## Why ENT26 plans are billed directly in dollars, so credit estimates and credit-weighted breakdowns do not describe their thread usage. ## What changed - Expose optional `nativeUsageUsdMicros` in app-server `ThreadUsage` responses and generated schemas and SDK types. Missing native usage means unknown, not zero. - Enable ENT26 usage fetching and display native dollar amounts in `/status`, the status line, terminal titles, and the agents overview. Hide credits and omit credit-weighted `/status` breakdowns for these plans. - Use native dollar amounts when tracking post-turn usage settlement for ENT26 plans. ## Testing Add coverage for native usage forwarding, ENT26 billing displays, and settlement polling with stale, missing, or zero dollar amounts.

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
