Grok 4.6 model is a frontier LLM built by xAI and offered inside AI coding tools such as Cursor. The variant tracked on BuildersgateGG, cursor-grok-4.6-xhigh-fast, runs this model at xhigh reasoning effort in the faster-response fast tier.
Grok 4.6 is built for complex coding work, long-running agentic tasks, and workflows that chain many tool calls together. The xhigh setting lets the model reason for longer before answering, which improves accuracy on hard problems, while the fast tier keeps that reasoning quality while targeting latency-sensitive use.
On BuildersgateGG this model is documented as a reference point for choosing between reasoning depth and response speed when picking a model for a coding agent or AI coding tool.
It's a frontier LLM built by xAI, designed for complex coding and long-running agentic work, available inside AI coding tools like Cursor.
It's a reasoning effort setting that lets the model spend more time reasoning before answering, improving accuracy on hard problems at the cost of response time.
The fast tier is a variant designed to respond more quickly for latency-sensitive use cases.
