# Getting Started
|
|
|
|
This is the fastest path from install to a multi-turn thread using the public SDK surface.
|
|
|
|
The SDK is experimental. Treat the API, bundled runtime strategy, and packaging details as unstable until the first public release.
|
|
|
|
## 1) Install
|
|
|
|
From repo root:
|
|
|
|
```bash
|
|
cd sdk/python
|
|
python -m pip install -e .
|
|
```
|
|
|
|
Requirements:
|
|
|
|
- Python `>=3.10`
|
|
- installed `codex-cli-bin` runtime package, or an explicit `codex_bin` override
|
|
- local Codex auth/session configured
|
|
|
|
## 2) Run your first turn (sync)
|
|
|
|
```python
|
|
from codex_app_server import Codex, TextInput
|
|
|
|
with Codex() as codex:
|
|
print("Server:", codex.metadata.server_name, codex.metadata.server_version)
|
|
|
|
thread = codex.thread_start(model="gpt-5", config={"model_reasoning_effort": "high"})
|
|
result = thread.turn(TextInput("Say hello in one sentence.")).run()
|
|
|
|
print("Thread:", result.thread_id)
|
|
print("Turn:", result.turn_id)
|
|
print("Status:", result.status)
|
|
print("Text:", result.text)
|
|
```
|
|
|
|
What happened:
|
|
|
|
- `Codex()` started and initialized `codex app-server`.
|
|
- `thread_start(...)` created a thread.
|
|
- `turn(...).run()` consumed events until `turn/completed` and returned a `TurnResult`.
|
|
- one client can have only one active `Turn.stream()` / `Turn.run()` consumer at a time in the current experimental build
|
|
|
|
## 3) Continue the same thread (multi-turn)
|
|
|
|
```python
|
|
from codex_app_server import Codex, TextInput
|
|
|
|
with Codex() as codex:
|
|
thread = codex.thread_start(model="gpt-5", config={"model_reasoning_effort": "high"})
|
|
|
|
first = thread.turn(TextInput("Summarize Rust ownership in 2 bullets.")).run()
|
|
second = thread.turn(TextInput("Now explain it to a Python developer.")).run()
|
|
|
|
print("first:", first.text)
|
|
print("second:", second.text)
|
|
```
|
|
|
|
## 4) Async parity
|
|
|
|
```python
|
|
import asyncio
|
|
from codex_app_server import AsyncCodex, TextInput
|
|
|
|
|
|
async def main() -> None:
|
|
async with AsyncCodex() as codex:
|
|
thread = await codex.thread_start(model="gpt-5", config={"model_reasoning_effort": "high"})
|
|
turn = await thread.turn(TextInput("Continue where we left off."))
|
|
result = await turn.run()
|
|
print(result.text)
|
|
|
|
|
|
asyncio.run(main())
|
|
```
|
|
|
|
## 5) Resume an existing thread
|
|
|
|
```python
|
|
from codex_app_server import Codex, TextInput
|
|
|
|
THREAD_ID = "thr_123" # replace with a real id
|
|
|
|
with Codex() as codex:
|
|
thread = codex.thread_resume(THREAD_ID)
|
|
result = thread.turn(TextInput("Continue where we left off.")).run()
|
|
print(result.text)
|
|
```
|
|
|
|
