## Summary
- Allow thread.turn and turn.steer, including async variants, to accept
RunInput so plain strings work alongside typed input objects.
- Export RunInput and update the SDK artifact generator so regenerated
turn methods keep the same signature and normalization.
- Update docs, examples, notebook cells, and tests to use string
shorthand for text-only turns while keeping typed inputs for multimodal
input.

Python SDK Examples
Each example folder contains runnable versions:
sync.py(public sync surface:Codex)async.py(public async surface:AsyncCodex)
All examples intentionally use only public SDK exports from openai_codex
and openai_codex.types.
Examples use plain strings for text-only turns and typed input objects for multimodal or structured input lists.
Prerequisites
- Python
>=3.10 - Install SDK dependencies for the same Python interpreter you will use to run examples
Recommended setup (from sdk/python):
uv sync
source .venv/bin/activate
When running examples from this repo checkout, the SDK source uses the local
tree and does not bundle a runtime binary. The helper in examples/_bootstrap.py
uses the installed openai-codex-cli-bin runtime package.
If the pinned openai-codex-cli-bin runtime is not already installed, the bootstrap
will download the matching GitHub release artifact, stage a temporary local
openai-codex-cli-bin package, install it into your active interpreter, and clean up
the temporary files afterward.
The pinned runtime version comes from the SDK package dependency.
Run examples
From sdk/python:
python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py
The examples bootstrap local imports from sdk/python/src automatically, so no
SDK wheel install is required. You only need the Python dependencies for your
active interpreter and an installed openai-codex-cli-bin runtime package (either
already present or automatically provisioned by the bootstrap).
