Example Usage with the Responses API

Python

from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY")
resp = client.chat.completions.create(
    model="gpt-5",
    messages=[{"role":"user","content":"Generate a responsive Pomodoro timer UI in HTML/CSS/JS."}]
)
print(resp.choices[0].message["content"])

Node.js (REST API)

const res = await fetch("https://api.openai.com/v1/chat/completions", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${API_KEY}`,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    model: "gpt-5-mini",
    messages: [{ "role": "user", "content": "Explain blockchain for beginners." }]
  })
});

const data = await res.json();
console.log(data.choices[0].message.content);

Curl

curl https://api.openai.com/v1/chat/completions \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-5-nano","messages":[{"role":"user","content":"Summarize AI ethics in 
3 lines."}]}'

Why GPT-5 Matters

• Unmatched Versatility: Ideal for developers, analysts, and enterprise users working with code, documents, and tools.
• Cost & Performance Efficiency: Mini and Nano variants unlock flexibility for fast, scalable production without breaking the bank.
• Safer Outputs: Hallucination rates significantly lower; better at partial answers than blunt refusal.
• Enterprise Integration: Available via API, ChatGPT tiers (including free), and Microsoft Copilot Studio for enterprise agents.
