Keyan Zhang 90abcfac02 Add experimental thread prediction protocol types (#49480)
## What changed

Define `thread/prediction/request` with `threadId` and `sourceTurnId`, and `thread/prediction/updated` with a `completed` result containing optional text or a `failed` result.

Update generated JSON schemas, TypeScript types, and Python notification models. Route prediction notifications to their thread in the TUI and ignore them in the chat widget.

The request remains unimplemented and returns a method-not-found error.

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.
