Grok 4.1 is xAI's most advanced AI model, which was first released on November 17, 2025 to customers of xAI’s own conversational chatbot platform.
It’s built on the same large-scale reinforcement learning infrastructure that powered Grok 4, the new model was specifically optimized for style, personality, helpfulness, and alignment.
What makes Grok 4.1 special is its focus on the human side of AI interaction. xAI describes it as "exceptionally capable in creative, emotional, and collaborative interactions" — more perceptive to nuanced intent, more compelling to speak with, and more coherent in personality.
The model comes in two configurations:
- Grok 4.1 (Thinking) — extended reasoning for complex problems. LMArena score of 1,483 Elo.
- Grok 4.1 (Fast) — faster responses LMArena score of 1,483 Elo. For context, it’s a better score than most older generation thinking models, like Gemini 2.5 Pro.
Fun fact: xAI silently rolled out Grok 4.1 over a two-week period to test it, and 64.78% of the time users said they preferred it to the older model in blind evaluations.
