OpenAI: GPT-5.1

400K

GPT-5.1 is the latest frontier-grade model in the GPT-5 series, offering stronger general-purpose reasoning, improved instruction adherence, and a more natural conversational style compared to GPT-5. It uses adaptive reasoning to allocate computation dynamically, responding quickly to simple queries while spending more depth on complex tasks. The model produces clearer, more grounded explanations with reduced jargon, making it easier to follow even on technical or multi-step problems. Built for broad task coverage, GPT-5.1 delivers consistent gains across math, coding, and structured analysis workloads, with more coherent long-form answers and improved tool-use reliability. It also features refined conversational alignment, enabling warmer, more intuitive responses without compromising precision. GPT-5.1 serves as the primary full-capability successor to GPT-5

API 사용법

Python (OpenAI SDK 호환)

from openai import OpenAI

client = OpenAI(
    api_key="your-dream-api-key",
    base_url="https://api.invoicedream.co.kr/v1"
)

response = client.chat.completions.create(
    model="openai/gpt-5.1",

Node.js / TypeScript

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'your-dream-api-key',
  baseURL: 'https://api.invoicedream.co.kr/v1'
});

const response = await client.chat.completions.create({
  model: 'openai/gpt-5.1',
  messages: [{ role: 'user', content: '안녕하세요' }]
});

console.log(response.choices[0].message.content);

cURL

curl https://api.invoicedream.co.kr/v1/chat/completions \
  -H "Authorization: Bearer your-dream-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-5.1",
    "messages": [{"role": "user", "content": "안녕하세요"}]
  }'

💡 Tip: OpenAI SDK를 그대로 사용할 수 있습니다.base_url만 변경하면 됩니다!
