OpenAI API

ELI5 — The Vibe Check

The OpenAI API is the gateway to GPT models that kicked off the AI revolution. Send text in, get smart text back. It's the API that launched a thousand startups and made every developer think 'what if I just add AI to this?' The ChatGPT backend, available to anyone with an API key and a credit card.

Real Talk

OpenAI's REST API providing access to GPT-4, GPT-4o, DALL-E, Whisper, and embedding models. It supports chat completions, function calling, JSON mode, vision, streaming, and fine-tuning. The de facto standard API format that many competitors have adopted for compatibility.

Show Me The Code

import OpenAI from 'openai';

const client = new OpenAI();
const completion = await client.chat.completions.create({
  model: 'gpt-4o',
  messages: [{ role: 'user', content: 'Explain recursion simply.' }]
});
