Less plumbing, more shipping

A single, honest gateway for every model — so the boring parts stay boring.

Switch in one line

Keep your OpenAI SDK — just change the base URL and key.

1import OpenAI from "openai";
2
3const client = new OpenAI({
4 baseURL: "https://api.modelplex.ai/v1",
5 apiKey: process.env.MODELPLEX_API_KEY,
6});
7
8await client.chat.completions.create({
9 model: "claude-opus-4-8",
10 messages: [{ role: "user", content: "Hello!" }],
11});

Only the highlighted lines change — the rest of your code stays the same.

Why a gateway, not N integrations

Replace a tangle of integrations with a single endpoint.
