Grok 4.6 is xAI's smartest model, delivering frontier performance on coding, knowledge work, and STEM tasks. It builds on the Grok 4.5 line with stronger real-world software engineering and reasoning results while keeping the speed and cost efficiency the series is known for.
The model supports a 500K-token context window and accepts text, image, and file inputs. Reasoning is always on, with selectable effort levels so callers can trade latency for depth of thinking. Tool use, structured outputs, and response-format control make it well suited for agentic coding workflows, long-document analysis, and multi-step tasks.
