Capabilities, design details, and architectural traits
Grok 4.6 - Flagship Code and Agentic Model with Configurable Reasoning
Grok 4.6 is xAI's flagship model for code and general-purpose tasks, defined by three stated pillars: agentic tool calling, minimal hallucinations, and configurable reasoning.
| Trait | Detail |
|---|---|
| Configurable reasoning | Reasoning depth adjustable via reasoning_effort parameter |
| Context window | 500,000 tokens |
| Minimal hallucinations | Explicit design goal stated in model documentation |
Post-Training Over Scale
Grok 4.6 reuses the same V9 foundation as its predecessor Grok 4.5, with capability gains delivered through improved supervised fine-tuning and reinforcement learning rather than increased parameter scale. The stated goal is matching or exceeding competing frontier models while preserving the inference speed and token efficiency of Grok 4.5. Supplemental training incorporates SpaceX engineering data, excluding ITAR-restricted material.
