// First turn
const res1 = await client.chat.completions.create({
  model: "deepseek-v4-flash",
  messages,
});
messages.push(res1.choices[0].message);
messages.push({ role: "user", content: "Recommend a good ship." });

// Second turn with history
const res2 = await client.chat.completions.create({
  model: "deepseek-v4-flash",
  messages,
});
console.log(res2.choices[0].message.content);

TypeScript

OpenAI SDK 包含完整的 TypeScript 类型定义：

TypeScript

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.pandaworld.space/v1",
  apiKey: process.env.PANDA_API_KEY!,
});

// Response is fully typed
const response: OpenAI.Chat.Completions.ChatCompletion =
  await client.chat.completions.create({
    model: "deepseek-v4-flash",
    messages: [{ role: "user", content: "Hello!" }],
  });

console.log(response.usage?.total_tokens);
