There's a little typo:

import { ChatAnthropicMessages } from "@langchain/anthropic";

const model = new ChatAnthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
  model: "claude-3-sonnet-20240229",
});
const response = await model.stream(new HumanMessage("Hello world!"));

Should be

import { ChatAnthropicMessages } from "@langchain/anthropic";

const model = new ChatAnthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
  model: "claude-3-sonnet-20240229",
});
const response = await model.stream([new HumanMessage("Hello world!")]);

just missing the array brackets
