Is there a relation between Langchain::Assistant and the OpenAI Assistants?

[a-chacon]

Firstly, thank you for writing this gem.

I mean, we create an assistant using the langchain assistant and OpenAI as adapter. But when we create an assistant with:

    assistant = Langchain::Assistant.new(
      llm: Langchain::LLM::OpenAI.new(
        api_key: Rails.application.credentials.dig(:openai, :access_token)
      ),
      instructions: set_instructions,
      tools: [
         ....
      ]
    )

I don't get an asssitant_id, neither it is created in OpenAI assistants.

Are the langchain assistants different from the OpenAI assistants? Is there a way to match the Langchain::Assistants to the OpenAI assistants?
