Migrating from OpenAI

The ai& Inference API is wire-compatible with the OpenAI Chat Completions, Responses, and Models APIs. If you have an OpenAI integration already, you can usually migrate by changing the base URL and the API key.

Change two things

Python
Node.js

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aiand.com/v1",
    api_key="sk-your-aiand-api-key",
)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.aiand.com/v1",
  apiKey: "sk-your-aiand-api-key",
});

Everything else — chat.completions.create, streaming, tool calls, structured outputs — works as-is.

Supported endpoints

OpenAI endpoint	ai& path	Notes
`/v1/chat/completions`	Chat Completions	Full parity
`/v1/models`	Models	Returns models your org has access to
`/v1/files`	Files	Same multipart upload shape
`/v1/uploads`	Uploads	Chunked uploads for large files

What’s different

API keys start with sk- like OpenAI’s but are issued by ai& — see Authentication.
Model IDs differ. List them with client.models.list() or see the catalog.
Org scoping — pass X-Org-ID when using JWT auth. API keys carry their org automatically.
