Switch in one line

Both models live behind Railwail's OpenAI-compatible endpoint. Replace the model string and you are done.

JavaScript / TypeScript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://railwail.com/v1",
});

// Before β€” using Octo Base
let r = await client.chat.completions.create({
  model: "rail-berkeley/octo-base-1.5",
  messages: [{ role: "user", content: "Hello" }],
});

// After β€” switched to Gemini Robotics (2025)
r = await client.chat.completions.create({
  model: "gemini-robotics",
  messages: [{ role: "user", content: "Hello" }],
});
Python
from openai import OpenAI
