从 OpenAI 兼容端点开始

NextModel 是一个 AI API 成本治理网关，尽量保持你熟悉的调用方式。将 SDK base URL 设置为 https://api.nextmodel.app/v1，使用 NextModel API Key，并从模型目录选择模型 ID。

Python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.nextmodel.app/v1"
)

resp = client.chat.completions.create(
    model="doubao-seed-2-0-mini",
    messages=[{"role": "user", "content": "Hello from NextModel"}]
)

print(resp.choices[0].message.content)
Node
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.NEXTMODEL_API_KEY,
  baseURL: "https://api.nextmodel.app/v1",
});

const response = await client.chat.completions.create({
  model: "doubao-seed-2-0-mini",
  messages: [{ role: "user", content: "Hello from NextModel" }],
});

console.log(response.choices[0].message.content);
curl
curl https://api.nextmodel.app/v1/chat/completions \
  -H "Authorization: Bearer $NEXTMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seed-2-0-mini",
    "messages": [{"role": "user", "content": "Hello from NextModel"}]
  }'

从现有 OpenAI 项目迁移时要改什么？

大多数迁移只需要调整三个字段：base URL、API Key 和模型名。应用可以继续保留同样的 chat completions 请求结构，同时开始比较模型价格、能力和提供方来源。
