import OpenAI from 'openai';
import * as pc from 'picocolors';

export async function run() {
  const deepseek = new OpenAI({
    baseURL: 'https://api.deepseek.com/v1',
    apiKey: process.env.DEEPSEEK_API_KEY,
  });
  const response = await deepseek.chat.completions.create({
    model: 'deepseek-reasoner',
    messages: [{ role: 'user', content: 'how old is Zhang Zi Yi?' }],
    stream: true,
  });
  let reasoning = '';
  for await (const chunk of response) {
    const reason = (chunk.choices[0].delta as { reasoning_content: string })
      ?.reasoning_content;
    if (reason !== null) {
      reasoning += reason;
      process.stdout.
