Migrate from the Vercel AI SDK OpenAI provider to TokenRex

Steps

• Create a TokenRex API key.
• Create an OpenAI provider with a custom baseURL.
• Use any enabled model ID.

What to check after switching

• Run your existing test prompts and compare replies.
• Check the usage field in responses to confirm token counts and costs.
• Short model IDs are used on TokenRex, for example gpt-6-sol rather than openai/gpt-6-sol.

Example

import { createOpenAI } from "@ai-sdk/openai";
import { generateText } from "ai";

const tokenrex = createOpenAI({ apiKey: process.env.TOKENREX_API_KEY, baseURL: "https://tokenrex.ai/api/public" });
const { text } = await generateText({ model: tokenrex.chat("gpt-6-astra"), prompt: "Hello" });

Questions

Can I switch back?

Yes. Nothing is locked in: change the base URL and key back and your code keeps working.
