Grok 4.6 extended Grok 4.5 for longer agent runs and more ambitious interactive work. xAI describes a longer supplemental training run with technical data and agentic learning tasks.

xAI reports that Grok 4.6 turns a product idea into a first working application and self-tests its work on longer trajectories. The weights remain proprietary.
