Adam Perry @ OpenAI 0eb98b4617 Upgrade Python SDK model generation to datamodel-code-generator 0.64.0 (#56272 )

## What changed

- Regenerate protocol models with `datamodel-code-generator==0.64.0`, targeting Python 3.10.
- Preserve discriminator field titles without introducing extra `RootModel` wrappers for literal values or inline unions.
- Keep nullable project and section IDs optional for compatibility with older SDKs, and remove redundant required-nullable field patches.

## Testing

Extend schema annotation coverage to assert that `ReasoningSummary.model_validate("none").root` remains the string `"none"`.

OpenAI Codex Python SDK

Build Python applications that start Codex threads, run turns, stream progress, and control workspace access.

Install

Install the SDK:

pip install openai-codex

Quickstart

The SDK reuses your existing Codex authentication when one is already available:

from openai_codex import Codex

with Codex() as codex:
    thread = codex.thread_start()
    result = thread.run("Explain this repository in three bullets.")
    print(result.final_response)

thread.run(...) returns a TurnResult containing the final response, collected items, and token usage.

Authentication

Existing Codex authentication is reused automatically. To start ChatGPT browser login explicitly:

from openai_codex import Codex

with Codex() as codex:
    login = codex.login_chatgpt()
    print(login.auth_url)
    print(login.wait().success)

For device-code login:

with Codex() as codex:
    login = codex.login_chatgpt_device_code()
    print(login.verification_url, login.user_code)
    login.wait()

For API-key login:

with Codex() as codex:
    codex.login_api_key("sk-...")

Built-In Help

Use Python's standard help(openai_codex), help(Codex), or python -m pydoc openai_codex documentation tools.
