I found a similar unsolved discussion titled "Langchain with Local LLMs as API" that might be relevant to your question. You can view it here ^[1].

For your specific issue, since the Node.js version of LangChain does not have a direct equivalent to the VLLMChatModel available in Python, you might consider creating a custom integration. This could involve setting up a local server that uses the Python VLLMChatModel and communicates with your Node.js application via HTTP requests. Alternatively, you could explore using the OpenAI API compatibility of VLLM to interact with it from Node.js, treating it as you would any other OpenAI model.

i found just use ChatOpenAI like below is fine

const llm = new ChatOpenAI({
    model: "deepseek-ai/deepseek-llm-7b-chat",
    temperature: 0,
    configuration: {
        baseURL: "http://192.168.8.245:18000/v1",
    },
    apiKey: "fake"
});

it return the expect aimsg, but i am not sure is the right way to use.
