonmusk and team!(Dr. Julian Hosp)
