← Back to Blog

Building an AI chatbot doesn't have to cost a fortune. Here's how to build one for just $5/month.

The $500 Problem

Most developers use GPT-4 for chatbots, costing $195-500/month for 10K messages.

The $5 Solution

DeepSeek V4 offers the same quality at $0.91/month for 10K messages.

Step-by-Step Guide

1. Sign up for DeepSeek API
2. Use the OpenAI-compatible endpoint
3. Deploy on Vercel/Netlify (free tier)
4. Total cost: $5/month

Code Example

javascript
const response = await fetch('https://api.deepseek.com/v1/chat/completions', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer your-key'
    },
    body: JSON.stringify({
        model: 'deepseek-chat',
        messages: [{ role: 'user', content: userInput }]
    })
});
