Grok Model

The grok function configures Grok as your model provider.

import { createAgent, grok } from "@inngest/agent-kit";

const agent = createAgent({
  name: "Code writer",
  system: "You are an expert TypeScript programmer.",
  model: grok({ model: "grok-4-latest" }),
});

Configuration

The grok function accepts a model name string or a configuration object:

const agent = createAgent({
  model: grok({
    model: "grok-4-latest",
    apiKey: process.env.XAI_API_KEY,
    baseUrl: "https://api.x.ai/v1",
    defaultParameters: { temperature: 0.5 },
  }),
});
