### Create a Session with codex harness via OpenAI SDK

Source: https://minimax-ai.github.io/OpenAgentCore

Creates a Session with the OpenAI SDK, using the codex harness and the responses model protocol. Configure OPENAI_BASE_URL, MODEL, BASE_URL, and API_KEY beforehand. The session input is "Fix the failing test and explain the change.".

```python
```
from openai import OpenAI

client = OpenAI()  # OPENAI_BASE_URL → your Core

session = client.beta.agents.sessions.create(
    environment={"type": "openai_hosted"},
    input="Fix the failing test and explain the change.",
    extra_body={
        "agent": {"model": MODEL, "x_agents_core": {"harness": "codex"}},
        "x_agents_core": {"model_provider": {
            "protocol": "responses",
            "base_url": BASE_URL, "api_key": API_KEY,
        }},
    },
)
