You can set the openai API environment variable "OPENAI_API_BASE".

Just pass this parameter openai_api_base see https://github.com/hwchase17/langchain/blob/master/langchain/llms/openai.py#L148

ChatOpenAI(
        temperature=temperature,
        max_tokens=2000,
        model_name=api_key.model,
        openai_api_key=api_key.api_key,
        openai_api_base=api_key.api_base,
)

The gpt4-pdf-chatbot-langchain project is an application of langchian's typescript version. I have not found the interface to modify the host, i.e., the attribute openai_api_base.

Hi, @liuyang77886! I'm Dosu, and I'm here to help the LangChain team manage our backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, you were requesting guidance on how to modify the default API request address in the langchain package to a proxy address for restricted local network access to api.openai.com. Users liaokongVFX and FlowerWrong have provided solutions by setting the OPENAI_API_BASE environment variable and passing the openai_api_base parameter respectively. User zerrymore11 mentioned that they couldn't find the interface to modify the host.

I'm happy to inform you that this issue has been resolved. The provided solutions by liaokongVFX and FlowerWrong should allow you to modify the default API request address. You can either set the OPENAI_API_BASE environment variable or pass the openai_api_base parameter. These solutions should address your concern about modifying the host.

Before we close this issue, could you please confirm if this issue is still relevant to the latest version of the LangChain repository? If it is, please let us know by commenting on this issue. Otherwise, feel free to close the issue yourself. If we don't hear from you within 7 days, the issue will be automatically closed.

Thank you for your understanding and contribution to the LangChain project!

Best regards, Dosu

The gpt4-pdf-chatbot-langchain project is an application of langchian's typescript version. I have not found the interface to modify the host, i.e., the attribute openai_api_base.

with langchainjs,It can be :

const model = new ChatOpenAI({ configuration: { baseURL:"YOUR PROXY URL "}, apiKey: "YOUR API KEY", model:"XXX" });
