Because Newton’s exposes both claude-opus-4-7 and claude-sonnet-5-5 behind the same API key and base URL, engineering teams frequently combine both models in the same workflow:
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 Claude Opus 4.7 and Claude Sonnet 5.5 with 1 line:
const response = await client.chat.completions.create({
model: "claude-opus-4-7", // or "claude-sonnet-5-5"
messages: [{ role: "user", content: "Compare architecture trade-offs." }],
});
