LangChain (JS) with idapt

ChatOpenAI against idapt's compatible API: one configuration block, 200+ models.

  1. 1

    Install

    bash
    npm i @langchain/openai
  2. 2

    Point it at idapt

    ts
    import { ChatOpenAI } from "@langchain/openai";

const model = new ChatOpenAI({
  model: "openai/gpt-6-astra",
  apiKey: process.env.IDAPT_API_KEY,
  configuration: { baseURL: "https://idapt.app/api/openai/v1" },
});
  3. 3

    Going further

    ts
    const withTools = model.bindTools([myTool]);
const reply = await withTools.invoke("What is 23 * 17? Use the calculator.");

    Tool calling passes through for every tool-capable catalog model.
