Set up LlamaIndex against idapt's compatible APIs with the steps below. This article and the AI Gateway quickstarts lander render the same shared steps, so they never drift.

LlamaIndex with idapt

OpenAILike against idapt's compatible API for indexes, query engines, and agents.

  1. 1

    Install

    bash
    pip install llama-index llama-index-llms-openai-like
  2. 2

    Point it at idapt

    python
    from llama_index.llms.openai_like import OpenAILike

llm = OpenAILike(
    model="openai/gpt-5.6-luna",
    api_base="https://idapt.app/api/openai/v1",
    api_key=os.environ["IDAPT_API_KEY"],
    is_chat_model=True,
)

    is_chat_model=True routes calls to /chat/completions instead of the legacy completions path.
