Anthropic Model

The anthropic function configures Anthropic’s Claude as your model provider.

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

const agent = createAgent({
  name: "Code writer",
  system: "You are an expert TypeScript programmer.",
  model: anthropic({
    model: "claude-3-opus",
    // Note: max_tokens is required for Anthropic models
    defaultParameters: { max_tokens: 4096 },
  }),
});
