Checklist

• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

The current documentation on LangChain(Link: https://js.langchain.com/v0.2/docs/tutorials/chatbot#quickstart) for initializing the ChatOpenAI instance contains an error in the syntax. The provided example uses: const model = new ChatOpenAI(model="gpt-3.5-turbo");, which leads to a ReferenceError. Instead, it should be using an object to pass the configuration parameter, like this: const model = new ChatOpenAI({ model: "gpt-3.5-turbo" });.

Idea or request for content:

To improve the documentation, I suggest updating the example to use the correct syntax: const model = new ChatOpenAI({ model: "gpt-3.5-turbo" });

Hey @enodi! 👋 I'm here to help you with bugs, questions, and becoming a contributor. If you need anything, just let me know!

The correct initialization syntax for the ChatOpenAI instance should indeed use an object to pass the configuration parameter. The example should be updated from:

const model = new ChatOpenAI(model="gpt-3.5-turbo");

to:

const model = new ChatOpenAI({ model: "gpt-3.5-turbo" });

This change will prevent a ReferenceError and ensure the correct initialization of the ChatOpenAI instance ^[1][2].
