1. pip install langchain-openai

Configure LIBRA

from langchain_openai import ChatOpenAI
llm = ChatOpenAI(model="libra/smart", base_url="https://<your-host>/v1", api_key="libra_sk_...")
print(llm.invoke("Siapa kamu?").content)

Quick start (up and running in 5 minutes)

1. Install, paste the snippet, run it.
2. Open Usage in the console: the call is there with its IDR cost.

FAQ

• 404 / timeout? The base URL is missing /v1 or has an extra /chat/completions. Use exactly https://<your-host>/v1.
• Model not found? Model ids are case-sensitive and must match the console Models page, e.g. libra/smart or asix-deepseek-v4/deepseek-v4-flash.
• 401? The key is wrong, disabled or expired. 402? Your organization balance is Rp 0; see Credits.
• 403 model_not_allowed? The key's guardrails block that model. Ask your workspace Admin or pick another model.
