oci-genai-auth

The OCI GenAI Auth Python library provides OCI request-signing helpers for SDKs that call OCI Generative AI, including the OpenAI and Google Gen AI SDKs.

Installation

pip install oci-genai-auth

oci-genai-auth is designed to work together with the official OpenAI SDK.

Using OCI IAM Auth

Use OCI IAM auth when you want to sign requests with your OCI profile (session/user/resource/instance principal). Recommended if you are building OCI-native production workloads.

import httpx
from openai import OpenAI
from oci_genai_auth import OciSessionAuth

client = OpenAI(
    base_url="https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/openai/v1",
    api_key="not-used",
    http_client=httpx.Client(auth=OciSessionAuth(profile_name="DEFAULT")),
)

Using the Google Gen AI SDK

Install the optional Google SDK dependency:

pip install 'oci-genai-auth[google]'

With an OCI Generative AI API key:

import os
from google import genai

client = genai.Client(
    api_key=os.environ["OCI_GENAI_API_KEY"],
    http_options={
        "base_url": "https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/google"
    },
)

For OCI IAM authentication, pass an OCI-signing httpx client. HttpxOciAuth removes Google SDK API-key headers and query parameters before signing the request.

import httpx
from google import genai
from oci_genai_auth import OciSessionAuth

client = genai.Client(
    api_key="not-used",
    http_options={
        "base_url": "https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/google",
        "httpx_client": httpx.Client(auth=OciSessionAuth(profile_name="DEFAULT")),
    },
)

Using API Key Auth

Use OCI Generative AI API Keys if you want a long-lived API key style auth. Recommended if you are migrating from other OpenAI-compatible API providers.

To create the OCI Generative AI API Keys, follow this guide.

You don't need to install oci-genai-auth if you use API key auth.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/openai/v1",
    api_key=os.getenv("OCI_GENAI_API_KEY"),
)

Using OCI Enterprise AI Agents APIs

OCI Enterprise AI Agents provides a unified API for interacting with models and agentic capabilities.

• It is compatible with OpenAI's Responses API and the Open Responses Spec, enabling developers to build agents with OpenAI SDK, OpenAI Agents SDK, LangChain, LangGraph, AI SDK, CrewAI, and more.
• It offers a uniform interface, auth, billing to access multiple model providers including OpenAI, Gemini, xAI, and GPT-OSS models hosted in OCI and your Dedicated AI Cluster.
• It provides built-in agentic primitives such as agent loop, reasoning, short-term memory, long-term memory, web search, file search, image generation, code execution, and more.

In addition to the compatible endpoint to Responses API, OCI Enterprise AI Agents also offers compatible endpoints to Files API, Vector Stores API, and Containers API.

Explore examples to get started.

Note: OpenAI commercial models and image generation are only available to Oracle internal teams at this moment.

import httpx
from openai import OpenAI
from oci_genai_auth import OciSessionAuth

client = OpenAI(
    base_url="https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/openai/v1",
    api_key="not-used",
    project="ocid1.generativeaiproject.oc1.us-chicago-1.aaaaaaaaexample",
    http_client=httpx.Client(auth=OciSessionAuth(profile_name="DEFAULT")),
)

Examples

Demo code and instructions on how to run them can be found in the examples folder.

Install the example dependency with:

pip install -e '.[examples]'
