xAI Grok in a visual AI workflow

Run xAI's Grok models in NodeTool chat and agent nodes — capable reasoning with tool use, called with your own xAI key.

ReasoningToolsChatx.ai

xAI's Grok models are general-purpose chat and reasoning models with tool-use support. In NodeTool, Grok slots into chat nodes, agents, and any LLM step in a workflow.

Grok is bring-your-own-key: set `XAI_API_KEY` and NodeTool calls xAI directly at list price. Swap Grok for another model on the node whenever you want to compare.

Calls go straight to xAI Grok with your key at their list price — NodeTool never proxies or marks up the request.
