Ruby langchainrb gem and custom configuration for the model setup

题意：Ruby 的 langchainrb gem 以及针对模型设置的自定义配置

问题背景：

I am working in a prototype using the gem langchainrb. I am using the module assistant module to implemente a basic RAG architecture.

我正在使用 langchainrb 这个 gem 来开发一个原型。我利用其中的 assistant 模块来实现一个基本的 RAG（Retrieval-Augmented Generation，检索增强生成）架构。

Everything works, and now I would like to customize the model configuration.

一切运行正常，现在我想自定义模型的配置。

In the documenation there is no clear way of setting up the Model. In my case, I would like to use OpenAi and use:

在文档中，没有明确的方法来设置模型。在我的情况下，我想使用 OpenAI 并使用以下配置：

temperature: 0.1
Model: gpt-4o

In the README, there is a mention about using llm_options.

在 README 文件中，提到了使用 llm_options。

If I go to the OpenAI Module documentation:

如果我去查看 OpenAI 模块的文档：

Class: Langchain::LLM::OpenAI — Documentation for langchainrb (0.13.4)

It says I have to check here: 它说我要查看这里：

But there is not any mention of temperature, for example. Also, in the example in the Langchain::LLM::OpenAI documentation, the options are totally different.

但是在文档中并没有提到例如“温度”这样的设置。此外，在 Langchain::LLM::OpenAI 的文档示例中，给出的选项是完全不同的。

# ruby-openai options:

CONFIG_KEYS = %i[
  api_type
  api_version
  access_token
  log_errors
  organization_id
  uri_base
  request_timeout
  extra_headers
].freeze

# Example in Class: Langchain::LLM::OpenAI documentation: 

{
  n: 1,
  temperature: 0.0,
  chat_completion_model_name: "gpt-3.5-turbo",
  embeddings_model_name: "text-embedding-3-small"
}.freeze

问题解决：

I have a conflict between llm_options and default_options. I thought it was the same with different priorities.

我在 llm_options 和 default_options 之间遇到了冲突。我原本以为它们只是优先级不同的相同设置。

For the needs expressed in the question I have to use the default_options as in here:

针对问题中表达的需求，我必须按照这里的示例来使用 default_options：

llm =
  Langchain::LLM::OpenAI.new(
    api_key: <OPENAI_KEY>,
    default_options: {
      temperature: 0.0,
      chat_completion_model_name: "gpt-4o"
    }
  )
