Multi-turn conversations (TypeScript)

For Chat Completions, keep the messages needed for context in your application and send them with the next request. Do not assume the API saves the conversation automatically.

This guide uses the official OpenAI client with TheRouter; it is not a TheRouter-owned SDK. The therouter and @therouter/sdk packages previously named here are not currently published in the public package registries.

npm install openai

import OpenAI from "openai";

const client = new OpenAI({ apiKey: process.env.THEROUTER_API_KEY, baseURL: "https://api.therouter.ai/v1" });
const completion = await client.chat.completions.create({
  model: "openai/gpt-4o-mini",
  messages: [{ role: "user", content: "Hello!" }],
  max_tokens: 32,
});
console.log(completion.choices[0]?.message.content);
