Switch Between Both Models With One API Key

Point the official OpenAI SDK, Cursor, or Claude Code at https://newtons.dev/api/v1 and swap the model string on demand:

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.NEWTONS_API_KEY,
  baseURL: "https://newtons.dev/api/v1",
});

// Switch between GPT-6 Sol and GPT-5.6 Sol with 1 line:
const response = await client.chat.completions.create({
  model: "gpt-6-sol", // or "gpt-5.6-sol"
  messages: [{ role: "user", content: "Compare architecture trade-offs." }],
});
