Grok 4.1 Thinking

By xAI
New Text Gen 7
Released: November 18, 2025

Overview

Grok 4.1 is xAI’s reasoning model tuned for stronger analysis and coding with faster, more direct answers. It supports long context, tool and function calling, streaming, and clean JSON, making it a solid default for assistants, RAG, and agent workflows.

Description

Grok 4.1 focuses on practical accuracy without heavy latency. It follows instructions closely, keeps multi-document prompts coherent, and handles software tasks from generation to debugging with clear explanations. The model integrates with retrieval so answers can be grounded in your data, returns schema-true JSON for automation, and calls tools to search, run code, or query services during a response. Streaming keeps interactions responsive, quantization options help control serving cost, and alignment targets safe, steady behavior for customer-facing apps. Teams typically use Grok 4.1 as the everyday engine for knowledge copilots, analytics explainers, and repo-aware code helpers, routing only the hardest problems to a heavier tier when extra deliberation is required.
