Simple Response from GPT-4 | ChatOpenAI.modelName="gpt-4" but responses are of "gpt-3"

[yaronl3v]

Hello,

Trying to make a call to GPT-4, basically, all is working well except the response I get is actually from GPT-3. Any idea what I am doing wrong?

Q: Which GPT is this?
A: As an AI developed by OpenAI, I am based on the GPT-3 model

npm install -S langchain

import { ChatOpenAI } from "langchain/chat_models/openai";
import { HumanMessage } from "langchain/schema";

async function main () {
    const chat = new ChatOpenAI({
        modelName: "gpt-4", 
        temperature: 0,
        openAIApiKey: "sk-****", // In Node.js defaults to process.env.OPENAI_API_KEY
        maxTokens: 225,
        //streaming: true
    });

    const response = await chat.call([
        new HumanMessage(
            "Which gpt is this?",
        ),
    ]);
    console.log(response);
    //Response:
    //'As an AI developed by OpenAI, I am based on the GPT-3 model.
}

main ();

@yaronl3v I know it's confusing, but this is a standard response from GPT-4. The best way to sanity check if the GPT-4 is actually getting called is to look at your Open AI account usage page

It's confusing because the chat-gpt web app does return that this is gpt-4 while the API endpoint, does not (tested). Tres bizarre, thx!
