langchain_openai.Chat[OI]

Native [OI] support

LangChain with a custom [OI] base URL

LangChain's [OI] integration is an [OI] client underneath. Pass base_url (Python) or configuration.baseURL (JS) and the rest of your chain is unchanged.

Base URL

https://uncensoredai.dev/v1

  1. 01

    Python

    Set base_url and api_key on Chat[OI]. Agents, tools and structured output treat it as a normal [OI] model.

    python
    from langchain_openai import Chat[OI]

llm = Chat[OI](
    model="deepseek-v4.1-flash",
    base_url="https://uncensoredai.dev/v1",
    api_key="sk-ua-XXXX-XXXX-XXXX-XXXX",
)
  2. 02

    JavaScript / TypeScript

    With @langchain/openai the endpoint nests under configuration.baseURL.

    typescript
    import { Chat[OI] } from "@langchain/openai";

const llm = new Chat[OI]({
  model: "deepseek-v4.1-flash",
  apiKey: process.env.UNCENSOREDAI_API_KEY,
  configuration: { baseURL: "https://uncensoredai.dev/v1" },
});

FAQ

Which base URL do I pass to Chat[OI]?+

https://uncensoredai.dev/v1 — the SDK appends /chat/completions automatically.

Do LangChain tools and function calling work?+

Yes on models that support the tools array. Use a reasoning tier for reliable tool loops.
